In the context of GMPLS, LMP stands for:

A.
Load Management Protocol

B.
Label Management Protocol

C.
Loop Management Protocol

D.
Link Management Protocol

Explanation:
The Generalized Multi-Protocol Label Switching (GMPLS)[1] is a protocol suite extending MPLS to
manage further classes of interfaces and switching technologies other than packet interfaces and
switching, such as time division multiplex, layer-2 switch, wavelength switch and fiber-switch.
GMPLS is composed of three main protocols:
Resource Reservation Protocol with Traffic Engineering extensions (RSVP-TE) signaling
protocol.[5][6]Open Shortest Path First with Traffic Engineering extensions (OSPF-TE) routing
protocol.[7][8] Link Management Protocol (LMP).[9]
