Applications of Server Performance Control with Simple Network Management Protocol

Automated performance control is seen to be necessary when application server is overloaded due to over utilization of critical resources. Using Simple Network Management Protocol (SNMP) to provide controlled network device’s feedback, centralized server control model is applied in this paper. The method to choose the minimum sampling period in a network control system is then presented and thresholds are yielded based on Round Trip Time (RTT) testing results. An admission control system in a genetic algorithm server is further illustrated step-by-step, where two classical controllers, i.e., proportional controller and intelligent controller are introduced. Analysis to the stability of network control is subsequently discussed in detail. We finally use a real computer control model to test the control effects. The experiment results show the efficiency of the control approach to automatically controlled network systems.
