<p><P>PROBLEM TO BE SOLVED: To reduce a processing load of routing by reducing the number of entries to be held by nodes on a network. <P>SOLUTION: Regarding a network on which traffics of a plurality of services flow, for each service, a logic network on which traffic of the service flows is divided. The logic network is constructed of a tree-shaped topology, and on the basis of layered in a tree of each node and the number of slave nodes present under the relevant node, a value of an address is allocated. Each of nodes on the logic network holds in a routing table a destination address of a packet, an address of the node's own, layer information, parameter information of the logic network to which the node itself belongs, information of a master node and slave nodes of the node's own. On the basis of the routing table, it is determined whether to transfer a received packet to the master node or to the slave node, and when transferring the packet to a slave node, it is determined which one of slave nodes the packet should be transferred to. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
