一种基于以太网卡的实时网络的实现方法

IMPLEMENTATION OF A REAL-TIME NETWORK BASED ON ETHERNET CARD

实时网络要求网络上节点间数据传输时间是确定的，而常见以太网的数据传输时间并不确定，它是一种典型的非实时网络。本文给出了一种基于以太网卡的实时网络的体系结构，并详细描述了在传输层如何实现数据传输的时间确定性。

The data transmission time between nodes on a real-time network must be predictable. But the data transmission time of the Ethernet is generally not predictable, i.e. the Ethernet is a kind of typical non-real-time network. In this paper we present a real-time network architecture based on Ethernet card and describe how to implement it on transport layer in detail.
