Multiprotocol Label Switching( MPLS)

Multiprotocol Label Switching (MPLS) is a protocol for speeding up and shaping network traffic flows.  

MPLS allows most packets to be forwarded at Layer 2 (the switching level) rather than having to be passed up to Layer 3 (the routing level). Each packet gets labeled on entry into the service provider's network by theingress router. All the subsequent routing switches perform packet forwarding based only on those labels—they never look as far as the IP header. Finally, the egress router removes the label(s) and forwards the original IP packet toward its final destination. 

The label determines which pre-determined path the packet will follow. The paths, which are calledlabel-switched paths (LSPs), allow service providers to decide ahead of time what will be the best way for certain types of traffic to flow within a private or public network.

Service providers can use MPLS to improve quality of service (QoS) by defining LSPs that can meet specific service level agreements(SLAs) on traffic latency, jitter, packet loss and downtime. For example, a network might have three service levels -- one level for voice, one level for time-sensitive traffic and one level for “best effort” traffic. MPLS also supports traffic separation and the creation ofvirtual private networks (VPNs) virtual private LAN services (VPLS) andvirtual leased lines (VLLs).
