Hi Deepak and Vicky, I can't resist comment even though at this point the additional questions that i can answer are very limited. For the past month I have been talking privately and more recently on a private mail list with folk at the heart of this. Canarie under Bill St Arnaud has been the global leader for more than the past five years. Tom Defanti and Joe Mambretti in chicago with the start tap and star light exchanges have been before National lambda rail (NRL) the main players in the US. NRL is perceived as quite important in that it will permit american universities to experiment with their own fiber and wavelength as the canadians have been with CA*Net4 for years. In Europe Kees neggers with Surfnet6 is doing the same thing. As I understand it Internet 2 and Dante/Geant in europe are primarily carrier dependent and therefore for the most part onlookers. NLR, Surfnet6, Ca*Net4 are or will be experimenting with User controlled light paths (UCLP). For more put UCLP in google. I interviewed Bill St Arnaud 2 weeks ago on UCLP. Here one of the purposes is to enable users at the edge to make connection oriented links between each other WITHOUT A CARRIER IN THE MIDDLE by partitioning a segment of a switch or switches between them. The concept is peer to peer and ad hoc. the goal is enabling customer owned and operated networks. As one of the players said on November 15th: "UCLP is simply a layer 1 provisioning and configuration tool. Although we use lightpaths it is not restricted to optical networks. Although it seems paradoxical I am not a big believer in AON, ASON or optical networking in general. I think the big benefit of DWDM networks will be to increase the richness of meshing of IP networks and to allow new business models of IP networking to evolve e.g customer owned and managed IP networks." Web services is being used to set up the lightpaths. If there is sonet underneath the folk with access to webservices can groom the light path from a ds3 on up and with further software development can groom less than a ds3. This stuff is not yet well understood outside these research network circles. I believe that it is hugely important and I will be devoting most of my time in december and january to explaining to a broader audience what these folk are doing. to the world of the best effort public internet it is utterly ALIEN. but my understanding is that it works. NOW. That it is a walled garden and that a big unknown is how long it will remain a walled garden. Hmmm. Maybe I need to be a little more explicit in my concerns.... -- ============================================================= The COOK Report on Internet Protocol, 431 Greenway Ave, Ewing, NJ 08618 USA 609 882-2572 (PSTN) 415 651-4147 (Lingo) [email protected] Subscription info: http://cookreport.com/subscriptions.shtml Worldcall to use ISDN interconnec- tion to offer equivalent of ILEC UNE platform at: http://cookreport.com/13.09.shtml =============================================================
