Abstract
A bandwidth assignment method and apparatus, and an optical network system are disclosed. The method includes: setting a maximum bandwidth grant size and a maximum burst bandwidth grant size for an optical network unit; receiving a bandwidth assignment request of the optical network unit; and when an optical line terminal determines, according to the bandwidth assignment request, that a bandwidth grant size requested to be assigned in the bandwidth request is greater than the set maximum bandwidth grant size and less than or equal to the set maximum burst bandwidth grant size, determining, by the optical line terminal, in response to the request, to assign the requested bandwidth grant size to the optical network unit. Therefore, timely and accurate transmission of massive uplink burst data traffic is ensured, a transmission delay is reduced, service performance is improved, and system bandwidth utilization is greatly increased.
