摘要： In a network system in which a switch forwarding packets and a control server determining route information are separated, it is desired to achieve a redundancy of the control channel by an out-of-band control channel and an in-band control channel, when the switch receives a control message regarding the flow entry registration and the like based on the route information from the control server. Specifically, the separated switch and control server are connected by a control channel for sending and receiving the control message. The switch is not only connected to a control server via an out-of-band control channel by a route dedicated to the control message, but also connected to another control server via an in-band control channel by a route which is common with a normal data communication for determining the route information, to achieve a redundancy of the control channel.

摘要： A switch device is composed of a switch portion 1-1, input side port mapping blocks 1-4-1 to 1-4-P, output side port mapping blocks 1-5-1 to 1-5-P, and a virtualization controller (central controller) 1-0 so that the switch device can be logically divided into a plurality of switches each having a capacity smaller than a physical switch capacity or the divided switches can be logically integrated. The switch portion has a plurality of first input ports and a plurality of first output ports. Each of the input side port mapping blocks has a plurality of second input ports and inputs the signals input to the plurality of second input ports to the first input ports of the switch portion. Each of the output side port mapping blocks has a plurality of second output ports and outputs the signals output to the first output ports of the switch portion from the plurality of second output ports.

摘要： A switch (304) includes a plurality of bridges (3041, 3042, 3043, 3044, 3045) and a switch forwarding mechanism (20). Each of the bridges transmits and receives a TLP frame complying with PCI express to and from a device connected to each of the bridges. The switch forwarding mechanism includes a plurality of ports (1, 2, 3, 4, 5) to which the bridges are connected, respectively, selects an output port in dependence on a combination of destination information on the TLP frame input from one of the plurality of ports and the port which input the TLP frame, and outputs the TLP frame from the selected output port.
