Abstract:

With the queueing theory, the paper conducts a qualitative analysis to some of the guidelines in video service systems for batching, and analyses the   system service status in different scenarioes. With the average number of waiting customers and system throughput as the main targets to be studied, we give the relationships between system throughput, the average number of waiting customers, batching threshold value, system service degree and customer  patience degree. We also elaborate the effect on customer delay from the threshold value,service degree and customer patience degree. Simualtion results   show that this is also a way of saving the resources and enhancing the video service level.

Key words: video-on-demand, server throughput, queueing system, threshold value
