QoS ROUTING METHOD AND QoS ROUTING APPARATUS
First Claim
1. A QoS routing method for a plurality of node apparatuses which form a logical network to transmit data communicated between user'"'"'s terminals, wherein each of the plurality of node apparatuses carries out steps of:
- discriminating whether or not flows of received data are measurement flows;
measuring communication quality of links connected to the own apparatus using the measurement flows;
determining measurement accuracy of the communication quality of the respective links;
prescribing transmission amounts of the measurement flows to the respective links; and
applying, when the transmission amounts are prescribed, a higher rate to a link which has been determined a lower measurement accuracy.

Abstract
A QoS routing apparatus as a node of a logical network to transmit data communicated between user'"'"'s terminals comprises a relay unit discriminating whether or not flows of received data are measurement flows and transmitting said received data, a quality measurement unit measuring communication quality of links connected the own apparatus using the measurement flows, a quality accuracy setting unit determining measurement accuracy of the communication qualities of the respective links and a path setting unit prescribing transmission amounts of the measurement flows to the respective links. When the path setting unit prescribes the transmission amounts of the measurement flows, it applies a higher rate to a link which has been determined a lower measurement accuracy.
