NettetMPCP（Multi-Point Control Protocol，多点控制协议）是EPON MAC控制子层的协议。. MPCP定义了OLT和ONU之间的控制机制，来协调数据的有效发送和接收。. EPON系 … NettetTo enable timeslot assignment, the IEEE 802.3ah task force is developing a Multi-point Control Protocol (MPCP). MPCP uses two MAC control messages: GATE and Passive Splitter 3 REPORT*. The GATE message is sent from the OLT to an ONU and is used to assign a timeslot to the ONU.
