摘要
由于以太网的高性价比、高带宽和开放性,以太网成为最广泛的局域网技术,但是它缺乏对实时网络的支持。现代控制网络与数据网络的一体化,实时数据和非实时数据并存,如何分辨和优先处理实时数据、防止突发的非实时数据传输独占网络带宽,对此进行了探讨和实践。基于Linux的开放源代码,对Linux中的网络系统加以改造,使Linux支持实时通信。
Ethernet have been becoming a widespread technology in Locale Area Network(LAN), due to its characters of high performance, low price ,high bandwidth and opening. But it does not support real-time communication. In the union of mo-(dern) control network and data network, real-time data and non-real-time data coexist. The paper probes into how to identify and give priority to real-time data and how to prevent the burst non-real-time data to contend for bandwidth. Based on the open source code of linux, the modification of net subsystem in linux was made, and make linux support real-time communication.
