Traffic analysis for a custom video architecture

A custom news service is analyzed. A service provider prepares and distributes daily news programs customized to subscriber interest. The customers may ask for their program any time in the evening, but may have to wait for a few minutes until their program starts. This service is modeled, and a network architecture that can support it is proposed. Popular material is stored closer to the customers, which decreases the load on the network. The delay that customer requests experience is addressed. Three approximate techniques capture the behavior of the system and are used for designing the network. It is shown that the service rate of the system should be approximately equal to the arrival rate so that the performance of the system is acceptable and the service is as economical as possible
