摘要： A system described herein may provide a technique for selecting and configuring a capture component and a filtering and analysis component for traffic capture in a manner that suitably accounts for Service Level Agreements (“SLAs”) of traffic to be captured. A traffic capture request may indicate one or more SLAs and/or other attributes, and an orchestration system may identify a network function (such as a User Plane Function (“UPF”) of a wireless network) that handles traffic that includes the requested traffic and instantiate the capture component at a node that implements the network function. The orchestration system may select a node, from a cluster of nodes, that is able to filter and analyze the traffic in an expedient manner in accordance with SLA(s) associated with the requested traffic, and install the filtering and analysis component at the selected node.

摘要： A network device receives, from a congestion controller, traffic policy information associated with a data stream between a sender and a receiver, where the traffic policy information includes a maximum round trip delay time (RTT) and a maximum throughput rate (Rate). The network device obtains a receiver advertised window size (RWND) for the receiver for the data stream. The network device modifies the RWND based on the RTT and the Rate to produce a modified receiver window size (RWND′) and sends the RWND′ to the sender for use in controlling congestion on the data stream between the sender and the receiver.

摘要： A device may determine one or more round-trip time threshold values and may determine a round-trip time value associated with a flow. The device may determine a smoothed round-trip time value based on the one or more round-trip time threshold values and the round-trip time value. The device may determine a congestion window threshold value based on the smoothed round-trip time value and may determine a congestion window value based on the congestion window threshold value. The device may provide traffic associated with the flow based on the congestion window value.

摘要： A system can receive an indication associated with establishing a transmission control protocol (TCP) connection. The system can determine, based on the indication, information that identifies a user device associated with the TCP connection. The system can determine, based on the information that identifies the user device, a predicted congestion level of a base station associated with the TCP connection. The system can select, based on the predicted congestion level, a congestion control algorithm to be implemented for the TCP connection. The system can cause the TCP connection to be established and implement the congestion control algorithm for the TCP connection.

摘要： Systems and methods for pacing data transmission are described. An illustrative method includes transmitting, by a network device, a data stream at a pacing rate to a user equipment (UE) device. The method further includes accessing a metric of a radio access network (RAN) to which the UE device is connected, the metric associated with the UE device. The method further includes adjusting, based on the metric, the pacing rate at which the data stream is transmitted to the UE device.

摘要： Methods, devices, and storage mediums select an edge network site over other candidate edge network sites, to resolve hostnames, from end devices, to Internet protocol addresses based on various network path information, over other factors, such as a proximity of the end device to the selected edge network site relative to the proximity to the other candidate edge network sites.

摘要： A network device predicts end-to-end channel capacity entropy to permit use of optimal throughput settings in a network. The network device stores class definitions for a network condition; identifies multiple input features to correlate with the class definitions; generates a multiclass classification model that produces an importance score for each of the multiple input features, wherein the importance score reflects the contribution of an input feature to the network condition; selects two or more of the multiple input features with highest importance scores as influential features; predicts the behavior of the influential features to identify a current class, from the class definitions, for the network condition over an end-to-end communication channel; and sends an estimated network condition, based on the current class, to a device for traffic optimization.
