Multicast Admission Control for Multi-Domain Secure Ad Hoc Networks

We are proposing novel approaches for implementing a flexible, feasible and interoperable multicast admission control mechanism (McastAC) that is located at the red side of the typical Army black and red networks environment to provide end-to-end QoS assurance: • McastAC decisions are based on resource-friendly network performance estimations, which enable quick reaction to the status change of the network caused by radio dynamics and traffic congestion. • McastAC employs content filtering, where the admission/rejection decisions are based on utility and proximity. As such, together with DiffServ, McastAC ensures the high-priority mission critical applications are protected. The role of McastAC will be presented in the context of real-video applications with strict QoS requirements, in terms of packet delay and losses. In this architecture, we are proposing an innovative Multistream Multicast which ensures fairness between receivers with different capacities. A limited number of streams of the original content are sent over different multicast groups. The video receivers can switch between active multicast sessions by requesting admission to a different multicast group, in a manner that minimizes the disruption of the received video quality. Infocom Technology will leverage their extensive experience in video multi-streaming and multicasting to support this effort.
