Re: [PWE3] New Version Notification for draft-cao-pwe3-mpls-tp-pw-over-bidir-lsp-03.txt

[Mach Chen <[e-mail]>]

Hi,

We submitted an update for the explicit PW to PSN binding draft( http://tools.ietf.org/id/draft-cao-pwe3-mpls-tp-pw-over-bidir-lsp-03.txt ), which is mainly based on the comments received during the polling. We'd appreciate that you could review the draft and give your comments!

Many thanks,
Mach

> Abstract:
>    A bidirectional Pseudowire (PW) service currently uses two
>    unidirectional PWs each carried over a unidirectional LSP.  Each end
>    point of a PW or segment of multi-segment PW (MS-PW) independently
>    selects the LSP to use to carry the PW for which it is the head end.
> 
>    Some transport services may require that bidirectional PW traffic
>    follows the same paths through the network in both directions.
>    Therefore, PWs may be required to use LSP with congruent paths.
>    Bidirectional LSPs or co-routed associated unidirectional LSPs allow
>    this service to be provided.
> 
>    This document specifies an optional extension to LDP that allows both
>    ends of a PW (or segment of a MS-PW) to select and bind to the same
>    bidirectional LSP (or co-routed unidirectional LSPs).
