图像具有直观、方便和信息量丰富等特点,其网络传输已经渗透到了生产生活中的各个领域。为了满足日益增加的网络传输信息量和速度要求,网络传输中采用实时操作系统和实时网络协议的技术受到越来越多的关注和应用研究,本文设计并实现了图像在实时操作系统RTAI和实时以太网RTnet环境中的传输。结果表明,通过实时网络协议RTnet传输同等信息的速度明显优于标准Linux网络协议栈。
The images are characterized by intuition, convenience and rich information, and their network transmission has permeated every area of production and life. In order to meet the increasing demand of information and speed of network transmission, the technology of real-time operating system and real-time network protocol in network transmission is receiving more and more attention and application research. This paper designs and realizes the real-time operating system RTAI and real- Transmission in Ethernet RTnet environment. The results show that the same information transmitted through real-time network protocol RTnet is significantly faster than the standard Linux network protocol stack.
