Abstract
An address learning technique in a data communication network. A packet may be received by the network system when the ingress equipment does not yet have information to lookup the appropriate path for the packet based upon its destination media access control (MAC) address. The packet may then be broadcast or multicast to all possible or probable destinations for the packet. Each such destination adds an entry to its lookup table using the source MAC address and an identification of the path by which it received the packet. Then, when one of those destinations (acting as ingress equipment) receive a packet intended for that MAC address, it will have the necessary information in its lookup table to send the packet along the appropriate path. Thus, table entries are formed and stored in the remote destinations rather than in the ingress equipment.
