ABSTRACT:
A networking system is disclosed that has an improved address resolution protocol. The network system, which includes a table or cache, has a plurality of nodes, each node having a unique address. The protocol establishes in the table an address mapping for each of the nodes in the network system being used. The protocol generates a target address for an addressing request. When an address mapping needs to be reresolved/refreshed, the protocol then sends the request to the node associated with the address currently in the table. The protocol allows for a certain amount of time for the node to accept the request and then updates the address mapping table based upon a reply received within that limited time. If the node fails to reply within a given time, the protocol then broadcasts the request throughout the networking system until a response is received. Once a response is received, the system then updates the table of address mapping.
