Arbitrated Sharing of Traffic in Telecommunication Networks: Technoeconomical Considerations

Abstract

The technoeconomical aspects of implementing an arbitrated sharing of telecommunication traffic by CO (class 5) circuit-switches are studied. The traffic in question refers voice calls and dial-up modem data supported on network access lines terminated at the circuit-switches. Such time-division multiplexed (TDM) services still remain as the major revenue-earning products of public switched telephone network service-providers (and this i>status i>quo is expected to continue over several future years, despite of xDSL and/or IP-network penetrations). As such, this study was motivated to address an engineering effort to realize higher revenue-potentials through prudent sharing of the traffic between the circuit-switches. This arbitration in traffic-sharing is based on the diversity in the dynamics of traffic-demand posed by different subscribers (such as suburban-based residential customers and urban-based commercial end-users). The centum call seconds (CCS) metric is adopted to specify the traffic-load commensurate with the voice/dial-up modem sources. The heuristics of fair-proportioning considerations that let the switches serving a diverse population of subscribers so as to optimally vary (share) the traffic-load between switches i>via an arbitrated approach is discussed. Relevant metric for arbitration is defined in terms of a cross-entropy based complexity measure and an implementation scheme is proposed thereof. Computed results on traffic sharing algorithm are presented and discussed.
