Communication Networks:Modeling Modern Multimedia Traffic
Network routing, a critical element of network management, consists of the decision rules to connect the pairs of origins and destinations in order to communicate at a given rate on a given topology with fixed link capacities. In the hierarchy of decision problems that dominate network management, routing stands between network design (where topology, facility location and capacity assignment are considered under long-term strategic objectives) and flow control (where traffic is dynamically organized under short-term operational objectives at each switch and router along the routes specified by the routing module). These decision levels are strongly interconnected, giving rise to integrated optimization models at each interface, such as capacity and flow assignment or routing under quality of service constraints.
