Abstract
A network appliance is configured to store and retrieve instructions for handling a packet corresponding to a connection. The network appliance includes a connection storing processor configured to hash an incoming flow identifier for incoming packets to obtain an incoming hash; to hash an outgoing flow identifier for outgoing packets to obtain an outgoing hash; to insert an incoming entry corresponding to the incoming hash in a bidirectional hash table; and to insert an outgoing entry corresponding to the outgoing hash in a bidirectional hash table. A connection finding processor is configured to hash a packet identifier to obtain a packet hash; and to determine a matching entry in the bidirectional hash table that corresponds to the packet hash. A memory is configured to store the bidirectional hash table.
