摘　　要：针对信道资源有限的高级数据链路控制(High Level Data Link Control,HDLC)通信,提出了一种零开销的带内管控技术。该技术采用输入输出异步缓存、高频管控帧插入、高可靠管控帧提取的方式,构建带内管控数据通道,实现了对HDLC帧数据的零开销管控。该技术可有效解决HDLC帧端到端满带宽通信情况下,零开销带内管控的设计难点。最后,给出了基于现场可编辑逻辑门阵列(Field Programmable Gate Array,FPGA)的实现方案和功能仿真验证结果。A zero-overhead in-band management and control technology for HDLC(High Level Data Link Control) frame communication with limited channel resources is proposed.In this technology,the methods of input and output asynchronous cache,high frequency management and control frame insertion,high reliability management and control frame extraction are used to construct in-band management and control data channel,which realizes zero-overhead management and control of HDLC frame data.This technology can effectively solve the design difficulties of zero-overhead in-band management and control under HDLC frame end-to-end full bandwidth communication.Finally,the implementation scheme and function simulation verification results based on FPGA(Field Programmable Gate Array) are given.
