Management subsystem design supporting reliable data transmission for future networks

In order to ensure the user´s normal call which rely on the soft-switch platform in future network, we designed an experimental system to intercept DOS attack. In this paper, based on SNMP protocol, we designed the management subsystem of the experimental system to control the operation of every subsystems of the coordinate system. Firstly we designed the overall framework and the module function of every subsystem, secondly, on this basis, the implementation of the management subsystem will be given, which is mainly through the expanded MIB and the corresponding SNMP operations. The management subsystem designed in this paper ensure proper operation of the entire system in the actual development, especially, we made innovation of the SNMP protocol in data transfer between subsystems, which is of certain theoretical practice.
