METHOD AND DEVICE FOR CONTROLLING COMMUNICATION BUS

摘要

Provided are a method and a device for controlling a communication bus. The method includes: delay time is set differently for different line cards; the line card performs delaying according to the delay time set for the line card when detecting that the communication bus is idle; the line card that has finished time delay preempts the idle communication bus to send data to the communication bus. The invention solves the problem of great collision occurrence probability caused by traditional technological methods, reduces the data packet loss ratio caused by collision, improves the working stability of the bus and enables corresponding equipment to work with greater reliability and stability.
