基于多优先级缓存队列的远程数据传输技术

为了实现多信道支持数据传输技术和混合通信模式的通信协议，从两优先级队列模型入手，分析、设计和实现一个具有多优先级处理能力的发送缓存队列数据传输机制，由面向上层的输入队列和面向不同信道的输出队列构成。为满足实际应用的要求，在队列模型的基础上增加数据包复用、发送状态反馈和换信道重发等机制。通过在一个远程监控系统中的实际应用和一系列实例测试，论证该队列机制具有一定的可行性和可靠性。

Remote Data Transmission Technology Based on Multi-priority Buffer Queue

In order to implement the communication protocol regarded to multi-channel supported data transmission technology and hybrid transmission mode, this paper achieves a data transmission mechanism based on multi-priority buffer queue by getting into the concept of two priorities queue mode. The mechanism is composed of data input queue facing to upper layer and data output queue facing to diverse communication channels. To satisfy the demand for the data transmission system, both retransmission mechanism of communication channel exchange and data packets reuse mechanism are added based on the queue model. Having gone through a practical application under remote monitor system as well as a series of example tests, it preliminarily identifies the feasibility and reliability of the designed queue model.
