System and method for transport control protocol in a multi-chassis domain

摘要

Aggregation switches connected to an edge node by a multi-chassis link aggregation group, wherein the aggregation switches are connected by a virtual fiber link that provides a connection for exchange of information between the Aggregation Switches regarding MAC addressing to synchronize MAC address tables. A transport control protocol defines a VLAN and multicast group of ports on the Aggregation Switch to receive management or control packets.

1. An aggregation switch in a multi-chassis system, comprising:
a virtual fiber link connected to a remote aggregation switch, wherein the remote aggregation switch is in a separate physical chassis; a first designated network interface module having a first designated processing module for processing protocol packets, wherein the first designated network interface module is operable to:
generate a protocol packet with a pre-pended header, wherein the pre-pended header includes source hardware device information associated with the aggregation switch and a destination address for a multicast group of a plurality of specific ports in the aggregation switch and the remote aggregation switch, wherein the multicast group includes at least a first processing module port for the first designated processing module and a second processing module port for a second designated processing module for processing protocol packets in a second designated network interface module in the remote aggregation switch; andtransmit the protocol packet with the pre-pended header to the plurality of specific ports in the remote aggregation switch over the virtual fiber link and to the plurality of specific ports in the aggregation switch.
