This article proposed the congestion control mechanism,which reduced network congestion on account of the custody transfer protocol adopted was likely to result in the depletion of node cache resources,through the method of reserving the cache resources for the followed and high priority assignments to improve their service quality. The simulation results show that in one hand,the method of congestion control which introduced above is useful for relieving the network congestion and also effective in improving the transmission performance for the high-priority assignments on the other hand. However,it sacrifices the quality of low-priority service on the extent.
