The Carrier Ethernet market is a proven revenue-driver for communications service providers (CSPs), and by all accounts, it will continue to be so in the coming years. By 2017, the Carrier Ethernet market is expected to be worth $100 billion, and by one year later, revenue from these services is predicted to be 300 percent higher than it is now.
For some CSPs, such as Cable MSOs and competitive carriers, it offers new business opportunities and may sound like a windfall for the industry, but for many, it’s at the expense of high-margin legacy TDM services. Regardless, all are being motivated by the same core driver, time-to-revenue.
As I explained during the Metro Ethernet Forum (MEF) GEN14 panel, “Unlocking Revenues with Standardized Carrier Ethernet 2.0 Wholesale E-Access Services,” the key to demonstrating and differentiating the value of Carrier Ethernet services begins with standardized performance visibility. The visibility maximizes the value of the service to business customers and the standards optimize the cost-effectiveness and delivery times, ultimately accelerating time-to-revenue.
In this video, I explain how visibility defines the customer experience. I explore a shipping company’s case study, in combination with a personal story of ordering a guitar for my daughter’s upcoming birthday and tracking the delivery all the way to my doorstep. These examples parallel the importance of Carrier Ethernet performance visibility and how it impacts the value of a service:
It’s this same simple visibility I described in the video – the ability to login and see data right away – that business customers crave. As our “Pulse of the CSP Market” survey found, 70 percent of CSPs say their customers would value more sophisticated reporting.
The other piece of the puzzle, in addition to visibility, is MEF’s Carrier Ethernet standards, which help bridge the gap between what customers want – real-time data, self-service analytics, historical insights and more – and what CSPs actually give them. There’s also a clear revenue play that can’t be overlooked. If these standards help CSPs establish faster time-to-revenue for business services and simplify network and service performance management, then customers will value the service more. And if they value the service more, they’ll be willing to pay more for it.
By aligning industry standards with enhanced performance visibility, CSPs can position themselves to improve their time-to-revenue and get the most out of the burgeoning Carrier Ethernet market.]]>
Increasing the speed of service activation, alongside optimizing network services pricing is still causing headaches for communications service providers (CSPs). Incremental network technology improvements and other tactics haven’t quite been able to cut it, and CSPs are looking toward new technologies such as network functions virtualization (NFV) and software defined networking (SDN) to bridge the gap. This was confirmed in a recent Heavy Reading survey, where it was revealed that service agility and flexibility is the key factor influencing companies’ NFV deployment decisions.
So, what’s the catch? To be in a position to realize the benefits that agile network services present for operators, they must first make organizational changes, upgrade their Network Management Solutions and fully deploy end-to-end instrumentation of their existing network services. In fact, 57 percent of Heavy Reading survey respondents understood that considering service assurance prior to the deployment of SDN was critical.
To succeed with NFV and SDN, business service providers must strike a balance between delivering a consistent quality of service (QoS) and increasing their network services agility. This requires an update of the current inflexible service assurance systems that were designed for legacy networks and are unable to handle the increased complexity and agility that make up today’s network service architecture.
The exponential increase in the number of virtual network functions (VNFs) will lower engineering’s and operation’s visibility on network function capacity and performance. This visibility issue can be overcome by offering holistic dashboards that are agnostic from the virtualization stack.
By upgrading their OSS to become “real-time,” CSPs will allow real-time provisioning/synchronization between various elements (activation, configuration, performance, billing, etc.). By bridging siloes and making organizational roles clear, network and IT engineers can increase their cooperation and succeed in introducing a new IT stack in their network’s architecture.
As lofty of a goal as this “real-time” OSS may seem, it is possible, it is worth it and it can be achieved in a relatively short timeframe. An end-to-end, next-generation service assurance solution enables mobile and fixed line operators to handle the scale and dynamics of a virtual network. By considering service assurance before embarking on NFV or SDN implementations, the transition becomes seamless, and service quality will be maintained.
InfoVista and Heavy Reading have developed a five-step service assurance maturity model as a guide to help CSPs transition to NFV and SDN:
The opportunities that NFV and SDN hold for the CSP are plentiful, and the long-term ROI will certainly be worth the up-front effort. But, to reap those rewards, operators must be proactive in their approach to continue to deliver on customers’ expectations throughout the transition. The proper planning and attention of service assurance has become a critical part of CSPs’ success.

In the last four years alone, more than 1 billion people have gained mobile network access, bringing the global total to 3.2 billion mobile subscribers – nearly half the world’s population. And we’re only about another four years away from crossing the next significant milestone – 4 billion global subscribers.
Historically, this rapidly growing landscape has translated to fierce competition between mobile operators for new customers. But, as some markets reach saturation and the well of new customers dries up, mobile operators must focus on keeping the customers they already have satisfied. And that’s not an easy task, given that competitors are around every corner, coming up with new incentives, such as paying early termination fees, to woo subscribers away from their current mobile operator.
So with fewer new customers on the market, and lost customers almost certain to not return, what can mobile operators do? Many have found success in first addressing the most common reason customers leave in the first place – poor quality of service (QoS).
The Service Puzzle
The top reasons for mobile customer churn are generally related to QoS, whether subscribers think they’re receiving insufficient value for their money or they’re frustrated with poor network quality. What’s worse for operators is that these problems rarely exist in a private vacuum.
Any time subscribers experience service problems, whether it’s a serious outage or constant, ongoing degradation, they will voice their complaints through social media, sometimes so loudly that news outlets pick up on the story. The resulting storm of criticism damages the operator’s reputation and can increase churn, which, in turn, jeopardizes revenue.
To prevent these losses, operators need to understand why QoS problems are happening in the first place. Network problems have been on the rise for two reasons – networks today are increasingly complex, and subsequently, operators lack visibility across those networks. Together, these factors make it difficult for operators to monitor QoS and then act quickly to address any problems.
But, these limitations are avoided when mobile operators apply end-to-end mobile service assurance. By gaining a full, near-real-time view of the service delivery chain, in a single dashboard, mobile operators can respond quickly to service problems and deliver on the agreed upon KPIs, meaning less performance degradation and network downtime for customers, and improved QoS.
Meeting the expectations of 4 billion mobile subscribers isn’t easy, but it’s more within reach when operators apply end-to-end mobile service assurance
To learn more, see our video, “End-to-End Mobile Service Assurance: Keeping Customers Happy.”]]>
Today’s mobile networks are increasingly dense, complex and heterogeneous, thanks in large part to the trend toward virtualization. In addition, operators must consider the burden of ongoing, exponential mobile data traffic growth on their networks.
Unfortunately for mobile operators, just as network management is becoming more of a challenge, customer expectations for consistently high quality of service (QoS) have increased – subscribers are demanding unwavering mobile performance, or they will churn at the drop of a hat.
While mobile operators may aim for 100 percent customer satisfaction, the above-mentioned factors make that expectation for a high quality of experience (QoE) unrealistic. Instead, the best that mobile operators can do is ensure optimal QoS for as many of their subscribers as possible, starting with their high-value customers.
Indeed, not all subscribers are equal in regards to the revenue they represent for a mobile operator, which is why RF engineers must prioritize QoS troubleshooting activities for these VIPs. With the right approach, mobile operators can maintain a great level of customer experience and minimize churn. Vital to their success is having a tool with the power to analyze millions of calls, or simply just one from a VIP!
One key to efficient, targeted network troubleshooting is to utilize live mobile call trace data, which provides mobile operators with the real-time, geo-located data they need to address high-priority QoS problems. Equipped with the right tool, RF engineers can leverage thepower of call trace data to make mobile network troubleshooting more efficient and effective.
The troubleshooting process begins by translating network and subscriber information – that is, the subscribers’ network activities and associated signaling – into actionable, customer-centric intelligence. Mobile operators can then apply that intelligence to proactively identify which subscribers are being impacted the most by network issues, and where network investments will elicit the highest improvements in QoS.
By understanding the individual experiences of subscribers, sorted by KPIs like dropped call and call success rates, mobile operators can better focus on the network problems that are causing the most harm to the customer experience, as well as service those VIP customers whose churn would most impact the operator’s business. By following this troubleshooting process, mobile operators can maximize customer retention and, in turn, their revenues.
Watch our new video to learn more about how customer-centric mobile network troubleshooting and optimization are helping mobile operators add a personal touch to customer service and deliver a better customer experience where and when it matters most, including in today’s most complex, multi-vendor and multi-technology network environments.]]>
Today’s mobile operators have a lot on their plates. They must manage increasing mobile data volumes and deliver a high quality of experience (QoE), all while keeping CAPEX and OPEX in check. Without a clear view of the end-to-end network, each of these individual tasks are difficult to achieve – let alone all at once!
In the past, mobile operators have struggled with keeping data within their mobile network planning projects up-to-date. Given how tedious the collection of this information was, RF engineers too often had to rely on outdated network data and limited information about the mobile network performance, resulting in sub-optimal use of network investments.
With live mobile network planning, this is no longer a problem. This method takes into account three unique data types – geo-located call traces, network performance key performance indicators (KPIs), and live network configuration and parameter settings – to provide RF engineers with timely and accurate insight into their mobile networks’ current status. Tracking these data types allows evolving traffic demands and existing network issues to be addressed, providing a complete tool box for efficient and integrated network planning and optimization, all in near real time.
First and foremost, by incorporating mobile call trace data from different vendors and geo-locating it with a powerful geo-location algorithm, live mobile network planning enables RF engineers to accurately predict radio propagation through detailed network modeling. Geo-located call trace data gives a remarkably good view of where mobile devices are used, and is an excellent input to small cell planning. All of this can ensure that small cells are placed where they are really required. And, based on call trace data, live mobile network planning also provides a view of indoor vs. outdoor traffic, thus making a huge impact on planning decisions. Lastly, live mobile network planning shows where network upgrades are needed based on the most valuable customers’ usage patterns.
Network performance counters, also known as KPIs, offer a good view of the network’s quality and traffic. They explain how the network performs, along with what the quality is now and how it has evolved over time, which part of the network works well, and which parts will need some additional attention to perform as expected. By selecting and analyzing KPIs for different times of the day or week, RF engineers really get to know the mobile network and understand its strengths and limitations. But, the integration with a network performance management solution offers even more. At their fingertips, RF engineers get current traffic and LTE cell loads that they can use as input to traffic maps and network analyses. They also have the ability to forecast the traffic development in the mobile network based on the actual traffic during the last few months.
Last, but not least, live mobile network planning projects can be updated with the live network’s configuration and parameter settings. Besides keeping planning project data up-to-date, this enables a long row of interesting use cases, such as on-air status and implementation control. It helps RF engineers answer questions like: “Has the network been implemented according to the optimized plan?” and “Have changes and mistakes made to the plan during the implementation phase caused the network to under-perform?”

As of earlier this year, mobile operators across more than 100 countries have adopted LTE, motivated by the opportunity to gain additional network capacity and ensure faster speeds for subscribers. In the U.S. alone, mobile operators will spend an estimated $138 billion on LTE networks over the next five years to continue delivering on those initiatives.
Yet, despite the deployment of next-generation 4G/LTE networks, mobile operators will still be faced with the challenge of keeping quality of service (QoS) consistent and delivering the best possible quality of experience (QoE) for end users, while keeping OPEX and CAPEX for these new networks at a minimum.
If an integrated network planning and optimization practice is adopted early on, mobile operators will see better results with their 4G/LTE deployments. This is an important step in improving the efficiency of mobile operators’ PLAN-BUILD-OPERATE cycles, which are becoming increasingly important with new 4G/LTE deployments.
Additionally, by gaining an end-to-end view of all the subscribers relying on their networks, and the performance each is experiencing, mobile operators will be better equipped to improve network efficiency and ensure holistic network performance. Mobile operators will also be able to apply this real-time, predictive network intelligence to make better use of their existing network assets, thereby improving CAPEX and OPEX efficiency.
Over the next month, InfoVista will be presenting on the importance of unified network planning, optimization and service assurance for LTE networks. First, join us this week at LTE Africa 2014, where InfoVista’s Astrid Wastegard will be participating in a panel discussion, “Highlighting the Importance of Gaining Consumer Insight & Managing Network Performance for QoE.” You can also stop by our booth (#C15b) to learn more how InfoVista is working with customers in the region to improve mobile network performance.
We’ll also be presenting at LTE North America 2014 (Booth #59g), November 18-20 in Dallas. During that event, Bernard Breton will be participating in a panel discussion, “Performance Optimization in Mobile Networks.”

Recently, I hyperbolized Carrier Ethernet’s ‘world domination.’ However, statistics show that that is actually not too far off, particularly in terms of Ethernet services’ global revenue projections and port growth. Infonetics Research forecasts 300% revenue growth for Ethernet services by 2018, and Vertical Systems Group estimates that there will be one million Ethernet ports in the U.S. alone by 2018. Clearly, there is money to be made from both wholesale service providers and enterprises purchasing these services to take advantage of their flexibility, cost-savings and ubiquity.
Getting these revenues should be easy for communications service providers (CSPs). The Metro Ethernet Forum first standardized Ethernet services and has since evolved that to support interconnected, managed, business-class connectivity services. So, what is left for CSPs to do?
It turns out that there is a lot of work to finish and a lot of challenges to overcome. Challenges include the time required to turn up new Carrier Ethernet services, especially if it involves an off-net (or out-of-franchise) location, access technology availability (fiber, microwave, copper, coax), and the management and operation of these services, which is exacerbated by the gap between specified best practices versus current implementation (or lack thereof) of these best practices.
Considering that the primary business driver I hear from our CSP customers is time-to-market and, by extension, time-to-revenue, anything that stands in the way of getting Carrier Ethernet 2.0 services deployed, running and billed is a target for elimination or optimization. When it comes to management, specifically service assurance and network performance management, the standards (e.g. MEF Specification 35) should help. Yet, MEF 35 is being adopted slowly as network equipment providers find implementing its broad scope time-consuming; they struggle to determine which part of the standard to focus on first. End customers are asking for the standards, but there is confusion amongst operators regarding which network and service performance monitoring and SLA metrics to expose and how. This situation leaves CSPs with the arduous task of normalizing the multiple, vendor-unique (sometimes proprietary) ways of monitoring Carrier Ethernet performance. It is an expensive and time-consuming task, and ultimately delays that critical time-to-revenue driver.
The present solution is to take advantage of sophisticated software that bridges the gap between the future standards and vendor-specific implementations. Perhaps it’s Y.1731 synthetic test probes, vendor-proprietary OAM, transport-level OAM or even moving up to the IP layer with shadow routers and TWAMP. This normalized visibility is the key ingredient to reaping the financial rewards available from the wave of Carrier Ethernet demand in the global marketplace. Having such a solution cuts down on the implementation time for service delivery, while the market continues to coalesce on the MEF management standards.
When speaking with one of our customers, I heard an obvious, yet startlingly simple revelation: the biggest request from their customers is the ability to see information when the customer wants: on-demand, in near real-time. They don’t want to wait. Having that capability is enthralling (our customer’s words, not mine) because today’s digital, consumer-based world is short on patience. It’s like tracking a package – they want to know what’s going on with their important assets. CSPs that can provide that visibility, with a standards-based approach, stand to reap the greatest financial rewards.
To learn more about this topic, I invite you to join me at GEN14’s Unlocking Revenues with Standardized CE 2.0 Wholesale E-Access Services panel. Hosted by Rosemary Cochran, principal and co-founder of Vertical Systems Group, the session will explore the full lifecycle of an E-Access service; I will speak alongside participants from Time Warner Cable, Iometrix, Veryx and Verizon.

OSS is sexy. That is, according to Ray Le Maistre of Light Reading. That comment likely elicited one of two reactions from readers: surprise at the statement’s absurdity, or appreciation that OSS may finally be getting the attention it deserves.
Whatever your reaction, it’s clear that we are experiencing one of the most exciting technology evolutions our industry has experienced in the past 20 years. As network controllers are being introduced in various network domains, and network functions are let loose from the bonds of ASICs and network equipment, the boundaries of OSS functions – e.g. network management, service delivery, service fulfillment, service assurance and customer care – are becoming far more difficult to identify. In that context, it is mandatory to ensure that the technology evolutions we introduce in our networks will not be deployed at the expense of customers’ service quality. As network technologies increasingly rely on an IT stack, CSPs’ network and IT operations teams must learn to work together and cooperate in what BT calls the Third Way. The network services innovations that NFV and SDN are offering us are well summarized in the MEF Third Network whitepaper, describing their Network as a Service (NaaS) vision, which should shape CSPs’ networking technology evolution for the next decade.
While NFV/SDN technologies are revolutionary, CSPs’ operations will not align with a big bang transition. To better understand the operations management challenges sparked by NFV or SDN, one must look back at the wave of virtualization that took place more than a decade ago in x86 and Unix-based computer systems. At the time, IT departments were running data centers under capacity – sometimes at just 15 to 20 percent – and began virtualizing system after system to maximize their utilization and reduce back-end costs like HVAC systems, power and space. As the ability to implement new virtual systems became even easier, IT departments were suddenly faced with the challenge of virtual server sprawl. Because a new virtual machine could be spun up in minutes or even seconds, IT departments were soon managing more than twice the number of systems that they previously had, trading their gains in operational efficiency for increased management complexity and costs.
It would appear as though the entire CSP industry is about to experience a similar situation as IT departments did when virtualization became more popular – one that CSPs must also learn from.
Thus, the questions one must ask are: “What is required of the OSS to support a dynamic and virtualized network service infrastructure based on NFV?” and, “What is required of the OSS to increase network configuration automation in new networks while managing legacy technology in others; knowing that the transition will last 5-10 years ?”
Standardized information models, flexible solutions, service models and standardized APIs are the foundation for a real-time OSS approach that would allow the introduction of innovative network controllers and orchestrators while also managing customer’s service quality expectations. This was reiterated by Colt at the OSS in the Era of SDN & NFV event this week in London, arguing that end-to-end service quality measurements will remain a reference for SDN controllers and NFV orchestrators introduced in various networks.
When it comes to service assurance and performance, in particular, InfoVista has examined the transition from today’s physical network function-dominated environment to the future of NFV and SDN. To learn more about these steps and to get a first-hand look at InfoVista’s Service Assurance Maturity Model, I encourage you to join me at the Metro Ethernet Forum’s GEN14 event later this month and attend the panel, “Assuring Service Performance and Quality over Virtualized & Dynamic Networks”, on November 19th. During this panel, we’ll discuss service assurance needs from both CSP and OSS perspectives with Cox Communications, CENX and Spirent. I look forward to seeing you there and invite you to contact InfoVista if you are interested in setting up a meeting at the show!]]>
At Metro Ethernet Forum’s (MEF) GEN14 event, the forum announced their Third Network vision, but will the Network-as-a-Service vision work?
Just when the industry was beginning to settle on the debate of what software defined networking (SDN) truly means, or at least starting to coalesce on its meaning, the MEF boldly announced its vision for the future and for its membership under the umbrella term of the Third Network. This is a daring step for the MEF as the vision shifts its core focus of accelerating the adoption of Carrier Ethernet services, to developing the programmatic architecture to support Network-as-a-Service (NaaS), whether that network be Carrier Ethernet based, IP-VPN based or something else.
As I speak with our customers and industry leaders, I hear a lot of different thoughts and opinions regarding SDN, network functions virtualization (NFV) and NaaS. Some say, “forget NFV, we are focusing on SDN.” Others suggest recently launched bandwidth-on-demand features of their network offerings are, in essence, a form of NaaS. Many indicated that NFV is the first priority. Regardless, the shift in the MEF’s focus continues to place greater emphasis on software, operations and management of network services beyond straight implementation. The beginnings of this shift can be traced back to the instantiation of the MEF’s Service Operations Committee in mid-2013. That summer, I was lucky enough to be part of the inaugural Service Operations Summit, participating on a panel that was hosted by Oracle’s Stephan Pelletier, which addressed Ethernet operations from the perspective of the supplier.
The panel was very well received and since that time the Service Operations Committee has grown significantly in terms of membership and activity at the MEF. It has also proven that once standards are in place and adopted to govern the transit of frames from one location to another, there’s still the broader challenge of management. Not only management of the network, but the business processes to order the network service, deliver it, change it and turn it off. The management refers to delivering services to off-net locations and working with one and sometimes two or three intermediary Ethernet operators to deliver a complete end-to-end service.
At the GEN14 proof of concept (POC) showcase, I was excited to continue that momentum in collaboration with Oracle to demonstrate a Carrier Ethernet service using the concepts and constructs of the Third Networks, which enables agile, assured and orchestrated services. We will focus on the assured component, but the purpose of this POC is to articulate with a live demonstration, the pieces that go together to enable service fulfilment using a self-service Web portal. That service is then automatically instantiated, monitored and assured in real time. The service is dynamically orchestrated across multiple operators (a service provider and an access provider), and full performance visibility is provided to internal (communications service providers) and external (customer) stakeholders. Here’s a brief summary of what you can expect to see in this POC:
We were very excited to work with Oracle on this POC and to demonstrate the flexibility of the InfoVista solution that exists today. The goal is to support and enable these new concepts and help our customers, when they are ready, to achieve the benefits of the Third Network.
For more details see the white paper co-authored by InfoVista with our MEF member colleagues or check out my first post in this four-part series, GEN14: Carrier Ethernet Sweeps through Europe & the Fine Art of Service OAM.]]>
Recently, Frost & Sullivan’s research analyst Shuba Ramkumar discussed retail Carrier Ethernet services in Europe based on her report, European Retail Carrier Ethernet Services. Following a similar pattern as North America, the popular service of choice are E-Lines, those wonderful point-to-point connections that prove very useful in replacing the less flexible and more costly TDM services. And, as was found in North America, the growth of E-LAN multi-point-to-multi-point services is expected to drive growth over the next three to four years.
In my own personal experience, I’ve noted a significant increase in activity with wholesale access providers in the European region. This is especially the case in Central Europe, which suggests that E-Access services, specialized point-to-point connections to connect off-net locations, are likely to see a strong uptake.
These predicted growth patterns will put pressure on layer 3 services in some markets and, as is the case elsewhere in the world, some of those higher-margin layer 3 services may suffer some cannibalization. Thus it’s crucial for communications service providers (CSPs) to ensure they can offer the same level of quality on their layer 2 service, especially if it’s taking business from another CSP’s layer 3 service. Furthermore, they need to maximize the revenue potential of Carrier Ethernet. That approach supports Shuba’s comments regarding investment areas for the CSP, specifically in terms of the service wrap around the Ethernet service where she points out self-service portals and performance management services. Why? Because they enhance value for the retail enterprise purchasing the service. If value is improved, revenues can be solidified and even grow.
At InfoVista, we’ve supported our customers in delivering the highest quality of service while providing service tiers that can be directly monetized in terms of value-added performance management services. For example, InfoVista offers not just utilization metrics, but end-to-end, analytics, forecasts (who doesn’t want to know when their E-Line is going to run out of capacity?) and self-configured thresholds.
Part of this investment strategy for CSPs is to ensure they not only get the market share they need, but maximize the revenue potential of that customer base for service operations, administration and management (OAM). Service OAM is crucial for two reasons. First, it is the tool to maintain and guarantee quality in terms of the service level specification for the Carrier Ethernet service. Second, the provider domain Service OAM (the end-to-end from customer edge to customer edge) is what delivers those meaningful metrics that enterprise IT and network managers rely on, latency or frame delay, frame delay variation and frame loss. If you haven’t been exposed to designing and configuring such Service OAM, you may be thinking, “great, that shouldn’t be a problem!” You may even be happy to know that the Metro Ethernet Forum (MEF) has a number of specifications governing the best practices for Service OAM and performance monitoring, namely MEF specification 35. The rest of you realize that this is perhaps easier said than done.
There are many challenges for Service OAM. First, the MEF standards aren’t available in today’s equipment. Related, and technically encompassed, standards from the ITU, for example, are understood to be ubiquitous. But, as the saying goes, ‘the devil is in the details’; did you know there have been eight versions of ITU’s Y.1731? Which version is included in vendor A’s model, XYZ device? Is that compatible with the version in vendor B’s model T device? Is the entire standard implemented, or just parts of it? Is the vendor using canonical terms or vendor-branded terminology? Thus there is an art to understanding what’s possible and, perhaps as confounding, how to set it up in the network. What’s the CLI command, or EMS GUI workflow to configure MEPs? Should it be up MEPs or down MEPs, and do you have a choice?
If, like me, you have questions similar to these, I encourage you to join me at the GEN14 pre-event, the MEF Certified Professionals Convention, on November 17th, 2014. I’ll be on a panel with member colleagues (and coincidentally two other Canadians) from EXFO and FibreNoire where we will explore some of these questions and understand a bit more of the science and the art of Service OAM. I look forward to seeing you there and invite you to contact InfoVista if you are interested in setting up a meeting while at the show!]]>
