SYSTEMS AND METHODS FOR DETERMINING ROUTING DATA BASED ON EXPLICIT CONGESTION NOTIFICATIONS AND ACTIVE QUEUE MANAGEMENT ENABLED NETWORK DEVICES
A device may receive explicit congestion notification data associated with user devices connected to a network of network devices, and may receive network data identifying network metrics associated with the network devices. The device may generate an active queue management mapping table based on utilizing a model to process the explicit congestion notification data and the network data. The device may determine, based on the active queue management mapping table and the network data, a routing table that includes routing data identifying traffic paths with active queue management enabled network devices and without non-active queue management enabled network devices of the network devices. The device may provide the routing table to the network devices.
Radio Access Network Congestion Response
A response that preemptively mitigates an effect of a predicted network congestion event is disclosed. A machine learning or artificial intelligence model or process (ML/AI), that can be updatable, can be used to predicting congestion. Key performance indicators can be analyzed in accord with the ML/AI to predict, infer, etc., a characteristics of a congestion event. The analysis can be performed in near-real-time, typically with delays less than one second, but generally more than 10 milliseconds. The ML/AI, or update thereto, can be determined in non-real time, typically with delays greater than one second. A prediction of a congestion event can trigger operations that cause a user equipment to suspend use of a radio access network node, generally by shifting communications to another wireless node, access point, etc. An embodiment of the disclosed subject matter can be embodied via a virtual radio access network component.

DETERMINING RATE DIFFERENTIAL WEIGHTED FAIR OUTPUT QUEUE SCHEDULING FOR A NETWORK DEVICE
A network device may receive packets and may calculate, during a time interval, an arrival rate and a departure rate, of the packets, at one of multiple virtual output queues. The network device may calculate a current oversubscription factor based on the arrival rate and the departure rate, and may calculate a target oversubscription factor based on an average of previous oversubscription factors associated with the multiple virtual output queues.
