Near-Optimal Link Allocation of Blockable Narrow-Band and Queueable Wide-Band Call Traffic in ATM Networks
Ernst Nordström · 2001
This paper presents an adaptive scheme for a sub-function in ATM network routing, called link allocation, under blockable narrow-band and queueable wide-band call traffic assumptions. The scheme adapts the link allocation policy to the offered Poisson call traffic such that the longterm reward is maximized. It decomposes the link allocation task into a set of link admission control tasks, formulated as semi-Markov Decision Problems. The link admission control policies are adapted by the policy iteration algorithm. The long-term reward (throughput), fairness and average waiting time in the queue of the scheme are evaluated numerically.
