For providing a technology capable of balancing a CPU load and a network load independently, a distributed processing system includes one or more distributed processing devices in a structured P2P network, and the distributed processing device is provided with a key holding means for holding a routing key which is a key (value) for which order relation is defined and used for routing data, and an event key which a key (value) for which order relation is defined with relation to the routing key, and is used for management of data; a distributed processing device initializing means for registering into a routing table a tuple including the event key and an address of the distributed processing device holding the routing key which has a predetermined relation with the routing key held in the key holding means; and a routing table storing means for storing the routing table holding the tuple.
