Abstract 

   Existing technologies to encapsulate Multi-Protocol Label Switching 
   (MPLS) over IP are not adequate for efficient load balancing of MPLS 
   application traffic, such as MPLS-based Layer2 Virtual Private 
   Network (L2VPN) or Layer3 Virtual Private Network (L3VPN) traffic 
   across IP networks. This document specifies additional IP-based 
   encapsulation technology, referred to as MPLS-in-User Datagram 
   Protocol (UDP), which can facilitate the load balancing of MPLS 
   application traffic across IP networks.  

Status of this Memo 

   This Internet-Draft is submitted in full conformance with the
