Research On QOS Management Of Satellite Broabdand Integrated Seryiceplatform

Satellite communication, as an important means of communication, has developed rapidly by digital technology. According to user's actual situation for Qos in the China Unicom VSAT satellite broadband platform, the requirements of QoS function is analyzed in this thesis. Based on the latest QoS management technology research, we find out a suitable QOS management mode in the VSAT satellite broadband platform for China Unicom. In the simulation and practical environment, the equipments of candidate factories are tested. Then we compare the advantages and disadvantages of the two typical manufacturers'equipments through the analysis of the test data. On the basis of the investigation and analysis for existing resources, this thesis expounds how to make full use of the new QoS equipment in VSAT satellite broadband service platform for the further development of China Unicom, and explains how to ensure the sustainable development of network.Through the above research, we attempt to get the following results:QoS requirements analysis and management function in present network, and the performance of QoS equipment, and the objective analysis of advantages and disadvantages for the different manufacturers'equipments. Then we make a plan for the Qos resource allocation and the QoS management framework by user requirements in the existing network. In the result, the development of VSAT satellite broadband platform in China Unicom is promoted healthily.
