Problems solved by technology

In this way, during the subsequent service establishment process of network element B 220, all or most of the multiple services from network element B 220 to network element D 240 via network element C 230 will be because network element C 230 cannot provide sufficient link bandwidth failed
[0020] When the current network convergence method is applied, the above-mentioned user service establishment failure is very likely to occur, resulting in a low success rate of user service establishment.
And with the rapid increase in the number of users, in the current network communication field, the above-mentioned network elements receive multiple routing calculation requests one after another within a period of time, and all or most of the service establishment fails in the subsequent service establishment process. Occurs frequently, resulting in a low success rate of user business establishment, seriously affecting user satisfaction

Embodiment Construction

[0052] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] The key point of the method of the present invention is that: after the network element receiving the route calculation request from the user successfully calculates the service route, it will establish a service for the user; The pre-decremented TE resource value; the network element that receives the pre-decremented TE resource value updates the pre-decremented TE resource value of the corresponding network element saved by itself according to the pre-decremented TE resource value. In this way, each network element in the network can know in a timely manner what changes have taken place in the TE resource values ​​of which network elements, and when receiving a route calculation request, the TE resource values ​​of each network element on which the route calculation is based are all The latest TE resource value makes the service esta...

Abstract

This invention discloses a method for realizing network convergency, in which, after computing a service route successfully in terms of a user request, the NE will set up service for the user, get a pre-deducted TE resource value based on the service route computation result and flood the value, the NE having received the value refreshes its own stored pre-deducted TE resource value corresponding to the NE based on said value, thus, the elements in the network can get to know the TE resource values of which NE are changes and computes the routes based on the new TE resource values after receiving succeeded route computation requests so as to greatly increase the success for setting up services after computing routes successfully.

Description

technical field [0001] The invention relates to the field of communication networks, in particular to a method for realizing network convergence. Background technique [0002] In the current network communication field, especially in the intelligent optical network, each network element is set as follows figure 1 The route calculation module shown is used for calculating service routes. figure 1 It is a structural diagram of a route calculation module in a network element, wherein the route calculation module 110 of the network element 100 includes a route calculation execution unit 111 and a traffic engineering (TE) database 112 connected to the route calculation execution unit 111 . [0003] The route calculation execution unit 111 in the network element 100 is provided with a route calculation request interface, and the route calculation execution unit 111 receives the route calculation request from the user through this interface, and applies the currently very common s...
