We present a State Estimation based Internet traffic flow control system where the objective is to maximize the aggregate bandwidth utility of network sources over their transmission rates. The network links and sources are viewed as processors of distributed computation and the control mechanism is based on estimation and optimization framework to solve the dual problem. The novelty of our approach...
Aggregation of flows into classes is used to avoid the scalability problems of IntServ model and this requires per-class scheduling decisions. There are number of issues associated with such approach e.g. what will be per-flow guarantee, which flows are to be aggregated together, how to determine service order among multiple classes and within a class etc. DiffServ model is a framework wherein class...

Quality of service (QoS) in the Internet depends on queuing and sophisticated scheduling in routers. In this paper, we address the issue of managing traffic flows with different priorities. In our reference model, incoming packets are first classified based on their priority, placed into different queues with different capacities, and then multiplexed onto one router link. The fuzzy nature of the...
