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 : VPLS Applicability
Author(s) : M. Lasserre, et al.
Filename : draft-ietf-l2vpn-vpls-ldp-applic-00.txt
Pages : 20

Virtual Private LAN Service (VPLS) is a layer 2 VPN service that
provides multipoint connectivity in the form of an Ethernet emulated
LAN, while usual L2 VPN services are typically point-to-point. Such
emulated LANs can span across metropolitan area networks as well as
wide area networks.
[VPLS-LDP] defines a method for signaling MPLS connections between
member PEs of a VPN and a method for forwarding Ethernet frames over
such connections. This document describes the applicability of such
procedures to provide VPLS services.
This document also compares the characteristics of this solution
against the requirements specified in [L2VPN-REQ]. In summary, there
are no architectural limitations to prevent the requirements from
being met. But meeting certain requirements (e.g. QoS) is beyond
the specification of [VPLS-LDP], and requires careful planning and
precise implementation of the Service Provider (SP) networks. This
document attempts to capture such issues, presents the potential
solutions to these issues, and discusses the pros and cons of each
alternative.
This document does not cover the applicability of [VPLS-BGP].

In the body type:
"FILE /internet-drafts/draft-ietf-l2vpn-vpls-ldp-applic-00.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
