摘　　要：针对现有多协议高速接口在实际应用过程中出现的无法即插即用的问题,文中提出一种应用于软件定义互连系统的非主动配置接口协议的物理层协议自协商机制。首先,通信双方对接收到的多协议特征序列进行识别,剔除双方无法识别的协议,保证双方在协议数量相同的情况下工作;然后,双方围绕接收协议与发送协议进行协议一致性的协商,该机制通过对比判决的方法缩短协商时间,进而保证双方的正常互连互通。仿真实验结果表明,物理层自协商机制能够有效应对非主动配置接口协议下,通信双方经过物理层协商仍建立稳定数据通信的过程。In allusion to the problem that the existing multi⁃protocol high⁃speed interface cannot be plug⁃and⁃play in the practical application,a physical layer protocol auto⁃negotiation mechanism for non⁃active configuration interface protocol applied to software⁃defined interconnection system is proposed.The multi⁃protocol feature sequences received by both parties of the communication are identified to eliminate the protocols that both parties cannot identify,so as to ensure that they can work in the case of the same number of protocols.The two parties carry out negotiation of the protocol consistency around the receiving protocol and the sending protocol.This mechanism can shorten the negotiation time by the contrast judgment method,thereby ensuring the normal interconnection between the two parties.The simulation experiment results show that,under the non⁃active configuration interface protocol,the physical layer auto⁃negotiation mechanism can effectively deal with the process of stable data communication established by means of the physical layer negotiation coming from both parties.
