Paper Abstract

A framework for resource management of MPLS label-switched routes (LSRs) over a diffserv Internet domain is described. A `traffic management' problem is formulated in which the LSRs are not statically allocated an amount of bandwidth and buffers per node. A very limited amount of information is passed on to the diffserv nodes about the traffic characteristics and QoS requirements using the LSR. The diffserv node can use this information and on-line queue measurements for dynamic resources (bandwidth and buffer) management. In this general context, a suitable `shaped' weighted round-robin (SWRR) bandwidth scheduling mechanism is specified. Performance and implementation issues are explored for SWRR. Finally, how SWRR can approximate weighted fair queueing is discussed.
