Study of Measurement Methodology for Satellite Network Traffic
卫星网络流量测量方法的研究

Taking into account the features of satellite networking, solving the measurement for traffic in satellite networks by adopting passive measurement method based on SNMP is studied in this paper. The principle of measurement for network traffic using SNMP is studied firstly. Based on this, a selecting algorithm of nodes monitored is introduced so as to decrease the number of devices monitored and enhance the network performance of measurement for traffic. Finally, the flow chart of application explored in practice and the related experimental results are given. Further calculating or statistical disposing using the results can be processed. Then the distribution and utilization of resources in satellite network can be confirmed and the network can be adjusted to the optimal performance. The whole procedure of measurement for traffic is implemented and real-time exact data and available network management evidence are provided for the implementation of traffic engineering in satellite network.
