If Y is present in the ARP cache and is associated with a different interface, the source network-node chooses a winner interface, and updates the ARP cache so that Y is associated with the winner interface. The network-node sends one or more contention-resolution packets on the loser interface to cause a loser network-node to choose another link-local IPv4 address for itself. | 2009-04-09 |
20090092064 | ROUTING SWITCH DETECTING CHANGE IN SESSION IDENTIFIER BEFORE RECONFIGURING ROUTING TABLE - An automatic network topology identification technique is described herein. Each node in the network periodically or constantly transmits its unique address to its neighboring node. Once a node receives a different message from its neighbor, the node identifies a topology change in the network. In one embodiment, a current topology is associated with a session number. When a change in the topology is detected, the detecting node increments the session number and broadcasts the change in topology. The other nodes, detecting the changed session number, now know that there has been a change in the network. In response, the nodes in the network modify routing tables and other information stored at the node related to the topology. In one embodiment, the technique is used to reassign shortened addresses to each device on the network to support a dual-addressing mode of the network. The dual addressing mode substitutes reduced-length addresses (referred to as short addresses) for standard addresses (referred to as long addresses) for traffic whose source or destination is internal to a given virtual network topology. The required length of short addresses used for a given virtual topology is dependent on the number of devices reachable within the topology. | 2009-04-09 |
