摘要： A method of operation of a network transport system includes: determining a congestion mode based on a total bandwidth request meeting or exceeding a bandwidth threshold, where the congestion mode indicates a level of network traffic and the total bandwidth request is a sum of all bandwidth requests for accessing the network; calculating a fixed information rate schedule grant based on a fixed information rate list to create a bandwidth grant for a fixed information rate request; calculating a low latency schedule grant based on a low latency list to create the bandwidth grant for a low latency request; calculating a main schedule grant for allocating an available bandwidth based on the congestion mode, where the main schedule grant is calculated using a weighted maximum-minimum fairness method when the congestion mode indicates congestion; and generating a grant packet for defining a transmission schedule of a first network unit.

摘要： There are disclosed systems and methods for detecting and controlling congestion in an Optical Line Terminal (OLT). The OLT has a plurality of ports. Each port of the plurality of ports communicates with at least one Optical Network Unit (ONU), and each port of the plurality of ports has a respective enforced maximum upstream bandwidth. For example, the maximum upstream bandwidth may be enforced by a Dynamic Bandwidth Allocation (DBA) algorithm. The OLT further includes an uplink port through which data received from each of the plurality of ports are transmitted. In one embodiment, if there is congestion of the data at the uplink port, then the enforced maximum upstream bandwidth for at least one port of the plurality of ports is modified.
