Technical Summary

This document describes how entropy labels (EL) may be used with
Segment Routing running over an MPLS data plane. Entropy labels (EL)
is a technique used in MPLS to improve load-balancing.
Segment Routing (SR) is a technique  that uses  a source routing paradigm. 
A node (LSR) steers a packets through an ordered list of instructions, called
segments.

Working Group Summary

 There have been no controversies over this document.
