Today, in china the train dispatching problem and the problem of scattering the sudden passenger flow in minimal time widely appear in railway transportation in spring festival season. We try to apply the computer network to the railway transportation net and solve the problem of scattering the passenger flow in spring festival by using the solutions in computer network. It puts forth a solution to the granularity queue management and the queue dispatching that combines the QoSFR model with the temporary passengers' transportation program during the spring festival season. We should analyze the problems from the perspective of network technology and build up the model of solving spring festival transportation problem by using the solutions to network blocking problem in order to mitigate the serious spring festival transportation problem at present.
