Abstract: QoS is the key to implement integrated service on computer networks. This paper designed a new solution support the differentiated services which based on analyzing the requirement of IP control gateway,and implemented the QoS for the IPCG. This thesis also mentioned that the user of the IPCG would be ordered by different priorities. Finally,the performance testing will show that implementation the QoS module for the IPCG will satisfy the users’ separate requirement without adding additional resources.
