摘要： A switch system allows free change of a grain degree of monitoring without being conscious of a routing control. For example, a control protocol of a transmitter is used based on the open flow (OpenFlow) technique to control the monitoring function of the switch system, and the centralized control of the monitoring can be realized as the whole network and the monitoring result is reflected on the routing control. Here, the switch has a flow table for packet transfer and a flow table for monitoring. Both of the tables are searched to one packet and a multi-hit operation is performed to execute the operation of each of the entries. That is, both the tables are searched and the packet is transferred according to corresponding flow entries.

摘要： A switch system realizes extension of the number of entries of an open flow table by using tables in a switch as existing resources. Specifically, the switch configures an open flow table by logically combining a plurality of tables, each of which defines processing to a given packet, based on a condition and a processing content defined in each table. The switch refers to the open flow table to determine the processing content to a reception packet. The switch executes the processing of the reception packet based on the determined processing content.

摘要： In a switching node, high-speed and advanced service protocol processing function is achieved by utilizing an external control server without affecting performance of conventional service protocol processing. Specifically, a forwarding engine has PCI express and an LAN interface. Depending on a type of an input packet, destination of the packet is switched to the PCI express side for conventional network service and to the LAN interface side for extended network service that cooperates with the external control server. A CPU having the PCI express and the LAN interface is provided ahead of the LAN interface. The CPU performs communication of service inquiry with the external control server at high speed via the LAN interface. After response from the control server is obtained, setting of the forwarding engine is performed through the PCI express.

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： In the case of a system where a communication device is remote-controlled from a control server, depending on timing when an entry is written into a forwarding table of the communication device from the control server, there is a possibility that a loop and discard of the traffic occur. Therefore, for registration, rewriting and deletion of the entry of the forwarding table which are performed on the communication device 102 by the control server 101; the communication device 102 verifies contents of control instructions from the control server 101; the communication device 102 holds the result of this verification; the control server 101 acquires the result of the verification; the control server 101 judges whether or not a series of controls can be executed based on the results of the verification from the plurality of communication devices 102; and then the control server 101 invokes the execution at the plurality of communication devices 102.
