Algorithm for Non Conflict Schedule in Sub Matrices Optimal in Terms of Performance and Memory

Open access

Abstract

The paper deals with the problem of traffic scheduling in a crossbar switch node used in communication networks. In particular, we study the non-conflict scheduling in sub matrices of the connection matrix of an Algorithm with diagonal activations of joint sub matrices (ADAJS) and propose a scheduling algorithm which is optimal in terms of performance and the necessary memory. For comparison, we have examined six algorithms with their software models.
