Problems solved by technology

[0009] Considering the above problems, the present invention is made. Therefore, the main purpose of the present invention is to provide a method and device for aggregated link management to solve the problem that the bandwidth does not meet the pre-planned requirement due to the change of the aggregated link bandwidth in the prior art. When the business traffic bandwidth is required, the aggregated link still carries the traffic loss caused by the business traffic

Embodiment Construction

[0028] Aiming at the problem in the prior art that the service flow loss and the service cannot be normally switched to the backup link due to the change of the number or type of sub-links, the present invention solves the problem by setting parameters (that is, the bandwidth threshold mentioned above). Identify the use and change status of the actual available bandwidth of the aggregated link, so that the aggregated link can display the bandwidth attribute at the same time on the basis of externally displaying the connectivity attribute, thereby avoiding the business failure caused by the aggregated link without actual bandwidth constraints in the prior art Traffic is lost, and the issue of enabling the backup link cannot be triggered in this case.

[0029] method embodiment

[0030] In this embodiment, a method for managing aggregated links is provided.

Abstract

The invention discloses a method for managing link aggregation and a device thereof, wherein, the method comprises: according to the service carried by the link aggregation, the bandwidth threshold value of the link aggregation is set, wherein, the bandwidth threshold value is the smallest bandwidth value required by the bearer service; the available bandwidth of the link aggregation is obtained, and according to the available bandwidth and the bandwidth threshold value, the carrying and / or the changeover of the service flow by the link aggregation are / is controlled. By the technical proposal, the circumstance of the actual available bandwidth of the link aggregation is marked by introducing the parameter bandwidth threshold value, and the problems, caused by the change of sublink numbers or type change, are avoided that the service flow is lost or the service can not be switched to the spare link normally.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for managing aggregated links. Background technique [0002] An aggregated link is a uniquely identifiable entity formed by any grouping of one or several ports, and it contains several sub-links. A sub-link is usually a physical link formed by connecting a pair of actual physical ports through a transmission medium. Aggregated link is also called relay or bonding technology (Bonding), which "bundles" multiple physical link segments with the same transmission medium type and the same transmission rate. The aggregated link is logically a whole. Its internal composition and the data transmitted by it are transparent to upper-layer services. [0003] Since the aggregated link is aggregated by multiple sub-links, its bandwidth is equal to the sum of the aggregated physical link bandwidth, so the aggregated link expands the bandwidth that cannot be achieved by a...
