Method for ensuring QoS of IP access network service

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...

Problems solved by technology

Therefore, the PVC method of establishing the exclusive bandwidth for users cannot achieve the sharing of network resources. It is not a method that can be generally used in converged access networks, and can only be used for specific applications.
