<p><P>PROBLEM TO BE SOLVED: To provide a method for managing a standby path band with high utilization efficiency. <P>SOLUTION: When a stanby path is set in a loop shape with a node A as a starting point and as an ending point with respect to an active path 1, with a node B which has first received a Path message of the active path 2 as an origin, a band change request message containing an identifier of the stanby path and a value of a changed band is transferred by once circulating along the stanby path established in the loop shape, thereby changing the band of the stanby path. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
