Abstract：To improve the quality of service(QoS)of the multimedia integrated services digital network(ISDN)of the coalmine enterprises,the hierarchical structure of QoS network and the model of the gateway node were proposed based on the characters of the coalmine network.U-sing approach of the DiffServ,the services of the coalmine network were classified and marked by per hop behavior(PHB),and the discard and schedule algorithm of queue packet were pro-posed to differentiate the services.The results show that the scheduled bandwidth can be ob-tained by the services closely related to the coalmine safety production,even facing multi-kind services and huge data amount.The average packet delay was steadily kept at 40.4-41.2 ms,the delay jitter was less than 0.46 ms,and the packet loss rate was zero.The remaining band-width can be obtained by scavenger services.The average packet delay differed from 42 ms to 56 ms,the delay jitter varied at 1.7-3.6 ms,and the packet loss rate reached 47.6%.
