I got one off-line comment "this work looks good to me and seems somewhat over due..." Given all the experts on this topic in the MPLS WG & RTGWG, it's a bit surprising there hasn't been more response. Not that long ago this topic would probably have generated strong reaction. > > Cheers > Marla > > > > ------------------------------------------------------------------------------ > From: rtgwg-bounces@ietf.org [mailto:rtgwg-bounces@ietf.org] On Behalf Of > Gerald Ash > Sent: Thursday, May 26, 2011 9:51 AM > To: rtgwg@ietf.org > Cc: mpls@ietf.org > Subject: Generic Connection Admission Control (GCAC) Algorithm > Specification for IP/MPLS Networks > > > Hi, > > Adrian has suggested that the RTGWG and the MPLS WG review the draft > "Generic Connection Admission Control (GCAC) Algorithm Specification for > IP/MPLS Networks", available at > http://www.ietf.org/id/draft-ash-gcac-algorithm-spec-00.txt (abstract > below). > > The underlying goal of the work is to specify an optional GCAC > algorithm for IP/MPLS networks, to be adopted and implemented by vendors and > service providers, that interoperates between vendor equipment and across > multiple service provider domains.
