An improved time-slot assignment algorithm for TDM hierarchical switching systems
S. Chalasani, A. Varma · IEEE Transactions on Communications · 1993
It is shown that any hierarchical switching system can be modeled by a special class of flow networks called unit networks. Using the results available for finding maximum flow through a unit network, a time-slot assignment (TSA) algorithm that runs in O(min(L,M/sup 2/)*min(N, square root M)*M/sup 2/) time is presented. This is an O(max(M/N, square root M)) improvement over the TSA algorithm proposed by M.A. Bonucelli (1989).>
