Encapsulating MPLS in UDP
draft-ietf-mpls-in-udp-01
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
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."
This Internet-Draft will expire on September 30, 2013.
