ABSTRACT
In a streaming video multicast environment a large number of users often request various similar processing on the same stream. Therefore service sharing is feasible, with a large potential of savings in processing cost.The Service invocation order may play a significant role on service sharing in a streaming video multicast application. The problem is how to determine Service Invocation Order for multiple service composition requests with the aim of maximizing service sharing. This paper proposes BFS algorithm to maximize the service sharing in a streaming video multicast environment in order to reduce the processing cost and to increase the scalability. The service invocation orders for multiple service composition requests will be determined with the aim of maximizing the service sharing. The BFS algorithm merges the services level by level without changing the service invocation order.
