System and method for traffic distribution in a multi-chassis link aggregation

摘要

A pair of aggregation switches is connected to an edge node by a multi-chassis link aggregation group, wherein the aggregation switches are connected by a virtual fabric link (VFL) for exchange of information between the Aggregation Switches. The VFL includes a plurality of subsets of VFL physical links, wherein each subset is connected to a different pair of network interface modules on the Aggregation Switches. Traffic distribution across the plurality of subsets of VFL physical links is based on destination hardware device information in a pre-pended header of packets and/or based on a load balancing identifier in the pre-pended header.
