ABSTRACT:
A novel hashing function and hashing collision resolution method are introduced that combine multiple known hashing resolution methods to achieve a very low collision probability that is specifically useful in lookup of long keys, such as (for example) the VLAN and MAC lookup in Ethernet switches. However, the system and method introduced here can be used in any networking and telecommunication systems.
