Abstract: In one embodiment, an optical line terminal, OLT, is configured to communicate in a passive optical network with optical network units, ONUs, that respectively comprise one or more transmission queues; wherein the OLT includes a dynamic bandwidth allocation, DBA, engine configured to allocate recurrent transmission opportunities to the respective transmission queues for transmitting packets from the respective transmission queues to the OLT; wherein at least one of the ONUs includes a L4S transmission queue for transmitting L4S packets with at most a service latency and at least a service bandwidth; and wherein the DBA engine is further configured to perform, identifying a L4S transmission queue based on a L4S traffic descriptor parameter provisioned within the DBA engine.
