BAND MEASURING METHOD FOR PACKET COMMUNICATION NETWORK, BAND MEASURING INSTRUMENT AND BAND MEASURING PROGRAM, AND SENDING-OUT SPEED CONTROL METHOD, SENDING-OUT SPEED CONTROL UNIT AND SENDING-OUT SPEED CONTROL PROGRAM FOR PACKET

摘要

PROBLEM TO BE SOLVED: To lighten the load of band measuring operation on a communication network by reducing unnecessary band measuring operation.;SOLUTION: A band measuring method uses, in combination, a band measuring function of measuring an effective band of a packet communication network by sending out a packet for band measurement from a transmission side to a reception side through the packet communication network and a line monitoring function of monitoring the state of the packet communication network with a smaller load on the packet communication network than the band measuring function by sending out a packet for line monitoring from the transmission side to the reception side through the packet communication network. Namely, monitoring by the line monitoring function is intermittently carried out and it is judged whether band measurement by the band measuring function is performed according to the monitoring result of the line monitoring function.;COPYRIGHT: (C)2008,JPO&INPIT
