Abstract
The biggest obstacles in the design and implementation of Internet-based control are the Internet transmission delay and data loss. There are two ways to deal with this issue: one is from the network infrastructure perspective and the other is from the control system structure design and compensation algorithms perspective. This chapter addresses the time delay and data loss issue only from the network infrastructure viewpoint. Firstly, six requirements for an ideal network infrastructure are proposed, followed by a description of the features of Internet communication. In order to meet the requirements of real-time data transmission, a combined network infrastructure is investigated, which integrate The Transmission Control Protocol, User Datagram Protocol, Real-time Control Protocol, and the Network Time Protocol. The advantages of each transmission protocol have been used in the integrated infrastructure with the elimination of their weak features.
