Method, Program and System for Efficiently Hashing Packet Keys into a Firewall Connection Table |
摘要 |
A method for increasing the capacity of a connection table in a firewall accelerator by means of mapping packets in one session with some common security actions into one table entry. For each of five Network Address Translation (NAT) configurations, a hash function is specified. The hash function takes into account which of four possible arrival types a packet at a firewall accelerator may have. When different arrival types of packets in the same session are processed, two or more arrival types may have the same hash value.
