Traffic forwarding method and system based on virtual switch cluster

A traffic forwarding system based on a virtual switch cluster, comprising a setting module, a traffic monitoring module, a traffic sharing module and a traffic forwarding module;

• wherein
• the setting module is configured to set an aggregation group member list and an aggregation group traffic forwarding member list;
• wherein the aggregation group member list stores information of all members of an aggregation group, the aggregation group traffic forwarding member list stores information of members of the aggregation group member for forwarding traffic of a physical device, and the aggregation group traffic forwarding member list in an initial state only contains information of local members of the aggregation group;
• the traffic monitoring module is configured to determine traffic of the physical device in the virtual switch cluster;
• the traffic sharing module is configured to, when traffic of the physical device exceeds total bandwidth of members in the aggregation group traffic forwarding member list corresponding to the physical device or a threshold value related to the total bandwidth of the members in the aggregation group traffic forwarding member list, select a nonlocal member from the aggregation group member list and add the selected nonlocal member into the aggregation group traffic forwarding member list;
• and
• the traffic forwarding module is configured to forward traffic according to the aggregation group traffic forwarding member list that has been changed.
