Many CSPs are productizing or launching commercial-grade network-as-a-service (NaaS) products that include on-demand Ethernet and vCPE. Some examples of commercial deployment of NaaS services are AT&T Network on Demand and Colt DCNet-as-a-service. These solutions provide an array of benefits to the business service customer, including fast service activation, as well as self-service purchase through customers’ portals. Best of all, network services can all be virtualized either on the customer premise or in the CSP’s point of presence (PoP). This translates to reduced OPEX and CAPEX and an opportunity to further monetize the network with value-added services such as application visibility and control as well as security services.
