What is the Role of MPLS in Integrated Multi-Service Access Networks?
The single biggest challenge for service providers is migrating their existing TDM-based access network to one that is optimized for delivering packet-based IP services while still delivering TDM-class voice services. MPLS provides the tools for network operators to manage traffic, implement QoS and provision secure data Virtual Private Networks (VPNs). Until now the majority of work around MPLS has concentrated on solving the backbone traffic engineering problems of large ISPs. The next step is to extend the reach of MPLS to the customer premises in order to enable enhanced QoS and VPN capabilities for delivering integrated voice and data services across packet-based access networks.
