Quality of service in BT’s MPLS-VPN platform

Abstract

The multi-protocol label switching virtual private network (MPLS-VPN) is now firmly established as the preferred choice for providing private IP networking services for a very wide range of customer type, from small regional organisations, to large multinational corporations. Quality of service (QoS) is a natural complement to MPLS-VPN technology, enabling multiservice operation, and supporting the increasing drive toward application convergence. BT has recently launched a second-generation QoS scheme for its MPLS-VPN platform that gives unparalleled capability. This paper gives a detailed overview of the principles and mechanisms of differentiated-services QoS, and describes how this is applied in the BT design.
