METHOD FOR REDUCING THE REQUIRED MEMORY CAPACITY OF SWITCHES BY USING FICTIVE SOURCE MAC ADDRESSES

摘要

The present invention relates to an access node for an access network. The access node is arranged to receive uplink data packets from a plurality of network devices. Each data packet comprises a source MAC address related to the network device being the source of the data packet. The access node is arranged to alter the source MAC address in the received uplink data packets to a fictive source MAC address common for at least a subset of said network devices. The present invention also relates to a method for controlling data packet traffic in an access node.
