Abstract—Concerning the low scheduling ratio caused by complicated QoS process and precise match in learning resource scheduling of campus grid, the authors classified and defined QoS parameters. Finally simulations were performed to compare the performance of the maximum matching scheduling algorithm with that of the multiple QoS-based resource scheduling algorithm. The paper improve a mode of learning resource dispatching which fit to campus grid,also improve the algorithm of multi-level resource dispatching.

Keywords:Campus grid,learning resource sharing, learning resource dispatching.
