33. Research on the QoS Guaranteed Mechanism for the Private IP Network

In the private network, end-to-end QoS plays very important role for the real-time trial data transmission. Considering the features of the network and the respective QoS requirements, the general principle of QoS deployment is studied in this paper. Following the principles, the model of end-to-end QoS used in the private network is established firstly. Then it is analyzed and demonstrated that how to deploy the QoS strategy in the kernel layer, cluster layer, and access layer of the private network, respectively. Furthermore, the solution is also designed to accomplish the QoS for the burst data and in other special conditions. Finally, the all-around scheme of end-to-end QoS is proposed for the private network, which provided the theoretical basis and guidance for bringing the QoS into effect. The proposed mechanism could be a valuable reference of significant practical meaning for other private IP networks.
