Over the last few years we have spent a considerable amount of effort at SDSC/UCSD to analyze traffic characteristics of wide area networks. While we were able to just scratch the surface with what is doable and useful, particularly for network planning, engineering, and research, we are getting to a point where it would be useful for us to learn what kind of statistics people currently collect, what they are doing with those statistics, and what kind of statistical objects and analysis they think would make their network work better (make it more manageable, planable, or whatever). So, we are interested in finding out for various operational infrastructures in the U.S. as well as the international Internet community, the following questions: (1) what kind of statistics do you collect? (2) how long of a history do you keep? (3) what is the volume of statistics being generated per day/week/month? (4) what are you doing with them in terms of post processing? Just for operational purposes? In depth analysis? Research, e.g., for published papers? (5) what kind of additional statistics and analysis would you find useful for your network? (6) anything else worth mentioning? We would like to compile a list from the submitted responses, for everyone's benefit. Specifically now with the beginning of much more formalization of network engineering and operational groups that have a strong emphasis on real infrastructure, it may be interesting to find out what the statistics and network analysis requirements are for operational environments, and whether some more of our work could be of value to the Internet community. For example, now that the basic fabric is workable, can we pull things together better in some way or another, e.g., by having a better, and perhaps day-to-day operational, understanding of international flows. If you want more details about what we are doing with network analysis and so, drop me a not and I will send you more information. Hans-Werner
