Inter-Domain LSP Setup Using Bandwidth Management Points

Free registration required

Executive Summary

Bandwidth Management Points (BMP) are a necessity to manage the intra and inter-domain resources in the Internet. In this paper the authors propose a way to setup inter-domain Label Switched Path (LSP) with the help of a BMP in a MultiProtocol Label Switching (MPLS) over Diff-serv network. They use extended Simple Inter-domain Bandwidth Broker Signaling Protocol (SIBBS) to distribute the labels inter-domain. They also use a BMP to interact with the MPLS to setup the intra-domain LSP and to provision the intra-domain traffic. With the help of a BMP, they show how end-to-end Quality of Service (QoS) can be achieved.
