Client Service Ability Calculation Based on FCM

The video grid with hybrid architecture provides video services by using client resources so as to the streaming path of video data was shortened and the service ability of system was enhanced. However, it is too hard to get the service ability of the system because the service ability provided by clients is not calculated easily while these clients have great heterogeneity and dynamism. Aiming at the problem, a method for calculating client service ability based on FCM (Fuzzy Cognitive Map) was proposed through studying the composition of the video grid with hybrid architecture and the interrelations among factors which affecting client service ability, and then, the mathematical model was built for calculating the client service ability. The test results produced by Any Logic, a simulation software, showed that the mathematical model is reliable and correct, and it can be used to calculate the client service ability in the video grid with hybrid architecture.
