ABSTRACT:
One embodiment of the invention provides a method of handling an incoming packet at a node in a network. The method includes associating at least one source identifier with a link into the node. A packet is then received at the node over the link, and a source identifier is extracted from the received packet. The extracted source identifier is compared with the source identifier(s) associated with the link in order to authenticate the packet.
