<p><P>PROBLEM TO BE SOLVED: To solve the problem that, on a network for transferring a preferential packet more preferentially than a non-preferential packet, when monitoring bandwidths of preferential packets by a bandwidth monitoring device at the entry of the network while the bandwidth of preferential packets is contracted between a network user and a network provider, if the preferential packets sent by the network user have a bandwidth less than the contracted bandwidth, the network user can not sufficiently utilize the contracted bandwidth. <P>SOLUTION: When a monitoring result determining section 520 detects that the bandwidths of preferential packets is less than the contracted bandwidth by the bandwidth monitoring section 141 of the bandwidth monitoring device, a differentiated service code point (DSCP) determining section 530 determines a non-preferential packet as a preferential packet. Namely, a network transmits non-preferential packets as preferential packets, so that a network user can sufficiently utilize the contracted bandwidth. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
