Beyond The Core: MPLS In Metro, Access And Private Networks

Abstract:

 

The battle for the backbone is over. Multi-protocol Label Switching (MPLS) has conquered the core of most public IP networks. Its label-switched paths (LSPs) are a natural fit for virtual private networks (VPNs). Its quality of service (QOS) and fast-reroute features let service providers sign service-level agreements with confidence. Emerging pseudo-wire standards even let MPLS networks carry non-IP traffic. MPLS is multiprotocol at last.

 

Now MPLS is working its way into metro and access networks and even showing up in some private enterprise networks. What’s driving this expansion? How will it affect existing services like frame relay and ATM (asynchronous transfer mode)? And what happens when metro-MPLS meets metro-Ethernet?
