In this paper we design and demonstrate a signaling architecture for multicast and broadcast services over a laboratory emulated WiMAX network. WiMAX is a broadband wireless access technology which includes different QoS levels. Currently, a significant research effort focuses on data transmission optimization and mobility support for multicast and broadcast services. Our proposal is fully IP-based, and the relevant signaling architecture is modular in all its entities and extensible to other, non WiMAX, IP access networks. We specifically address the non trivial support of multicast services, which has been demonstrated through a prototype implementation of our proposal for an IPTV service. This prototype has been implemented by using open source technologies and its signaling is orchestrated by a JAIN SLEE server. The results obtained show that the implemented system is scalable, can achieve both high signaling throughput and low service latency, and has a signaling overhead lower than similar IMS-based solutions.

Abstract
In this paper we design and demonstrate a signaling architecture for multicast and broadcast services over a laboratory emulated WiMAX network. WiMAX is a broadband wireless access technology which includes different QoS levels. Currently, a significant research effort focuses on data transmission optimization and mobility support for multicast and broadcast services. Our proposal is fully IP-based, and the relevant signaling architecture is modular in all its entities and extensible to other, non WiMAX, IP access networks. We specifically address the non trivial support of multicast services, which has been demonstrated through a prototype implementation of our proposal for an IPTV service. This prototype has been implemented by using open source technologies and its signaling is orchestrated by a JAIN SLEE server. The results obtained show that the implemented system is scalable, can achieve both high signaling throughput and low service latency, and has a signaling overhead lower than similar IMS-based solutions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
