Problems solved by technology

At present, there are many studies on bandwidth proxy, and many organizations and research institutions have proposed their own bandwidth proxy architecture, but the architecture of these bandwidth proxy proposed by them is not perfect, nor does it describe the detailed workflow
[0011] Therefore, there is no mature technical solution available in the prior art, and it remains to be improved and developed.

Embodiment Construction

[0027] The technical solution of the present invention and its beneficial effects will be apparent through the description of the preferred embodiments of the present invention below in conjunction with the accompanying drawings.

[0028] like figure 1 Shown is the architecture and functional modules of the bandwidth agent of the inventive method, wherein:

[0029] 1. Signaling processing module

[0030] The signaling processing module runs the QoS signaling protocol, such as the QoS-NSLP signaling protocol. This module has two external interfaces: one is the interface with the host, and the other is the interface with the adjacent bandwidth agent, which mainly completes the functions of QoS request and other message transmission, negotiation and processing; internally it is mainly the access control module and policy The information base provides the necessary information.

[0031] 2. Policy information base

[0032] The policy information library stores some policy infor...

Abstract

This invention relates to a method for realizing end to end QoS of centralized bandwidth proxy, which contains the service stream sender sending resource request message to bandwidth proxy, said bandwidth proxy sending service stream QoS parameter, strategy information and user authentication information to access control module after receiving resource request message, said access control modulemaking identity authentication to main frame according to said information and information in strategy base, said constrained routing calculation module calculating a optimal path for service stream,said COPS-PR module configuring edge router according to transmitted path selection result and strategy information. Said invention optimizes network resource utilization.

Description

technical field [0001] The invention relates to a method for guaranteeing end-to-end QoS, in particular to a centralized bandwidth agent system structure and a method for realizing end-to-end QoS based on the resource reservation process of the bandwidth agent. Background technique [0002] In order to solve the QoS problem of IP network, many research institutes and standard organizations have devoted great enthusiasm to the research of QoS, and put forward many measures to ensure QoS of IP network. Up to now, there are basically two ideas for implementing QoS on IP networks: one is the integrated service model IntServ, and the other is the differentiated service model DiffServ. [0003] IntServ [0004] The IntServ model was proposed by the IETF. It borrows the traditional circuit switching idea. Before sending data, the sending host first establishes a virtual connection path between the sending host and the receiving host through RSVP signaling, and reserves a virtual c...
