Method and device for extending inter-cluster aggregation group member ports

Abstract

The present invention discloses a method and equipment for extending members of an inter-cluster aggregation group: each device in the cluster receives the message sent by the main control board to join the aggregation group; a certain device determines that the port to be added to the aggregation group is The first port on the device to be added to the aggregation group, and this port is the first port to be added to the aggregation group, add the port to be added to the aggregation group. By applying the method and device for expanding members of an inter-cluster aggregation group described in the present invention, the number of member links in the aggregation links between cluster devices can be increased, and the robustness of inter-cluster network interconnection can be enhanced.

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
