摘要
在高速数据传输网络中,用户数据报协议(UDP)有着其他数据传输协议无法比拟的优势,但同时也存在着传输可靠性差的问题。文章作者在详细分析UDP特点的基础上,对其关键技术进行了改进,设计了一种可靠的传输机制。文章最后给出了在VxWorks操作系统下实现UDP可靠传输的方法和流程。
In high-rate data transfer networks,User Datagram Protocol（UDP） has incomparable advantages over any other data transfer protocols,but it also has the problem of poor reliability in the transfer.On the basis of analyzing in detail the characteristics of UDP,this paper improves its key technologies and designs a reliable transfer mechanism.Finally,it offers a specific method and procedure for the realization of the reliable UDP transmission by VxWorks.
