Design and implementation of an advanced service architecture for MBS over WiMAX

The WiMAX technology has all the necessary features to effectively provide multicast/broadcast services: (i) it is a broadband access technology, (ii) being wireless, it has intrinsic broadcast capabilities, and (iii) it can provide differentiated quality of service levels. Leveraging on these features, we propose a signaling architecture for multicast/broadcast services exploiting the MBS specification in the Mobile WiMAX standard. The signalling is orchestrated by a JAIN SLEE server. We illustrate this architecture, which is highly modular and based on standard communication protocols (i.e. HTTP, SIP, IGMP), and focus on the design and implementation of the signaling part for a multicast video streaming service.
