Subject: Bundling resolution

Hello, 

There was a heated debate a while ago about bundling,
specifically, pitting draft-kompella-mpls-bundling....
vs draft-rs-optical-bundling-.... As I suspected, there
was not much feedback from anyone other than the
authors (and a couple of other public-spirited souls).

In the trailing end of those discussions, I had pointed
out that if LMP (the link management protocol that
would presumably run under OSPF) can maintain a 
single control channel per multiple bundles, it would
achieve effectively the same effect accomplished by
link groups in our drafts. The present version of LMP
doesn't support this. However, the LMP authors are
working on supporting this feature. With this feature,
the bundling structure proposed in draft-kompella-mpls...
will be more acceptable to us.  The parameter encodings
in this draft are still a bit convoluted (from an optical networking
point of view), and if there is any residual energy,
we might bring this up for discussion later. 

The original intent of our document was both to
indicate how to create bundles in an optical network
with SRLGs, as well as to propose a structure that
kept a single adjacency between neighbors with multiple
links (or link groups) between them. We'll re-issue our
draft to show how all the mechanisms
presently in the works (bundling, LMP, OSPF extensions, etc)
should be used to achieve the above objectives in the optical network 
context. 

Regards,

Bala
