> All,

> at the mpls wg meeting at the 54th IETF in Yokohama the issue 
> of having
> two functional similar (not to say overlapping) protocols addressing
> the same functional space, as rsvp-te and cr-ldp were brought up.
> 
> The background is that when the signaling protocol for mpls traffic
> engineering and setting up explicit / constraint based routes were
> designed, there were two different approaches. One  based on rsvp and
> the other on ldp. It was not at that time possible to resolve the
> differences between the two approaches and this protocol duplication
> as been reflected in creation of sometimes functional duplicate
> specifications.
> 
> Since then both protocols has been progressed to proposed standard
> and implemented.
> 
> However, as has been shown in the survey on signaling protocols for
> GMPLS the implementations of rsvp-te far out number the cr-ldp
> implementations. As there are issues with having two similar standards
> (potentially diverging), and it generates duplicate work in several
> ietf working groups, the question was asked whether we should make
> cr-ldp informational (which still make it available and possible to
> work with) and progress only rsvp-te on the standards track.
> 
> At the meeting there were a wide spread support for this idea, but
> it was ruled that it was premature to call wg consensus on this at the
> meeting and that we wanted to take the discussion on the mpls mailing
> list.
> 
> This mail is to initiate this discussion. Please keep the discussion
> on the mpls list, do not cross post other lists. A separate mail to
> the ccamp, pwe3 and ppvpn has been sent to inform those wg's of this
> discussion.
