Telecommunications Service Gateway Solution with the Separated Control and Forwarding Plane Architecture

Telecommunications Service Gateway Solution with the Separated Control and Forwarding Plane Architecture

This section describes a telecommunications service gateway solution with the separated control and forwarding plane architecture.

Figure 5-5 Telecommunications service gateway solution with the separated control and forwarding plane architecture

The IT-based telecommunications network is the trend for future network evolution. The SDN and NFV technology as the key technology for IT-based transformation of carrier networks is growing mature. A large number of broadband remote access servers (BRASs) with complex functions configured are deployed on edges of the IP bearer network to function as the gateways for user access. Therefore, the BRAS is the key NE for IT-based transformation of the IP bearer network and the core bearer of intelligence and openness of the entire network. In response to the challenges facing the conventional BRAS, the SDN and NFV technology is introduced and the vBRAS architecture based on the separation between the control and forwarding planes and integrating the advantages of CT and IT is proposed.

In the telecommunications service gateway solution with the separated control and forwarding plane architecture, the BRAS functions are jointly implemented on NEs of the control and forwarding planes.

  • The VNE9000–CP is a control plane NE (vBRAS-CP) deployed in the core DC to implement user control and management, including user access control, user management, authentication, authorization, and accounting, address management, and UP management.

  • The NE40E is a forwarding plane NE (vBRAS-UP) deployed in the convergence equipment room to implement the forwarding of user datagrams, including traffic forwarding, QoS, traffic statistics collection, and dynamic routing protocol.
