Communication control system, switch node and communication control method

摘要

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.

1. A communication control system, comprising:
a switch node configured to carry out processing of each of received packets based on a flow entry defining a rule and an action to uniformly control the packets; and a control server configured to set the flow entry into a flow table of the switch node, wherein the switch node comprises:
means for connecting a plurality of processors including large-capacity memories and a plurality of extended network interfaces by a multi-route compatible Peripheral Component Interconnect (PCI) express switch, to configure switch ports including the plurality of extended network interfaces;means for carrying out load distribution transfer processing from the plurality of extended network interfaces to the plurality of processors and carrying out high-speed packet processing through multiple processing by using the plurality of processors;means for configuring a large-capacity flow table in the switch node which is software-based, by using a large-capacity memory space of the plurality of processors;means for receiving the packets by either of the plurality of extended network interfaces; andmeans for determining distribution processing to the plurality of processors by using a hash function in one of the plurality of extended network interfaces which receives the packets, and carrying out high-speed processing through the load distribution processing of software packet processing and multiple processing of the packet processing in the plurality of processors.
