Abstract

In this paper, the lower bounds for the actual stability margins are derived for a rate-based flow control problem in multiple bottleneck communication networks. Considered stability margins are for the uncertainties in the multiple time-delays and for the rate of change of the time-delays. To observe the change in the actual stability margins with respect to the uncertainties in the time-delays and the rate of change of the time-delays, the lower bounds on the actual stability margins for differentcases are depicted.
