Abstract
A control method and apparatus for distributing packets to nodes in a cluster, while realizing a single system image at the network address level and such as to be able to simply and dynamically change the distribution destination, conditions of distribution, and the like. A pattern matching unit in a relay device receives packets coming from a packet receiving device. The packets have an address which represents a cluster. Using a distribution control table, pattern matching is performed based on the transmission origin address, transmission origin port, destination port and the like of this packet. A hash calculation unit, from the matching result, performs a hash calculation obtaining the argument of a hash function. A destination node extraction unit sets the destination node of the packet based on the hash result, using the distribution control table.
