In my town, a major manufacturer put in their own SONET rings.

Private discussions of this topic abound. We always come to these observations. My discsusions with others in research and network planning has yeilded similar concerns. I really wonder if anyone really cares about this enough to propose a preliminary service model with the corresponding business Ts & Cs. My belief is that if a wide spread agreement can be reached on the business issues, then the technology-builders will respond rapidly. In the meantime, we will continue to see differentiated quality of service only in: 1. Private network segements (Intranets) 2. L2 supported VPN with ATM QoS 3. Virtual QoS [i.e. over public networks with your fingers crossed] >If the fibre shortage is resolved quickly and all these promised WDM and >optical technologies come to pass than the QoS/CoS business issues may prove >to be an interesting technical challenge but never get wide commercial >deployment. > >Bill I hope that Paul's collections of comments (public and private) will be summarized for this community. However, it would be interesting to see the discussion broadly published in Internet trade press with a clear statement of the issues with a WWW mechanism to reply with a yes-mabey-no statement of interest. I encourage this consumer polling because I do not assume opinions of NANOG readers are representative of opinions in the business market. ..mike..
