MPLS
    Multiprotocol Label Switching speeds up network traffic. When forwarding packets, the
        Layer 2 (Switching) label is used to avoid complex destination lookups in the routing table.
        MPLS uses Label Switched Paths (LSPs) to establish the network path. The packet will be
        labeled so that service providers can decide the best way to keep traffic flowing. The
        Multiprotocol Label Switching Transport Profile (MPLS-TP) extensions to MPLS are designed to
        meet service provider requirements and are used as a network layer technology in transport
        networks. MPLS-TP gives service providers a reliable packet-based technology that is based
        on circuit-based transport networking. MPLS-TP is expected to be a low cost level 2
        technology (if the limited profile is implemented in isolation) that will provide QoS,
        end-to-end OAM and protection switching.
