Abstract: Non-cumulative layered streaming in synchronous collaboration environments has received little attention due to overhead associated with uncoordinated receivers' subscriptions to different layers of the multicast stream. This paper presents a new layer coordination algorithm for such streams, termed Implicit Layer Coordination Algorithm (ILCA). ILCA computes, prior to multicasting, a representative layer combination for each attainable throughput that maximises the overlapping among the receivers. Consequently, ILCA can be deployed in the Internet for arbitrary non-cumulative layered multicasting. ILCA employs two search strategies (genetic and heuristic) to compute representative layer combinations. Complexity analysis shows the computational feasibility of ILCA. Simulation results demonstrate that ILCA can increase the overlapping among receivers' subscriptions and decrease the average number of joinings and leavings that receivers perform to change their rates. As a result, ILCA increases the average receiver throughput by 14-57%.
