Congestion control in multi-source connection-oriented networks with rate dependent sampling period Keywords: congestion control, connection-oriented communication networks, variable sampling period In this paper, flow control in a generic multi-source connection-oriented network is considered. A new, nonlinear controller based on the Smith principle is proposed. In the system under examination, the feedback information is received by each source once every M data unit sent by this source Round Trip Time (RTT) earlier. Since the rate is modified only when this information becomes available, the transfer speed changes at irregularly spaced time instants. A thorough mathematical description of the network model with variable sampling period is given. Subsequently, conditions for data loss elimination and full bottleneck link bandwidth utilization are formulated and strictly proved. Finally, the system robustness with respect to the imprecise RTT delay estimation is discussed and modified conditions, which allow favourable properties of the principal control scheme to be preserved, are presented. Since the rates generates by the controller are always nonnegative and bounded, the proposed strategy can be directly applied in real telecommunication systems.
