ABSTRACT:
A network switch, configured for performing layer2and layer3switching in an Ethernet (IEEE 802.3) network without blocking of incoming data packets, includes network switch ports, each including a flow module configured for generating a packet signature based on layer3information within a received data packet. The flow module generates first and second hash keys according to a prescribed hashing function upon obtaining first and second portions of layer3information. The flow module combines the first and second hash keys to form the packet signature, and searches an on-chip signature table that indexes addresses of layer3switching entries by entry signatures, where the entry signatures are generated using the same prescribed hashing function on the first and second layer3portions of the layer3switching entries.
