Abstract
A system and method of transmitting data across a first link aggregation formed by an intermediate switch and a downstream switch, the intermediate switch adopting a Media-Access Card (MAC)-address-based load sharing algorithm for distributing traffic among links to the downstream switch interfaced with a final destination device. The method comprises: receiving a packet having a MAC header and an IP header at an input port of an upstream switch for transmission from the upstream switch to the intermediate switch, the upstream switch and intermediate switch forming a second link aggregation; re-writing, at the upstream switch, the source MAC address of the received packet to a different source address; sending the packet through the second link aggregation to the intermediate switch, the intermediate switch implementing the load sharing algorithm for sending the packet to the downstream switch along a link through the first link aggregation to the destination device.
