Abstract

One of the methods for taking advantage of multicast services is the use of batching. With this method, several request of the same video are grouped and transmitted together, using only the bandwidth required for one transmission. This method is commonly used in transmission of streamed data. In this paper we analyze the system performance with explicit constant batching, and demonstrate that a system without explicit batching performs better in terms of delays. We also propose a dynamic batching policy which improves the system performance both in mean and in maximum serving times.
