                       draft-ietf-mpls-in-udp-07

Abstract

   This document specifies an IP-based encapsulation for MPLS, called
   MPLS-in-UDP (User Datagram Protocol).  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
   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 by using some
   special field in the encapsulation header as an entropy field.
