This paper shows how to provide an adaptive real-time group multicast(many-to-many) communication service. Adaptive means that the number of nodes that transmit to the multicast group is continuously changing. In order to meet deterministic quality of service (QoS) requirements of a real-time group multicast, some communication resources are reserved. In this work we show (i) how bandwidth is reserved for each multicast group, and (ii) how an active source can dynamically share the bandwidth allocated to this multicast group with other active group members. Quality of service support for a real-time multicast group i s based on time-driven pri- ority (9). In this scheme the time is divided into time frames of fixed duration and all the time frames are aligned by using a global time reference which can be obtained from GPS (global positioning system). Bandwidth is allocated to a multicast group as a whole, rather than individually to each user. The allocation is done by res erving time intervals within time frames in some periodic fashion. This sort of allocation raises two problems that are studied in this paper: (1) Scheduling: how time intervals are reserved to each multicast group, and (2) Adaptive sharing: how the active (transmitting) participants can dynamically sh are the time intervals that have been reserved for their multicast group. The proposed appro ach is based on embedding multiple virtual rings, one for each multicast group. By using the virtual rings it i s simple to route messages to all the participants, while minimizing the bound on the buffer sizes and queuing delays. The last part of the paper introduces a scalable growthof the multicast group by adding multiple subtrees to the virtual ring. |
