A System for Weighted Max-Min Congestion Control in MPLS Networks

This paper introduces a framework to support explicit rate congestion control for besteffort service inMPLSnetworks.We devise the two basic mechanisms required, namely, a signaling component to convey explicit-rate congestion control information and associated algorithm for calculating explicit fair rates. The proposed signaling component uses Resource Reservation Protocol (RSVP) in a novel way to convey explicit rate congestion control information. An algorithm to calculate Weight Proportional Max- Min (WPMM) fair rates appropriate forMPLS networks is introduced. Simulations are presented that show the effectiveness of the RSVP explicit rate signaling method when combined with the proposed max-min fair rate algorithm.
