This document defines basic terminology for describing different
types of Network Address Translation (NAT) behavior when handling
Unicast UDP and also defines a set of requirements that would allow
many applications, such as multimedia communications or online
gaming, to work consistently.  Developing NATs that meet this set of
requirements will greatly increase the likelihood that these
applications will function properly.  This document specifies an Internet

        URL:        http://www.rfc-editor.org/rfc/rfc4721.txt

Mobile IP, as originally specified, defines an authentication
extension (the Mobile-Foreign Authentication extension) by which a
mobile node can authenticate itself to a foreign agent.
Unfortunately, that extension does not provide the foreign agent any
direct guarantee that the protocol is protected from replays and
does not allow for the use of existing techniques (such as Challenge
Handshake Authentication Protocol (CHAP)) for
authenticating portable computer devices.

Protocol Action: 'Extensions to RSVP-TE for Point-to-Multipoint TE LSPs' to Proposed Standard

The IESG has approved the following document:

- 'Extensions to RSVP-TE for Point-to-Multipoint TE LSPs '
   <draft-ietf-mpls-rsvp-te-p2mp-07.txt> as a Proposed Standard

This document is the product of the Multiprotocol Label Switching Working

Group. 

The IESG contact persons are Ross Callon and Bill Fenner.

A URL of this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-mpls-rsvp-te-p2mp-07.txt

Technical Summary

  This document describes extensions to Resource Reservation 
  Protocol - Traffic Engineering (RSVP-TE) for the set up of
  Traffic Engineered (TE) point-to-multipoint (P2MP) Label Switched
  Paths (LSPs) in Multi-Protocol Label Switching (MPLS) and 
  Generalized MPLS (GMPLS) networks.  The solution relies on RSVP-TE 
  without requiring a multicast routing protocol in the Service
  Provider core. Protocol elements and procedures for this solution
  are described.

  There can be various applications for P2MP TE LSPs such as IP
  multicast and multicast over VPNs.  Specification of how such
  applications will use a P2MP TE LSP is outside the scope of this
  document.

I-D ACTION:draft-ietf-l2vpn-oam-req-frmk-07.txt

A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Layer 2 Virtual Private Networks Working Group of the IETF.

	Title		: L2VPN OAM Requirements and Framework
	Author(s)	: D. Mohan, A. Sajassi
	Filename	: draft-ietf-l2vpn-oam-req-frmk-07.txt
	Pages		: 35
	Date		: 2007-2-1
	
This draft provides framework and requirements for Layer 2 Virtual
Private Networks (L2VPN) Operation, Administration and Maintenance
(OAM). The OAM framework is intended to provide OAM layering across
L2VPN services, Pseudo Wires (PWs) and Packet Switched Network (PSN)
tunnels. The requirements are intended to identify OAM requirement
for L2VPN services (i.e. VPLS, VPWS, and IPLS). Furthermore, if
L2VPN services OAM requirements impose specific requirements on PW
OAM and/or PSN OAM, those specific PW and/or PSN OAM requirements
are also identified.
