A system may include a first network device. The first network device may include a first processor configured to: obtain a copy of a first message sent from an application on a User Equipment device (UE); construct a signature based on the copy of the first message; and send a second message including the signature to a second network device. The second message may request the second network device to either train a classification model or to provide a device type of the UE or an application type of the application to the first network device.

HTTP/3 and QUIC-based device and application characterization

A device may include a processor configured to detect that a communication session in a private cellular wireless network is associated with an application and determine that data units associated with the communication session match a network slicing rule associated with the private cellular wireless network. The processor may be further configured to classify the communication session to a network slice based on the network slicing rule and assign the data units associated with the communication session to the network slice.

Systems and methods for automatic application-level network slicing over private cellular networks

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.

Systems and methods for congestion control on mobile edge networks

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.

A user device may measure unidirectional latency of applications over asymmetric links. The user device may accurately measure application level unidirectional latency over cellular networks, without synchronizing system clocks. The user device may accurately measure the unidirectional latency in both an uplink direction and a downlink direction, without using a high-precision system clock and without synchronizing clocks between the user device and an application server.

Systems and methods for measuring unidirectional latency of applications over asymmetric links

A network device includes a network interface for establishing a communication session with another network device, a memory to store instructions, and a processor to execute the instructions. The processor may, for each time period during the communication session, adjust a size of a receive buffer of a socket. When the processor adjusts the size, the processor, if a utilization number of the receive buffer is greater than a high threshold: may determine a first new size for the receive buffer, and set a size of the receive buffer to the first new size. If the utilization number is less than a low threshold, the processor may determine a second new size for the receive buffer; and set the size of the receive buffer to the second new size.

Controlling socket receive buffer for traffic optimization

A method, a device, and a non-transitory storage medium are described in which a network performance optimization service is provided. A load balancer device may receive, from an end device, an application service request for an application service that is available from multiple server devices of an application layer network. The load balancer device may determine, from a source identifier associated with the end device and obtained from the application service request, that the source identifier does not map to a network traffic forwarding rule of a set of stored network traffic forwarding rules. In response, the load balancer device may map the source identifier to an application service profile of a set of stored application service profiles; select, based on the application service profile, a first server device of the multiple server devices and establish the first server device to be the destination of the application service request.

Method and system for network performance optimization service

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.

Dynamic congestion control algorithm selection in a proxy device

Techniques for reducing network congestion are disclosed. In one embodiment, a method is disclosed comprising receiving, by a computing device, a packet from a sender over a network; retrieving, by the computing device, congestion information; inserting, by the computing device, congestion data representing the congestion information into a header option of the packet to generate an augmented packet; transmitting, by the computing device, the augmented packet to a receiver; receiving, by the computing device, a response packet, the response packet including the congestion data; and transmitting, by the computing device, the response packet to the sender.

Transparent quantitative congestion control

A wireless network device can receive, at a traffic director in a kernel space, a data packet from a client device and determine whether the data packet is intended for an application cloud server operating in a cloud environment. The wireless network device can provide, based on determining that the data packet is intended for the application cloud server, the data packet to an application server instance executing on the wireless network device. The application server instance can be implemented in a virtualized software container in a user space, and can be configured to perform one or more operations associated with the application cloud server. The wireless network device can receive, at the traffic director and from the application server instance, a result of the application server instance performing the one or more operations on the data packet, and transmit the result to the application cloud server.

Mobile edge computing

A method, a device, and a non-transitory storage medium are described in which a global identification service is provided. The service includes a selection of an Internet Protocol version 6 (IPv6) address to an end device. The service encrypts a unique identifier of the end device with an encryption key to generate an IPv6 address. The service verifies whether the IPv6 address is an IPv6 address allocated to or owned by a service provider. When the IPv6 address is an allocated or owned IPv6 address, the IPv6 address is assigned to the end device. When the IPv6 address is not an allocated or owned IPv6 address, the service selects another encryption key until a suitable IPv6 address is generated. Subsequent to an assignment of the IPv6 address, a network uses the IPv6 address as a globally unique identifier for the end device.

Global identification of devices based on designated IPv6 address

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&#x2032; to the sender for use in controlling congestion on the data stream between the sender and the receiver.

A computing device may include a memory configured to store instructions and a processor configured to execute the instructions to identify a data connection from an application server device to a user equipment (UE) device, wherein the UE device is connected to the network via a wireless connection; determine a target sending rate for the data connection; determine a round trip time for packets associated with the data connection; and calculate a send buffer size for the data connection based on the determined target sending rate and the determined round trip time. The processor may be further configured to set a send buffer size for a socket associated with the data connection to the calculated send buffer size and control a send rate from the application server device to the UE device for the data connection using the set send buffer size for the socket.

Flow level pacing by controlling socket send buffer size

A method, a device, and a non-transitory storage medium are described in which congestion control service is provided. The congestion control service may include determining whether congestion exists relative to packets and a queue of a network device. The congestion control service may include estimating a communication metric value when congestion exists. A differentiated service field of an Internet Protocol header of each packet is used to carry a portion of the communication metric value. The congestion control service transmits the packets, which include the communication metric value, to an end device. The end device may use the communication metric value to adjust a transmission rate of subsequently transmitted packets.
