Embodiment Construction

[0032] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0033] Currently, the industry is discussing the opening of interfaces for router devices to achieve end-to-end routing optimization based on global computing. The present invention utilizes the open interface of the routing device, adopts a centralized end-to-end path calculation method, and sends a dynamic configuration template based on BGP (Border Gateway Protocol, Border Gateway Protocol) to the router through the NETCONF protocol based on a standardized router interface, which can Realize end-to-end channel establishment and traffic guidance.

[0034] in such as figure 1 In the shown scenario, user 1 needs to obtain data from content provider 2, and the data needs to be guaranteed. Congestion occurs between Router 1 and Router 2. There are multiple links between Router 1 and Router 2. In this case, multiple B...

Abstract

The invention provides a method and system for establishing special channels, and a channel calculation device and relates to the field of communication. The method for establishing the special channels comprises the steps of extracting a guarantee bandwidth and address field information between a source end and a destination end from a received guarantee channel establishment request; collecting a network topology from the source end to the destination end and a corresponding link utilization rate in real time; judging whether congested links exist or not according to the collected result; if congestion exists on links between two routers, establishing n BGP (Border Gateway Protocol) Peer pairs between the two routers, wherein the n is greater than or equal to 2; and sending the link allocation condition and routing information allocation condition of the BGP Peer pairs to the routers, thereby providing the special channels for appointed service between the two routers. Through application of the method, network link states can be obtained in real time according to unexpected peer to peer service demands, the BGP Peer pairs are established between the routers and the special links are allocated to the peer to peer service, so the peer to peer service traffic is guaranteed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for establishing a dedicated path. Background technique [0002] With the development of end-to-end services, how to ensure the reliability and efficiency of traffic transmission has become an important issue. Currently, there are mainly the following schemes in the industry to realize end-to-end traffic guarantee, as shown in Table 1: [0003] [0004] Table 1 [0005] Among them, each of the above solutions has its own advantages and disadvantages, and also has different adaptation scenarios. At present, the current network has a greater demand on how to provide end-to-end protection against bursty traffic in the traditional IP network. None of the above-mentioned solutions can achieve this goal. Contents of the invention [0006] The purpose of the present invention is to solve the problem of end-to-end traffic guarantee for burst traffic. [0007...
