Layered Service Provider. Layered Service Provider (LSP) is a deprecated feature of the Microsoft Windows Winsock 2 Service Provider Interface (SPI). A Layered Service Provider is a DLL that uses Winsock APIs to attempt to insert itself into the TCP/IP protocol stack.
MPLS uses a variety of protocols to establish Label Switched Paths (LSP) across the network. LSPs are almost like Frame Relay or asynchronous transfer mode (ATM) permanent virtual circuit (PVC), with two major differences: they are unidirectional and they can merge (all LSPs toward the same egress router could merge somewhere in the network).
