An example of a simple cache system for a video streaming implementation within a network simulation

Abstract—The modern expansion of public streaming has played a considerable part in the growth of distributed multime-dia, with special reference to video. However, since the Internet is an inter-connected web of different network speeds, streaming video is still a difficult service to implement to all locations. This paper illustrates two simple simulated network streaming environments. The first models a broadcast network and the second model represents a multicast network. A simple cache system is then implemented into these models to investigate whether a significant difference exists between the cache size and the different network bandwidths of these two optimization systems. This caching system will then be used to compare the impact of videos (characterised by different resolutions and degrees of picture motion) on the cache performance
