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.
