Satish,
The
CSPF is one of the few things that distinguishes different system vendor or
network planning tool
vendor offerings from one another. As such, it is unlikely that there
would be a move to standardize it.
The
CSPF (especially an off-line version) could, for example, use information
beyond what is provided
by
either RSVP-TE or OSPF-TE.
The
basic idea of what a CSPF module/process should expect from OSPF-TE and
RSVP-TE is
clear (the bandwidth parameters and, of course, topology, from
OSPF-TE, and from RSVP-TE those
reserved resources that alter the
bandwidth parameters of links), but I am not aware of any _draft or standards
work_
that
delves into details of these.
If
there is some such work, I'd be interested in knowing about it
too.

Hi All,
I was curious to find out if any work has been
done towards standardizing CSPF (Constrained Shortest Path
First) related issues. At least a framework on what a typical CSPF
module should expect from say OSPF-TE, REVP-TE or may be even RSVP-TE or
OSPF modules taking CSPF algorithms or algorithm classes (in the literature)
into account. What will CSPF do (or may not do) to LMP and vice versa
etc??
I am aware of a draft on the nature of
constraints by Kompella et al, Any thing else apart from
that???
Thanks a lot

Satish Jamadagni.
