摘　　要：在以太网发展到快速以太网时,为了实现不同速率的以太网设备混合通信,在介绍以太网自协商的概念以及基本原理的基础上,较详细地说明了千兆以太网自协商的三种page帧结构。重点阐述了千兆以太网端口的自协商基本过程,并以1000BASE-T为例分别介绍了千兆以太网端口的自协商接收与发送流程。To realize the hybrid communication of different rates Ethemet devices since the Ethemet developed to the Fast Ethernet, on the basis of describing the fundamental principle of Ethernet Auto-negotiation, illustrates the three page frames structure of GB Ethernet Auto-negotiation. The process of GB Ethemet Auto-negotiation is emphasized, and introduces the Auto-negotiation receiving and transmitting process of GB Ethemet ports individually take the 1000BASE-T for example
