A study on two-level network monitoring system for space ezploration

摘要：

One of the promising and relatively new directions for space exploration is research of two-level network, i.e., space network and ground network. The paper proposes a two-level network monitoring systeM model and implements the model based on SNMP (Simple Network Management Protocol). The management mechanism of this system is that the priority of ground part is higher than that of the space part so that the ground part could manage the space network. Encrypted configuration files are used to realize the two-level network configuration management. In order to decrease the expense resulted from the loss of the data caused by the rupture of the link, two policies are needed to compensate the loss data. One is to transmit based on request; the other one is detected periodically. The model is supportive to space exploration.
