Abstract:
1. A method for sending a network-packet having a packet-source-address and a packet-destination-address, comprising: establishing a route-cache comprising entries containing at least an entry-source-address, an entry-destination-address, and an entry-reference to a network-interface; designating the network-interface with a front-interface; associating the network-interface with a front-interface-IP-address; creating an off-link destination-entry in the route-cache containing an entry-source-address identical to the front-interface IP-address, and a forwarding-address, wherein the off-link destination-entry does not include the packet-destination-address; determining if the packet destination-address is an off-link address; if the packet-destination-address is determined to be an off-link address, then finding in the route-cache the off-link destination-entry having the same source-address as the packet-source-address and having the forwarding-address, wherein finding in the route-cache the off-link source-entry comprises: sending the packet to the forwarding-address via the front-interface.
