A memory efficient, 100 Gb/sec MAC classification engine

In this paper, we propose a classification engine employed at Ethernet's MAC Layer which uses an innovative hashing scheme and internal replacement of MAC vendor IDs; the hash based classification engine (HBCE) compacts the MAC address tables and supports extremely high speed decisions. Its very low memory requirements make it a very promising candidate for Ethernet equipments that would need to support classification at data link layer and at multi-Gigabit per second network speeds. Moreover HBCE can also so be used very efficiently in lower-bandwidth wireless environments
