label edge router

<networking> (LER) A device that sits at the edge of an {MPLS domain}, that uses routing information to assign labels to datagrams and then forwards them into the MPLS domain. (1999-06-14)

label switched path

<networking> (LSP) The specific path through a network that a datagram follows, based on its MPLS labels. (1999-06-14)

Label Switching Router

<networking> (LSR) A device that typically resides somewhere in the middle of a network and is capable of forwarding datagrams by label switching. In many cases, especially early versions of MPLS networks, a LSR will typically be a modified ATM switch that forwards datagrams based upon a label in the VPI/VCI field. (1999-06-14)

Multiprotocol Label Switching

Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses. Whereas network addresses identify endpoints the labels identify established paths between endpoints. MPLS can encapsulate packets of various network protocols, hence the multiprotocol component of the name. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL.
