摘　　要：针对目前工业生产和科研领域对大量实时数据传输的迫切需要,在分析现存各种网络协议的优点和不足的基础上,融合UDP协议和令牌总线 802. 4标准的优点,提出了基于UDP协议和虚拟令牌的实时网络协议。对该协议如何实现“实时性”和“可靠性”的机理进行了详细的阐述,给出了该协议的帧格式及虚拟令牌的格式。最后用一个使用该协议实现的点到点传输的实例,对该协议的性能进行了初步的论证。Aiming at the urge demand of a large amount of real-time data transmit in industry and academy fields, the authors analyze the advantages and disadvantages of many kinds of present protocols, take advantage of UDP protocol and standard 802.4 of Token Bus. The real-time network protocol is presented based on UDP protocol and virtual token. And this paper illuminates the principle of real-time quality and reliability about the protocol, giving the frame format of the protocol and the format of Virtual Token. It demonstrates the capability of the protocol with a point-to-point transmit example that constructed according to this protocol.
