Abstract: A terminal authentication method in a passive optical network (PON) which includes, receiving, by the optical line terminal (OLT), a registration request that carries an authentication parameter and is sent by the optical network terminal (ONT), where the authentication parameter is used to identify the ONT of a same type, and determining, by the OLT, that the authentication parameter sent by the ONT matches the authentication parameter preconfigured on the OLT, and authorizing that the ONT is an authorized terminal. Using the foregoing technical solutions, an OLT may be, during optical network unit (ONU) registration and authentication, plug-and-play, without needing to manually input authentication information, which improves automation and flexibility of authentication.

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.
