Abstract: In this paper we develop several continuous time dynamic models for computer communication net works. This is based on the token bucket control mechanism: a traffic shaping mechanism used at the network access point. The first set of models is based on the assumption that there is no buffer used before the traffic is processed by the token bucket. The second second set of models allow buffering. Here there are two types: buffers followed by token buckets and buffers preceded by token buckets. The third set of models include priorities. Incoming traffic is split into two streams one with high priority and one lower priority. The mathematical model turns out to be a system of nonlinear differential equations with discontinuous right hand side. We model this as differential inclusions and prove the existence of solutions and viability of the admissible domain of operation. This is a class of nonstandard systems. We prove the existence and regularity properties of solutions for these systems and discuss control and optimization.
