<P>PROBLEM TO BE SOLVED: To protect the quality of session even when a lot of traffic is generated immediately after disaster, for example. <P>SOLUTION: A rate lower than an acceptable rate is set anew in each link and three regions, i.e., a region where the rate of actual traffic is lower than the rate set anew, a region between the rate set anew and the acceptable rate, and a region higher than the acceptable rate, are not marked, some packets are marked, and all packets are marked so as to represent three regions by the percentage of the mark thus distinguishing three regions without using a new header field. The maximum available band is estimated for each ingress router by an exit router, and the number of new flows per unit time is regulated from the estimate and the use band of a currently pending flow. <P>COPYRIGHT: (C)2013,JPO&INPIT |
