PROBLEM TO BE SOLVED: To allow communication between objects to be performed in a multiprocessing system without taking a communication method or hardware such as a communication route into consideration.SOLUTION: A tree of communication object nodes is configured over the entire multiprocessing system, and nodes other than leaf nodes in an application layer are disposed in a middleware layer to perform packet switching through the nodes in the tree. Each node saves a received packet as a packet addressed to the node if a destination address of a header thereof matches an address of the node, transfers the received packet to a child node if the destination address of the header indicates a child node side of the node, or otherwise, transfers the received packet to a parent node of the node. |
