Paper Abstract

Recent and future communications networks have to provide QoS guarantees for a rapidly growing number of various telecommunication services, which can be ensured by application of an efficient MAC layer. Various communication technologies, such as cellular networks and PLC (PowerLine Communications) access networks, apply reservation MAC protocols, providing a good network utilization and realization of different QoS guarantees. In this investigation, we analyze possibilities for provision of QoS guarantees for various telecommunications services with a two-step reservation MAC protocol using per-packet reservation principle, which is proposed for application in broadband PLC access networks. Particularly, performance of the reservation procedure is analyzed to provide priority mechanisms which are necessary for realization of various telecommunications services ensuring the required QoS guarantees. Since the telephony, realized by the packet voice service, has the strongest QoS requirements among various telecommunications services, we analyze possibility for its realization within the two-step MAC protocol. It can be concluded that the packet voice can be efficiently implemented. However, with application of a combined reservation domains for various service classes, network performance could be further improved.
