Description
Technical Field

Background
Currently, in an operator network, an access gateway is located at a network access control layer and is mainly responsible for service access control, so as to realize functions of dialing and private line access to an internet gateway, a multicast gateway, an IPTV gateway and MPLS VPN PE. For example, the broadband access gateway is responsible for PPPOE/IPOE user management, including access authentication, address assignment, service policy scheduling, and the like. The broadband access gateway is a three-layer terminal node for user access and is a key node for realizing user session management. In daily service operation and development, the index of the number of concurrent users of the broadband access gateway is often required to be improved so as to meet the service requirement. Meanwhile, the broadband access gateway is the main carrier for user multi-service bearing, and the QoS capability of the broadband access gateway directly concerns the quality of various services. The QoS capability of the broadband access gateway mainly comprises an advanced queue scheduling algorithm and a congestion control algorithm, and the multi-stage accurate scheduling is realized on data flow, so that the service requirements of users at different levels of an access side are met.
