Virtual customer premise equipment (vCPE) strategies make it simpler for providers to deploy business services by eliminating unnecessary equipment at the customer premise. The switch to virtualization can make for dramatic CapEx and OpEx savings, but only if vCPE respects customer performance expectations and their QoS SLAs. A new video from Accedian Networks helps providers figure out which path to take as it examines what vCPE is, the components that make it work, and the best places to virtualize traditional CPE functionality in the network.
The ideal vCPE setup would replace racks of hardware with the minimum amount of physical equipment needed to establish, monetize, and maintain the service. Many Layer 3-7 functions can be virtualized without diminishing performance or visibility, so the most common vCPE approaches typically virtualize Layer 3 and higher-layer networking functions like routing tables, VRF, NAT, protection, MPLS, and VPNs. The video takes a realistic look at:
- Structure and benefits of different vCPE architectures
- Trade-offs to consider when deciding where to virtualize
- Different vCPE options, from programmable elements to virtual instrumentation
No matter what architecture providers choose, some form of CPE hardware will still be required to maintain service levels. The video explains not just how to virtualize, but when to not. For example, physical CPEs remain a necessary choice for service demarcation, last mile visibility, OAM & QoS functions, and to deliver services “merchant silicon” can’t.
Virtualizing CPE properly saves CapEx as well as OpEx related to installation, maintenance, and troubleshooting appliances. Early adopters show savings of up to 70 percent in CPE infrastructure costs.
