Abstract: A bandwidth allocation method and a related device are disclosed. An exemplary method includes: when a total sum of a cumulative sum of fixed bandwidth configuration upper limits of traffic bearing entities and a cumulative sum of assured bandwidth configuration upper limits of the traffic bearing entities is greater than a maximum bandwidth value of a passive optical network (PON) port of a piece of central office equipment, determining, by the central office equipment based on a bandwidth configuration upper limit of each traffic bearing entity and a required bandwidth value of the traffic bearing entity, a bandwidth value actually allocated to the traffic bearing entity. In this way, a part of bandwidth is allocated to each traffic bearing entity. This avoids a case in which no bandwidth is allocated to some traffic bearing entities. Therefore, resource allocation is more appropriate.

Abstract: The present disclosure relates to information transmission methods, optical line terminations (OLTs), optical network units (ONUs), and communications systems. One example method on an OLT side includes allocating, by the OLT, an identifier to a first ONU through a first channel, performing, through the first channel, ranging on the first ONU to obtain ranging information about the first channel, and after determining, by the OLT and the ONU through negotiation, to use two channels to perform information transmission, performing, by the OLT, data transmission of a first service with the first ONU through a second channel.
