Abstract:
This paper presents Telefónica approach for virtualizing
residential customer premises equipment (vCPE), showing how the equipment at a customer's home can be simplified and how the
management of resources and services improves as a result. This use case of virtualization enables the operator to
shift most functions from the residential gateways towards the carrier own network, by running them on general-purpose servers at the
operator premises. This makes it possible that network functions such as IP routing, IP address management (DHCP), address translation (NAT), firewall, Set Top Box functionalities (live TV,
VoD, etc.), etc. are maintained and upgraded from the most efficient location. Because of the expected
high impact onto the economics of the Telco network operations, the virtualization of the CPE is considered by the authors as one
promising use case of Network Virtualization technologies. The virtual CPE approach is being tested in Brazil (where Telefónica operates
under the Vivo brand), and represents a great opportunity for learning lessons on development and deployment of Virtual Network Functions
(VNFs). Some of them are summarized in this paper.
