Abstract 

   This document specifies an IP-based encapsulation for MPLS, called 
   MPLS-in-UDP (User Datagram Protocol). Note that the MPLS-in-UDP 
   encapsulation technology MUST only be deployed within a service 
   provider network or networks of an adjacent set of co-operating 
   service providers where the congestion control is not a concern.

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
