Simulation and Verification of UDP Protocol with Fault-Tolerant Mechanism

摘要

In order to solve large amounts of data transfer problems of industrial control, the paper proposes a fault-tolerant mechanism for UDP (Class UDP). Simulation system was developed in NS II , it adopts two-level tree structure to simulate industrial control systems. The simulation system tests class UDP transmission performance. The measurements show that class UDP can provide better QoS guarantee for real-time industrial control and can well meet the requirements the real-time and accuracy of industrial control.
