In this paper, we propose an adaptive capacity
allocation scheme at the call level for a blocked call cleared loss
system. The scheme aims to maintain the connection blocking
probability around a specified target value by dynamically adjusting
the allocated capacity. Based on a fluid flow model of the loss
system, Lyapunov Stability theory is used to derive an adaptive
capacity adjustment scheme which guarantees overall system
stability around the target call blocking probability. Numerical
results are given which show that the Lyapunov control based
scheme is robust to load variations and performs better than
existing schemes in the literature.
