    abstract =  {This document specifies a composite link framework in MPLS network. A composite link consists of a group of homogenous or non-homogenous links that have the same forward adjacency and can be considered as a single TE link or an IP link in routing. A composite link relies on its component links to carry the traffic over the composite link. The document specifies composite link framework. Applicability is described for a single pair of MPLS-capable nodes, a sequence of MPLS-capable nodes, or a set of layer networks connecting MPLS- capable nodes.},
