Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] First, the following example is used to illustrate how the present invention establishes the principle of resource recovery in the process of establishing a tunnel link.

[0033] Such as figure 2 As shown, a tunnel (link or path) 1 has been established between device A and device C, and the combination of establishment priority and maintenance priority of the link is (3, 2). When creating a new tunnel tunnel2, If you need to compete for resources with the es...

Abstract

The invention provides a tunnel bandwidth resource recovery method and device used for solving the problem that the efficiency of a new link is lower in the prior art. The method includes: when one target link is new-built, the lowest priority link is kept to start in the new-built link under the condition that the remaining bandwidth resource is deficient, and dismounting is performed on the linkwith the least amount of link numerical data and the smallest link redundancy bandwidth based on selecting the bandwidth which meets the requirements of the target link; the target link is new-builtby the bandwidth obtained by basing on dismounting the link, the optimal available resource bandwidth can be rapidly positioned by the scheme, and the establishment of the new link is guaranteed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for recovering tunnel bandwidth resources. Background technique [0002] When traffic engineering establishes a tunnel, it needs to ensure that all links are provided with guaranteed bandwidth. On the basis of a certain interface bandwidth, it may not be able to meet the requirements of all links. In this case, a relatively common method currently used is to remove other links and use the released bandwidth to meet the requirements of the current link. Establish the required guaranteed bandwidth. In the bearer network, a set of resource recovery principles is defined, and based on this, a data management center is established to provide it for use by different traffic engineering. When resources are insufficient, it provides a basis for quickly recovering and preempting resources. [0003] figure 1 Describes the process of bandwidth resource management in traffic ...
