Provided are a method and system for improving bandwidth allocation efficiency, relating to optical communication field. In a PON system, an ONU detects each TCONT of the ONU in real time, and sends to an OLT a private message used for reporting buffer overflow when detecting that buffer overflow occurs on a TCONT; the OLT sends, according to the received private message used for reporting the buffer overflow, to the ONU a private message used for instructing the ONU to activate an overflow allocation mechanism; after receiving the private message used for instructing the ONU to activate the overflow allocation mechanism, the ONU activates the overflow allocation mechanism, calculates an actual traffic of a buffer of the TCONT, and sends the actual traffic of the buffer of the TCONT to the OLT; and the OLT dynamically allocates bandwidth to the TCONT according to the actual traffic of the buffer of the TCONT. |
