顾名思义，本文档的范围是DPoE的MAC和上层协议 网络。DPoE网络中的MAC是EPON。本规范未规定任何额外要求 对EPON MAC的要求超出了EPON的[802.3]规范。第一套 要求用于支持基于DOCSIS的运行管理和维护 [MULPIv3.0]中规定的MAC和上层协议的资源调配（OAMP）。第二个 这套要求是对上述功能流量分类（如规定）的补充，以及 流量转发（根据本规范的规定和要求）。

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).
