1. An optical line terminal (OLT), configured to communicate in an optical network with optical network units (ONU)s, and to receive packets from the ONUs, the OLT comprising at least one processor and at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the OLT to perform:
determining a fragmentation allocation for respective ONUs based on information on OLT resources available for processing the packets from the ONUs, the fragmentation allocation indicating at least one enabling or disabling fragmentation for data traffic for the respective ONUs;
deriving an upstream bandwidth allocation map for the respective ONUs based on the determined fragmentation allocation; and
notifying the respective ONUs of the determined fragmentation allocation.
