Abstract

This document specifies an IP-based encapsulation for MPLS, calledMPLS-in-UDP for situations where UDP (User Datagram Protocol)encapsulation is preferred to direct use of MPLS, e.g., to enableUDP-based ECMP (Equal-Cost Multipath) or link aggregation. The MPLS-in-UDP encapsulation technology must only be deployed within a singlenetwork (with a single network operator) or networks of an adjacentset of cooperating network operators where traffic is managed toavoid congestion, rather than over the Internet where congestioncontrol is required. Usage restrictions apply to MPLS-in-UDP usagefor traffic that is not congestion controlled and to UDP zerochecksum usage with IPv6.
