Problems solved by technology

The following algorithms are used: loop detection algorithm, which uses the polling method to evenly distribute the traffic to each port, but its disadvantage is that a small amount of data packet timing may be confused at the receiving end; adaptive algorithm, the maximum possible The traffic is evenly distributed to each port, and the calculation amount is relatively large; the static algorithm can ensure that each data packet can correctly reach the designated port, but it lacks flexibility and the speed is relatively slow
[0013] In practical application, the above solution has the following problems: the existing link aggregation method has high implementation complexity, high cost, low resource utilization, inflexible configuration, slow processing speed, and cannot conveniently realize stack aggregation

Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] The present invention adopts the port attribute table, the aggregation group table and the aggregation mapping table to realize the management and configuration of the link, the aggregation group and the mapping relationship between them; and according to the link aggregation standard, the configuration method and the aggregation forwarding rule of each table are designed and processing flow, realize the load balancing mechanism, and evenly distribute network traffic on the aggregated links; at the same time, simply realize the stacking link aggregation on this basis.

[0059] In an embodiment of the present invention, the link aggregation is called Trunking, and the aggregation group is called a Trunk group. Since a link corresponds to a port of a switch, ...

Abstract

This invention relates to data communication field and discloses one Ethernet linkage polymer method to realize linkage polymer with low complexity with flexible matching. The invention sets the relative data to terminal property list, Trunk list, Trunk mapping list to process transfer of message to realize linkage polymer and load even through HASH method to realize overlap polymer.

Description

technical field [0001] The invention relates to the field of data communication, in particular to the aggregation technology of communication links. Background technique [0002] At present, no matter on the enterprise network, campus network or WAN such as the Internet, the development of business volume has exceeded the most optimistic estimate in the past, the number of network users is increasing rapidly, and application services are emerging in an endless stream. This makes the current network facilities and other resources unable to meet the rapidly increasing user needs. Especially in the core part of the network, its data traffic and computing intensity are so large that a single device cannot bear it. Therefore, how to achieve reasonable traffic distribution and collaborative operation among multiple network devices that perform the same function, increase network capacity, and maintain balanced operation of each device at the same time has become one of the key te...
