Is there a reason why complete information is in the ENSS rather than the CNSS? My understanding of the agreement is that it is for the benefit of ANSnet and the CIX, so why should the regionals have to adjust the way they are set up? I'm not just saying this to be contrary (Honest). I am really interested in knowing why this method was chosen. As others have pointed out it move the burden of enforcing policy restriction to individual AS pairs. Comments?

Brad, You are correct that our interpretation of the AUP situation is that the burden is on the regionals/midlevels to enforce the policies as they apply to their institutions. This can be done by simply issuing a public statement to all users that people should only use the NSFNET for purposes of research and education. Or it can be done a bit more drastically by filtering out routes. The actual implementation of filters needs to be done in the regional's peer router when default routing is used. Does this help?

It does provide something of a clarification BUT I still have many questions. Does this mean that NSFnet will now take NACRs for any network and we no longer need to claim that people will abide by the AUP? This seems to me to be a radical change in policy. What is the reason for this shift? If people are still bound by the AUP and regionals can not submit NACRs for non AUP sites than it appears to me that we now have two classes of citizens on the Net. Those that can transmit any kind of packet and make the rest of the people bear the burden of preventing traffic we don't want and those of us who can't :-( I can understand that Merit does not want to enforce specific regional access policys *but* the regionals have been able to count on getting traffic that fits a specific AUP requirement from the NSFnet. This is no longer true. Can you tell me how this change benefits the regionals or even NSFnet? Can you tell me why you aren't keeping complete information in the CNSSs instead of the ENSSs? I can't see the problem you are solving by engaging in this activity. Brad Passwaters (301)(982-3214) SURAnet Operations bjp@sura.net <My name, My opinions>
