Abstract

The present invention provides a bandwidth scheduling method, an ONU (Optical Network Unit) registration method and device, and an OLT (Optical Line Terminal). The ONU registration method comprises: an OLT determines a first system upstream bandwidth of a first PON (Passive Optical Network) system according to the number of ONU to be registered which are not yet scheduled to the first PON system of the system upstream bandwidth; the OLT opens a quiet window for the ONU to be registered in the first system upstream bandwidth; and the OLT completes the registration of the ONU to be registered in the quiet window. According to the invention, the problem is solved that the different system smooth upgrade of the ONU cannot be realized, the different system smooth upgrade of the ONU is realized, and the efficiency of the ONU upgrade is improved.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a bandwidth scheduling method, an ONU registration method, device and OLT. Background technique [0002] With the rapid development of broadband services, users' demand for access network bandwidth has increased significantly. Passive Optical Network (PON) is currently an important technical means for user access. The PON system is usually composed of an optical distribution network (Optical Distribution Network, ODN) composed of an optical line terminal (Optical Line Terminal, referred to as OLT) and an optical network unit (Optical Network Unit, referred to as ONU, or an optical network terminal ONT). ODN is usually a point-to-multipoint structure, that is, an OLT connects multiple ONUs. Generally, the OLT is in the downstream direction to the ONU, and the ONU is in the upstream direction to the OLT. [0003] The OLT and ONU communicate through a wavelength pair. The OLT opens ...
