SUMMARY:Exploring the dynamics of network optimisation - Nigel Walker\, Be
 n Strulo\, British Telecomm
DTSTART:20090114T160000Z

CONTACT:Neil Walton
DESCRIPTION:As proposed by Frank Kelly\, network control protocols can be 
 usefully\ninterpreted as dynamically solving a distributed optimisation pr
 oblem or\, more\ngenerally\, as seeking the saddle point of a Langrangian 
 function. We will\npresent some graphical notation and theoretical results
  that we use to explore\ndesign options for dynamics in these systems. The
 se techniques allow us to\nassociate a variety of dynamic systems with a g
 iven Lagrangian\, in each case\nwith an immediate convergence proof.\n\nIn
  the talk we will outline these ideas as they apply to some recent proposa
 ls\nin the area of multipath flow control.\n
