Abstract
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.
