Performance Analysis of Multi-Priority Buffer Queue and Its Application of Data Transmission System in Remote Monitoring System

To achieve flexible support for multi-channels supplied by remote monitor system and to implement hybrid transmission mode, this paper designs and introduces a mechanism of data transmitting buffer queue, which is with multiple priorities processing. The mechanism is composed of data input queue facing to upper layer and data output queue facing to diverse communication channels and it contains retransmission mechanism of communication channel exchange and data packets reuse mechanism in order to fulfill the efficiency and reliability of remote monitor. By analyzing the performances of queue model and time-delay with the aid of parameter hypothesis based on traditional queue and example tests of hybrid communication model, the paper demonstrates the feasibility and reliability of the designed queue model.
