Abstract:

The paper uses the method of queueing theory to perform a qualitative analysis of some target data under the unicast situation of video service systems, analyses the system service states, gives the relationship between the average of customer request, system service load and the customer patience degree, and describes the effect of service load and customer patience degree on the system throughput. Simulation rcsuhs show that this is also an effective qpproach to saving resources and improving the video service level.

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