1. Introduction 

   This document specifies an IP-based encapsulation for MPLS, i.e. 
   MPLS-in-UDP (User Datagram Protocol), which is applicable in some 
   circumstances where IP-based encapsulation for MPLS is required and 
   further fine-grained load balancing of MPLS packets over IP 
   networks over Equal Cost Multi-Path (ECMP) and/or Link Aggregation 
   Groups (LAG) is required as well. There are already IP-based 
   encapsulations for MPLS that allow for fine-grained load balancing 
   by using some special field in the encapsulation header as an 
   entropy field. However, MPLS-in-UDP can be advantageous since some 
   networks have used the UDP port number fields as a basis for load-
   balancing solutions for some time. This is similar to why LISP [RFC
