Broadband access method and device, and virtual broadband remote access server system

Abstract

The invention provides a broadband access method and device, and a virtual broadband remote access server system, relates to the technical field of communications, and used for improving the performance of a control surface of a broadband remote access server and realizing the centralized management of the BRAS (Broadband Remote Access Server) in a network. The method comprises the following steps: receiving an access request sent by data surface equipment; sending an authentication request to an authentication server according to the access request; receiving an authentication result returnedby the authentication server, and judging whether the authentication result is that the authentication is passed; if yes, then allocating an IP address to terminal equipment, generating a routing table entry of the terminal equipment and generating QOS strategy information of the terminal equipment; and sending the IP address, the routing table entry and the QOS strategy information to the data surface equipment, so that the data surface equipment forwards a data message sent by the terminal equipment according to the IP address, the routing table entry and the QOS strategy information. The broadband access method provided by the invention is used for the control and management of broadband access.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a broadband access method, device and virtual broadband remote access server (Virtualization Broadband Remote Access Server, VBRAS system) system. Background technique [0002] Internet protocol (Internet Protocol, IP) metropolitan area network includes two parts: the metropolitan area backbone network and the metropolitan area access network. The metropolitan area backbone network is divided into the core layer and the service control layer. ), responsible for the tandem of service access control point devices, routing and high-speed forwarding of traffic, and also serving as the egress of the IP MAN. The service control layer is composed of broadband network gateway control equipment (Broadband Network Gateway, BNG), which realizes centralized access and control of services. [0003] The BNG includes: a BRAS and a full-service router (Service Router, SR). Among...

AI Technical Summary

Problems solved by technology

Traditional hardware-based BRAS control plane performance is generally poor, and the large session control (Session) bearing capacity is weak. Therefore, with the increase of broadband user bandwidth and traffic, and the development of new services such as 4K HD and the Internet of Things, traditional BRAS is facing huge challenges. challenge

In addition, a large number of BRASs are required in the network to complete the data access of the user broadband network. In application scenarios such as network construction and new service launch, it is necessary to configure and upgrade each BRAS one by one. Therefore, the configuration management is complicated, and the activation response is slow. Slow business launch
