Using Hybrid WAN to boost UCC UX, productivity

In a recent Gartner study, researchers found that 30 percent of enterprises deploy MPLS and Internet in all branch offices. Therefore, to steer UCC and other application flows, IT organizations require a resilient WAN that uses parallel bounded links.

A very cost effective way for teams to do this is to deploy a hybrid WAN that connects branch offices through multiple links like MPLS, XDSL and wireless Internet. This enables enterprises to amplify bandwidth and offer high-availability UCC services.

Hybrid WAN

Hybrid WANs require dynamic path control to instantaneously select the best WAN link and expedite UCC flows at the same time as other critical applications-flows. This kind of hybrid WAN automatically chooses the best WAN connection for each flow session, taking into account the actual performance of all available links. Traffic metrics including capacity, availability and link quality are used to maximize the UCC and other critical apps UX, while at the same time optimizing the usage of all network resources.

Enterprises require a totally automated hybrid WAN, which accelerates the ROI from UCC tools and optimizes costs associated to unnecessary IT operations. These include management of static policies, and application-specific rules. This hybrid WAN should:

  • Simultaneously maximize UX of UCC tools and other critical applications
  • Centrally orchestrate the WAN infrastructure
  • Select the best WAN connection dynamically
  • Optimize and bound MPLS, Internet and wireless parallel links
  • Reduce costs of Mbps bandwidth
  • Secure direct Internet connections, enable VPN encryption and streamline cloud traffic.

Do not forget to minimize the troubleshooting time of misbehaving ICT resources

As explained in our previous post, aligning application performance with business objectives and amplifying bandwidth and service availability with a Hybrid WAN are fundamental for preventing UCC UX degradation.

Furthermore, the enterprise network ecosystem is becoming more and more complex. In this situation, elements of the LANs and datacenters like routers, WLANs, virtualized devices, cloud services, application servers and Internet services can easily fail, creating performance blind-spots. Moreover, different analyst have warned that most enterprises have deficient procedures to detect, locate and diagnose ITC systems faults.

This is why instantaneous detection and fault location of misbehaving network and application infrastructure elements is crucial for quick diagnosis, finding failure root-causes and ultimately preserving consistent UCC UX. The source of a fault condition can be associated to a bottleneck located at a specific IP address of a WLAN/LAN/WAN device, an Internet URL, or a host. A problem can also be originated within a specific server, a bloc or a series of application transactions between the server and the clients.

Enterprises can dramatically reduce their cycles of troubleshooting UCC tools by pinpointing the location of the problem. Once the source of errors have been correctly identified, then defining and implementing the solution takes much less time. This allows IT organizations to use technologies based on Netflow and deep transaction analysis to accelerate troubleshooting of LAN/WAN devices and application transactions. This ultimately enables enterprises to:

  • React instantaneously to detect and locate LAN/WAN and IT faults affecting UCC UX
  • Improve end-to-end performance network service and visibility
  • Be agile to keep the pace of their IT transformations while speeding their adoption
