“桥”应该是二层、也就是数据链路层（包括MAC）的设备，博通专利中的名称是CMC，意思是“Coaxial Media Converter”——物理层的转换。我的上一个邮件实际是对单纯物理层转换提出了疑问。但是我们希望MAC层不要分成两段——光和电各一段，也就是不希望当中有个桥接设备。在中国，EoC最初就是以“缆桥”命名的，其短板就是不能端到端。我们认为，解决的方案之一就是扩展EPON MPCP协议，在CMC（或者OCU、或者ECB，叫什么不重要）变换一下帧格式，也许还要增加一些预测帧，同时对数据存储转发，但是保持OLT对CNU的控制、管理、调度。

As I discussed in my earlier message, your statement below: ‘Bridge’ is actually the more generic term. In IEEE 802, a "bridge" is not a generic term. Rather, it is a specific type of device whose configuration in standardized in 802.1 Best regards, Geoff Thompson On 23//12 11:42 PM, Barr, David wrote:
