Abstract
A method and system for fairly adjusting the bandwidth among distributed network elements (NEs). Load-balancing (LB) packets, carrying designated congestion values (CVs) are sent from each source NE to intermediate NEs along data flows routes. The intermediate NEs stamp each received LB packet with a segment CV, if the segment CV is greater than the designated CV, and forward the LB packet to the next NE, until the packet reaches the respective destination NE, which returns it to the source NE. The CV received at each source NE and the state of an associated channel queue are then used to regulate the channel rate to allow the reduction of traffic load in congested network segments.
