Implementation of the No Packet Loss Network Communication in VxWorks

  •  Linfang Zhang    


By VxWorks, the real-time control system of certain equipment adopts the UDP/IP network communication, which requires that the control process has strong real-time character and complex task scheduling. In the work condition with frequently interactive network tasks, the control system is easy to lose packets, and to solve this problem, this article adopts the double-loop buffer structure processing mechanism to realize the no packet loss network communication method, which could largely enhance the reliability of the network communication and improve the stability of the control system. Based on the excellent multi-task scheduling ability of VxWorks, this method could essentially enhance the efficiency and reliability of software. By testing, this method is efficient and feasible.
