Abstract
An OSI layer 2 network device on the edge of a network such as a SAN is configured to replace the original source address of traffic entering the network with a known identifier or address, which is used to signify that entry point as the traffic source to the other nodes of the network. Nodes of the network recognize the new source address as a valid source address. The network device also maintains state (e.g., association of original source address with new source address/identifier) so as to translate addresses to enable reply traffic to be sent back to the original sender.
