writing up successes. Accordingly, it would be useful to convene an “autopsy workshop” from time to time, perhaps even annually, devoted to learning from past history, at both the individual solution level and the larger research areas level. Documenting negative results will help avoid wasted effort (the reinvention of faulty wheels). A postmortem on larger research areas will help to guide future research by increasing understanding of the specific successes and failures, as well as the underlying reasons for them (economics, for example, or politics). Within research areas, the successes and failures of interest include attempts at disruption to conventional networking, which so far have met with mixed success. Two initial candidates suggested by discussions at this workshop would be quality of service and active networking.
