DESCRIPTION:    Optimization of communication networks has recently witnes
 sed an impressive growth of research activities. In addition to viewing ne
 tworks as objects to be optimized\, some of these works also view networks
  as optimizers themselves. In addition to `Design by Optimization'\, some 
 recent results also demonstrate the principle of `Design for Optimizabilit
 y'. Indeed\, more than a tool to solve for optimal resource allocation\, o
 ptimization theory provides to networking applications all of the followin
 g: a modeling language for design\, a reverse-engineering methodology for 
 analysis\, a theoretical foundation for architectural decisions\, a quanti
 tative basis for fairness and robustness\, and even an indicator of flaws 
 in engineering assumptions. Many of these new uses of optimization actuall
 y do not involve solving any problem optimally.\n\n    Reflecting upon the
  history of optimization-based solutions to congestion\, collision\, and i
 nterference in the last 15 years\, this talk discusses the reach and limit
 ation of network optimization. Then\, drawing from recent results on open 
 problems in stochastic utility maximization and Internet routing\, this ta
 lk surveys the emerging trends that give many new meanings to the phrase `
 Optimization of Networks and by Networks'.\n\nA recent interview with spea
