ABSTRACT:
The present invention provides a method and apparatus for transmitting control signal of Resilient Packet Ring (RPR) Medium Access Control (MAC), including: encapsulating a control signal of RPR MAC interface to be transmitted into an RPR data frame of predefined format, and directly sending it to a receiving unit through a standard interface. In this invention, an RPR data frame of predefined format is utilized to transmit signals between an RPR MAC and a receiving unit, e.g., an RPR client, via standard interfaces, which may avoid the increase of unstable factors affecting signal transmission and hardware cost caused by the appending of hardware devices in the standard interfaces. Thus, the reliability of signal transmission is enhanced, and the hardware cost of communication system is reduced.
