DESCRIPTION
Technical Report 317 (TR-317) from the Broadband Forum specifies a "Network Enhanced Residential Gateway" (NERG) that can be used by service providers (SP) to deploy residential broadband services including High Speed Internet access, IPTV and VoIP services. A new device type named BRG (Bridged Residential Gateway) is defined, as well as a functionality split between what it would run and what a virtual function instantiated in the SP's cloud, called vG, will run. This functionality split allows for the introduction of new services not possible with the existing whole-physical residential gateway. It also saves operational cost with less changes / truck roll in and to the customer residence would be needed.
Key for this use case is:
- ONAP will be used to instantiate, configure and manage the vCPE service as a cloud service that may be collocated with other subscriber services such as vSTB, cloud DVR and VoD-streaming vCDN.
- SDN is used to configure the connectivity with the first mile network, the IP subscriber management and service edge networking. Potentially in the future, dynamic service chaining to value-add services (e.g. security, parental control, home automation IoT).
The full details for this this new residential gateway can be found in the BBF report. For ONAP Amsterdam Release (Nov 2017) a subset of the full functionality of TR-317 will be included in the VNFs implementing the vCPE use case; but the ONAP behavior for the use case will be mostly what will be expected from ONAP in a production network.
The diagram above depicts the R1 vCPE use case (with the exception of the home networks on the left which will not be part of the tested use case). The IP addresses and VLAN numbers are for illustration purposes, the actual values may be different in the final set up. In particular, IPv6 addresses may be used in place of IPv4 10.x.x.x in the above.
Users and Benefit:
- Residential users benefit from subscriber specific cloud services and automation that does not need truck roll installation, local configuration and management of LAN/NAT/WAN/VPN networking.
- Authenticated subscribers may access similar broadband services outside the home residence using other wireline or wireless access networks.
- SPs benefit from a more flexible platform to evolve residential broadband services that do not depend on the lifecycles of provided home devices (e.g. STB, WiFi access router, modem etc…)
