Method and device for expanding member ports of aggregation groups among clusters

Abstract

The invention discloses a method and a device for expanding members of aggregation groups among clusters. The method includes that each device in a certain cluster receives information that a port is about to be added in a corresponding aggregation group, and the information is issued by a master control board; and when a certain device determines that the port about to be added into the certain aggregation group is a first port about to be added into the aggregation group on the certain device the port about to be added into the certain aggregation group is added into the aggregation group. The method and the device for expanding the members of the aggregation groups among the clusters have the advantages that the quantity of member links in aggregation links among the devices of the clusters can be increased, and the robustness of network interconnection among the clusters is improved.

Description

technical field [0001] The present invention relates to the technical field of aggregation link processing, in particular to a method and equipment for extending member ports of an inter-cluster aggregation group. Background technique [0002] figure 1 It is a schematic structural diagram of aggregated links between existing devices, such as figure 1 As shown in the figure, device A and device B are connected through an aggregated link, and data traffic reaches the opposite end through a member link in the aggregated link in a load-sharing manner. When one of the member links fails, the other The carried data traffic is automatically switched to other remaining member links, and load sharing is performed among the remaining member links. [0003] At present, the aggregation link technology is also used in such as figure 2 In the inter-cluster shown, however, the number of member links in the aggregation link of the cluster is strictly limited by the capability of the har...

Problems solved by technology

[0003] At present, the aggregation link technology is also used in such as figure 2 In the inter-cluster shown, however, the number of member links in the aggregation link of the cluster is strictly limited by the capability of the hardware chip in the device (that is, the number of member ports that can be added to the aggregation group allowed by the hardware chip), if the cluster The maximum number of ports that a certain device can provide is N, and the maximum number of member links in the aggregated link between cluster A and cluster B is N, which cannot achieve the ideal 4*N
