Abstract

A flow dubious of an abnormal flow is asked to be specified and flow statistic information of the flow is required to be collected. To comply with such a request, a discard information analyzer of apparatus administrator, for instance, analyzes the number of discard packets, the number of receiving packets or the number of transmitting packets counted by a bandwidth monitor of packet receiver or a bandwidth controller of packet transmitter and in accordance with the result of analysis, automatically sets, in an OUT side flow controller or In side flow controller, information for identifying a flow subject to flow control. Further, the OUT side flow controller or IN side flow controller picks flow statistic information from packets belonging to the object flow by using the set flow identification information.

Description

technical field [0001] The present invention relates to information relay technology, in particular to an effective technology applicable to information relay devices such as routers and LAN switches. Background technique [0002] For example, an information relay device such as a router or a LAN switch determines the sending route of the data packet based on the address for Internet in the received data packet and the route information table stored in the information relay device, and sends the data packet. [0003] In recent years, as a connection network to the Internet, public networks or access networks (such as regional IP networks, etc.) provided by communication operators (such as ISP (Internet Service Provider), etc.) are shifting from private networks to broadband Ethernet (R), The traffic of data packets or the number of users utilizing the access network increases significantly. The information relay device has a function of increasing the number of accommodated...
