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.
