QoS-oriented interdomain live streaming overlay multicast algorithm

This paper develops a live streaming service grid(LSSG) as an extensible overlay multicast middleware architecture for supporting live media applications in tele-cooperate environment over multiple domain.The LSSG service is provided by the service brokers nodes(SvB) which are strategically deployed by network service providers.This paper mainly presents a QoS-oriented inter-domain overlay multicast algorithm(QIOM),which is used to organize the SvB to build a QoS-aware multicast service tree.It is an overlay based the multicast connection solution for live media relay in different domains,which makes the inter-domains resource management turning to the dynamic cooperating service management.The simulation results show that the QIOM algorithms can effectively find and provide QoS-assured overlay services and balance the overlay traffic burden among the SvB.
