                                    | Summary: | This Recommendation aims to specify the signalling requirements for control plane (CP) pool of virtualized broadband network gateway (vBNG). As a basic background, this Recommendation describes the reliability requirement of vBNG and gives the introduction of vBNG-CP pool. And then the framework of vBNG-CP pool are defined. Based on the architecture, the signalling requirements and procedures of services for vBNG-CP pool are discussed. |
