Abstract

This paper addresses the requirements and issues surrounding the carriage of existing and future services over a multi-protocol label switching (MPLS) core network. It provides an overview of MPLS, describing how MPLS is already being used to support VPN services offering support for multiple qualities of service. It discusses the requirements of future core networks and assesses how MPLS can be used to meet them. Finally it identifies a number of areas where BT is actively working to enhance the capability of MPLS to support future multiservice core network architectures.
