Abstract
In a switch node connected with an external control server, a high functional service protocol processing can be realized by utilizing a multi-route compatible switch and a network interface (NW I/F), which are prescribed by the PCI express. Specifically, in a system which is provided with a switch node and a control server, a plurality of CPUs having a great deal of memories and a plurality of extended NW I/Fs are connected by a multi-route compatible PCI express switch, to configure a switch port of the plurality of extended NW I/Fs. Load distribution transfer processing to the plurality of CPUs from the network interfaces is made possible. High-speed packet processing is realized through the multiple processing by using the plurality of CPUs. A high-speed switch node is provided in which a large-capacity flow table is configured with the software-based switch node by using a large-capacity memory space of the CPU.
