Abstract:
1. A method for sharing data link layer information of network traffic distributed across a cluster of intermediary devices, the method comprising: (a) receiving, by a first intermediary device of a cluster comprising a plurality of intermediary devices, a transport layer packet; (b) identifying, by the first intermediary device, a first set of data link layer information from a data link layer of the transport layer packet; (c) modifying, by the first intermediary device, the transport layer packet for transmission on a common data backplane of the cluster to include the first set of data link layer information in the transport layer packet and to replace, at the data link layer, the first set of data link layer information with a second set of data link layer information different from the first set of data link layer information, the second set of data link layer information identifying, as a source Media Access Control (MAC) id, a Media Access Control (MAC) id comprising a cluster identifier identifying the cluster and a node identifier identifying the first intermediary device; and (d) transmitting, by the first intermediary device, the modified transport layer packet on the common data backplane of the cluster to each of the other intermediary devices of the cluster.
