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： The present invention reduces the number of entries retained in a communication node and reduces the load on a control apparatus in a centralized control network. The communication device comprises a first table that stores a first entry in which a match condition that includes at least a destination address is associated with an output destination of a packet matching the match condition; a second table that stores a second entry having a predetermined match condition; a destination learning unit that registers a set of a source and a receiving port of a received packet as a match condition and an output destination, respectively, in the first table; and a packet processing unit that forwards a packet to an output destination determined in the first table when an entry having a match condition matching a received packet is found from each of the first and second tables. The packet processing unit broadcasts a received packet according to a third entry when no entry having a match condition matching the received packet is found.

摘要： According to the present invention, when an operation at an ingress/egress of a network is implemented as an action resulted from searches of tables, needed action patterns can be reduced, and accommodation of action resources can be expanded. In each of switches, there are provided a plurality of stages of tables including at least a first table and a second table mutually different in mapping of egress information of a network and user information to a packet. Each of the tables is used for searching whether predetermined information of the packet matches a search key of an entry in the table and an operation defined by an action corresponding to the matched search key is performed. The first table is searched for a first packet that has been received. When the search key of the first table is matched, the operation according to the action corresponding to the search key of the first table is applied to the first packet to convert the first packet to a second packet. The second packet is supplied to the second table. The second table is then searched for the second packet. When the search key of the second table is matched, the operation according to the action corresponding to the search key of the second table is applied to the second packet to convert the second packet to a third packet (refer to Fig. 5 ).

摘要： A plurality of switches include first packet forwarding function that processes a packet based on control information set externally, and second packet forwarding function that learns relationship between a transmission source address and a receiving port of a received packet and determines an output port of a packet. A control apparatus comprises: communication unit that communicates with the plurality of switches; control information setting unit that sets control information instructing the first packet forwarding function of the plurality of switches to forward a packet using the second packet forwarding function; path calculation unit that calculates a packet forwarding path based on connection relationship among the plurality of switches; and VLAN setting unit that sets a VLAN ID predetermined for the packet for input/output ports of the packet in a switch(es) on the packet forwarding path. The present invention contributes to facilitating the implementation of a centrally controlled network.
