Of course I assume this is only R&E traffic. PSI believe that NSFNet is carrying the traffic of Alternet, PSINet, CERFNet, and other commercial networks like NEARNet and BARRNET, (as measured by type of participants). We are extremely greatful for the evenhanded manner that NSF has been in granting interconnection to the NSFNet for the purposes of carrying R&E traffic as generated by academic, non-profit, and commercial participants of PSINet. > We are working very closely with the NEARNet people to improve their > reliability.

The T3 NSFNet as reported on the Merit/NSR mailing lists from day one has had a tremendous amount of operational difficulties, those difficulties have extended through this week. They are in no way restricted to hopcount/TTL issues, due to T3/T1 interconnect problems - again, as reported by the mailing lists. These difficulties appear to be an order of magnitude more than on the T1 NSFNet, which itself maybe an order of magnitude less stable than most of the commercial networks and regionals - this is possibly due to its non-colocation and factors which have never been under anyone's control - including yours. One of the questions that I have heard from a number of parties is "should the NSF be refunded for the T3 service it is buying?" and "I hope they aren't paying for this yet.". I think this is too strong considering the rollout of something so new under the sun that it has to use proprietary technologies and non-commercial equipment - though the adoption of commercial cisco software is heartening to many. However, the concept of a refund is by some not as ludicrous as you make it out to be. Not having the presentation in front of me this moment I believe Peter Ford's NREN presentation talked about things like acceptance procedures, and standards of delivery or something like that. Clearly these are important factors in post-NSFNet government procurements for internetworking service given the experiences of the past throughout the various pieces of government sponsored networking, whether regional, backbone, or campus.
