Appropriate multi-access( MAC) protocol is the key to improving the network performance. The application of contention-free high frequency ( HF) token ring protocol in the HF data communication net-work can effectively avoid data collision, offer better network throughput and access time-delaying, and thus is beneficial for HF to bringing its superiority of strong resistance and long communication distance in-to full play. This paper summarizes the basic profile of HF token ring protocol. From the aspects of relay mechanism, pathological topologies, merging process of token ring and node state transition, the latest re-search on operating mechanism of the protocol is highlighted and research direction for the future work also pointed out.
