Communications in addition to computing Compute Communicate Communicate Store Communicate Compute Physical world & Environment Act Communicate Communicate Store Communicate Computation Devices Dynamical Systems Devices Communication Communication

From Software to/from human Human in the loop To Software to Software Full automation Integrated control, comms, computing Closer to physical substrate Computation Devices Dynamical Systems Devices Communication Communication Control New capabilities & robustness New fragilities & vulnerabilities Two great abstractions of the 20th Century Separate systems from physical substrate Separate systems engineering into control, communications, in addition to computing Theory Applications Facilitated massive, wildly successful, in addition to explosive growth in both technology in addition to mathematical theory but creating a new Tower of Babel where even the experts do not read papers or underst in addition to systems outside their subspecialty. Biology in addition to advanced technology Biology Integrates control, communications, computing Into distributed control systems Built at the molecular level Advanced (e.g. CBA) technologies will do the same We need new theory in addition to math, plus unprecedented connection between systems in addition to devices Two challenges as long as greater integration: Unified theory of systems Multiscale: from devices to systems

Recent convergences Molecular biology in addition to advanced technologies have only recently provided us with detailed in addition to well-understood examples of networks of previously bewildering levels of complexity. These examples confirm theoretical insights obtained from an exciting new mathematical framework, that as long as the first time offers a research path to a unified theory. With the hindsight that these examples in addition to theory give us, we can now underst in addition to the failure of recent attempts at a “new science” of “emergent” complexity. And finally outline a research program with both rigor in addition to relevance to complex networks in technology in addition to biology.

HTTP TCP IP Routing Provisioning Horizontal decomposition Vertical decomposition These decompositions are essential features as long as robust networks, but “break” st in addition to ard mathematical theories from engineering in addition to science. Coherent, complete theory is missing but possible. First cut nearly done. New insight in addition to promising new protocols with some provable robustness characteristics. Beginnings of deep theory of complex networks.

Heavy tails in addition to divergent length scales are everywhere in networks. There is a large literature since 1994: Lel in addition to , Taqqu, Willinger, Wilson Paxson, Floyd Crovella, Bestavros Harchol-Balter, Heavy tails in networks Typical web traffic log(file size) > 1.0 log(freq > size) p s- Web servers Heavy tailed web traffic Is streamed out on the net. Piece of a consistent, rigorous theory with supporting measurements
