顾名思义，本文档的范围是DPoE网络的MAC和上层协议。DPoE网络中的MAC是EPON。除EPON的[802.3]规范外，本规范对EPON MAC没有任何其他要求。第一组要求是支持[MULPIv3.0]中规定的MAC和上层协议的基于DOCSIS的操作管理维护和供应（OAMP）。第二组要求是对上述功能流量分类（如规定）和流量转发（如规定并根据本规范中规定的要求）的补充。

As the name suggests, the scope for this document is the MAC and upper layer protocols for DPoE Networks. The MAC in DPoE Networks is EPON. This specification does not place any additional requirements on the EPON MAC beyond the [802.3] specifications for EPON. The first set of requirements is for the support of DOCSIS-based Operations Administration Maintenance and Provisioning (OAMP) for the MAC and upper layer protocols as specified in [MULPIv3.0]. The second set of requirements is in addition to the above functionality traffic classification (as provisioned) and traffic forwarding (as both provisioned and according to the requirements set forth in this specification).
