Embodiment Construction

[0025] Referring to Fig. 1, the present invention does not change the existing networking mode of the access network. A complete IP network consists of the access / edge layer and the backbone layer. The access / edge layer is the network device closest to the user, and is generally composed of low-end switches (layer 2 and layer 3 switches), DSLAM and end office routers. . An end user of an operator's (or enterprise's internal) IP network accesses the IP access network through various access means (XDSL / Ethernet, etc.), and the IP access network converges the service flow to the end-office router, and the end-office router and The backbone network is connected to route and forward the service flow in the access network. The end office router is also responsible for managing access users. The IP access network (access / edge layer) logically consists of multiple access end offices, and each user is managed by one access end office. The router of each access end office is only res...

Abstract

The invention discloses a method for service quality securing in IP access network, the method is: when the network control layer responses the service application for service quality securing and applies network resources to the access network, it uses terminal office router to judge if the access network has enough resources or not; if it can provides enough resource, the terminal office router sends the service quality parameter to user access network end device, the access network end device carries on service quality control, in order to ensure the service quality in access network.

Description

technical field [0001] The invention relates to network access technology, in particular to a method for guaranteeing service quality of IP access network services. Background technique [0002] Currently, the IP network built by telecom operators can only provide best-effort data services. With the development of broadband network users, there are many new telecom service demands on IP, such as voice and video conferencing. These real-time services impose strict requirements on service quality (QoS). [0003] As shown in Figure 1, a complete IP network consists of the access / edge layer and the backbone layer. Composed of a digital subscriber line access multiplexer (DSLAM) and an end office router. An end user of an operator's (or enterprise's internal) broadband IP network accesses the broadband access network through various access means (XDSL / Ethernet, etc.), and the broadband access network converges the service flow to the end-office router, and the end-office route...
