Abstract:
In order to balance loads and ensure redundancy over an entire network and to balance loads and ensure redundancy at specific links, a communication system is provided with: multiple nodes provided with a packet processing unit that processes received packets in accordance with processing rules obtained by associating processes to be applied to packets and comparison rules for identifying packets to which the processes are to be applied; a trunk port management unit that manages trunked links in the network containing the nodes; and a route control unit which, in accordance with the characteristics of a packet for which processing rule settings have been requested from a given node, determines whether to use the trunked links, and if the trunked links are to be used, selects a trunked link according to a predetermined rule. The control device calculates a packet transfer route that includes the selected link, and sets a processing rule that achieves the packet transfer route in relation to the nodes on the packet transfer route.
