Title : Multi-Segment Pseudowire Setup and Maintenance using LDP
Author(s) : F. Balus, et al.
Filename : draft-balus-mh-pw-control-protocol-01.txt
Pages : 18

[MH PWE3 Requirements] describes the requirements to allow a service
provider to extend the reach of pseudo-wires across multiple
domains. A Multi-Segment PW is defined as a set of two or more
contiguous PW segments that behave and function as a single point-
to-point PW.
The current specification of the PW Architecture [PW ARCH] defines
the PW as a single Segment entity, connecting the Attachment
Circuits between two Ultimate PEs (U-PE). The current procedures for
establishing a single segment PW (SS-PW) is described in [PW
Control], where typically an LDP session is established between the
ultimate PEs handling the Pseudowire End Service (PWES). No
intermediate nodes, between the PEs, are aware of the PW.
The purpose of this draft is to specify new LDP extensions, end to
end signaling procedures to address the related requirements
specified in [MS-PWE3 Requirements]. The proposed procedures follow
the guidelines defined in [RFC3036bis] and enable the usage of
addressing schemes (L2FECs) and other TLVs already defined for PWs
in [PW Control].

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
