DESCRIPTION:In the Internet today\, traffic management spans congestion co
 ntrol (at end hosts)\, routing protocols (on\nrouters)\, and traffic engin
 eering (by network operators). Historically\, this division of functionali
 ty evolved\norganically. We perform a top-down redesign of traffic managem
 ent using recent innovations in optimisation\ntheory. First\, we propose a
 n objective function that captures the goals of end users and network oper
 ators.\nUsing all known optimisation decomposition techniques\, we generat
 e four distributed algorithms that divide\ntraffic over multiple paths bas
 ed on feedback from the network links. Combining the best features of the\
 nalgorithms\, we construct TRUMP: a traffic management protocol that is di
 stributed\, adaptive\, robust\, flexible\nand easy to manage. Further\, TR
 UMP can operate based on implicit feedback about packet loss and delay. We
  show\nthat using optimisation decompositions as a foundation\, simulation
 s as a building block\, and human intuition as\na guide can be a principle
 d approach to protocol design.\n
