Technical Reports

BBF's CloudCO projects have resulted in the following Technical Reports

TR-384: CloudCO Reference Architectural Framework

This specification defines the reference architectural framework of the CloudCO. Functional Modules are defined, but not the details of their internal operation. This framework starts from basic Northbound API capabilities so that function composition, initialization, and management of the CloudCO resources can be supported and created as a byproduct of end-to-end service composition.

This specification is the first phase in a multiphase project. Additional work is underway to include migration, detailed interface definitions, test cases & application notes, use cases & scenarios and reference implementations. Progress on these projects can be seen on the BBF members sites:

TR-416: CloudCO Use Cases and Scenarios

This specification defines 14 CloudCO Use Cases. Some of the use cases are enabling legacy scenarios, some new CloudCO-only use cases are also described. The intention of the uses case are to test the validity of the architecture, and will allow consideration of the information that needs to be exchanged across the interfaces between the functional blocks of the architecture.

Each each of the following use cases covers the architectural diagrams and actors involved:
  • Residential Broadband Access using PPPoE
  • Residential Broadband Access using IPoE/EAP
  • Fixed Mobile Convergence – Interworking
  • IPv4 Address optimization with CGNAT
  • Parental Control
  • Lawful Intercept
  • Network Enhanced Residential Gateway (NERG)
  • Hybrid Access
  • Virtual Business Gateway
  • Residential Broadband Access, User watches IPTV
  • Business Broadband Access, L2VPN activation
  • Fixed Access Network Sharing (FANS)
  • Public Wi-Fi Access
  • Home network virtualization scenario

TR-317: Network Enhanced Residential Gateway

TR-317 specifies the Network Enhanced Residential Gateway (NERG) architecture. NERG consists in shifting some of the functionality of a residential gateway (RG), as defined in TR-124 [6], to the operator’s network.

With NERG, the functions provided traditionally by the RG are now distributed between ant on-site device called a BRG (Bridged Residential Gateway) and a network based component, called a vG (virtual Gateway). The vG is part of a flexible hosting environment that can benefit both from network equipment and recent network virtualization technology.

This Technical Report describes the motivation to deploy NERG, based on the use cases that it enables. In particular, NERG facilitates per subscriber per device services, LAN extension and simplified end user operations. Service providers looking for additional service offerings, such as personalized services, Smart Home and enhanced multimedia services, may find significant benefits in deploying NERG.
