Abstract:
Embodiments of the present invention disclose an EPON communication method, an ONU, and an OLT. The method includes: generating, by an ONU, a first control frame, where the first control frame includes a first data field, and the first data field includes a bandwidth requirement of the at least one LLID; and sending, by the ONU, the first control frame to an OLT. In addition, the OLT generates a second control frame, where the second control frame includes a second data field, and the second data field includes grant information of the at least one LLID; and the OLT sends the second control frame to the ONU. In the embodiments of the present invention, the first control frame may carry bandwidth requirements of a plurality of LLIDs, so that one first control frame can be used to report bandwidth requirements of a plurality of LLIDs.
