Abstract
A packet distribution scheme for forwarding incoming packets to servers in a network. Depending on a hash value of the incoming flow's identification parameters, a hash flow table or database is queried to determine the server to which the packet is to be forwarded. If multiple flows have the same hash index and are associated with different servers, a secondary flow table or database is queried for determining the server. In an example implementation, only the secondary flow table is configured to store fully qualified flow identification parameters whereas the hash flow table is operative to store reduced or compressed state information.
