    abstract =  {This document describes certain optimizations to how entropy labels can be used for load balancing in a seamless MPLS architecture, as enabled by LSP concatenation and LSP hierarchies. The definition of the control plane and data plane behavior at LSP concatenation points; and at the ingress of an LSP in a hierarchy of LSPs, as described in this document, brings the benefits of entropy labels to certain deployment scenarios that may not have had such benefits as specified in {[}EL-RFC{]}. This document, if approved, updates RFC 6790.},
