| Abstract: | In order to reduce the network deployment costs for service providers at the process of video demanding service,a flexible service-oriented method was proposed.According to the sampling theory,firstly a prediction model of the reaching rate of video demanding at different times was established.Based on this,a systemic flexible service-oriented method through employing fluid model,stability theory of differential equations and signaling game theory was provided.This method can effectively reduce deployment cost and increase system scalability and the quality of video distribution.Finally simulation experiment verifies the feasibility of this method. |
