PROBLEM TO BE SOLVED: To process an input message always at any one of nodes in one group at least, to promote forward transfer and to avoid dead lock by classifying the message according to its processing request and message communication protocol and allocating reserved allocation amounts in a message communication buffer to the messages of respective types. SOLUTION: A network message is moved from an output queue 204A or 204B through an interconnect 104 to an input queue 202A or 202B. When transferring a message ReqBA602 and message ReqAB604 between nodes 102A and 102B, a buffer area holding these messages is modeled by the queue of these messages. When the destination node 102A or 102B is turned into block state and the input message can not be processed any more, each input queue 202A or 202B is started being filled and finally, the message is moved back to the output queue 204B or 204A. |
