摘要:: 协议设计质量的好坏直接关系到所开发出来的协议功能、性能等是否满足用户需求,以及协议后期维护成本。通信环境是协议设计需要优先考虑的问题。只有充分了解和定义了协议运行的通信环境,才能准确地设计出协议的其它元素,保证协议在功能上和性能上满足用户的需求。基于此,重点讨论了高级数据链路控制协议（HDLC）和帧中继（FR）两种协议的运行环境和特点,通过与其他协议的对比,总结了通信环境对协议设计可能产生的影响。只有从通信环境中的用户需求、（n-1）层通道性质等各方面去把握协议将来的运行环境,才能设计出实际可行的协议

Abstract:: The quality of protocol design will be able to influence the performance of protocol, the cost of protocol maintenance, and whether the protocol function meet the needs of user. At the same time,communication condition should be the first issue which to be considered in the process of protocol design. Other elements can be designed exactly unless comprehend and define the communication conditions of the protocol adequately, and then the protocol meets the requirements of the user on function and performance. First introduce something about the HDLC and FR, and then analyze the communication condition of these two protocols. At last, it summarizes the influence of communication condition to protocol design
