Methods, systems, and devices for communications are described. One or more flows between a node and one or more other nodes in a communication network may be monitored over a time period. During the monitoring, it may be identified that, during a subset of the time period, communications over at least one of the flows were restricted by the communication network based on receiving at least one indicator of congestion for the at least one flow. A quantity of traffic communicated over the one or more flows during the subset of the time period may then be determined, and respective flow rates of the one or more flows may be obtained. The obtained flow rates may be used to calculate a data rate of one or more connections between the node and the one or more other nodes.

Passive measurement of communication flows

Described herein are systems and methods that dynamically manage network traffic for individual subscribers based on past and current data usage rates. The disclosed systems and methods operate to control data traffic for a group of subscribers that share a common access network or that share a common access link to an access network. Prior to an individual subscriber reaching their data plan limit, the disclosed systems and methods track individual subscribers' past and current data rates and manage individual subscribers' current usage rates so that each subscriber's continually or periodically updating past usage rate stays within a provisioning rate for the group. This can improve user experience because rather than waiting until a subscriber has reached their plan data limit to impose strict data usage restrictions, the disclosed systems and methods use modest restrictions continuously or intermittently during the plan period.

Managing data traffic in a subscription-based network access system

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

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 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.

Communication of congestion information to end devices

A device can receive, from a user device, a hypertext transfer protocol (HTTP) CONNECT request associated with a toll-free data service. The user device can establish a first transmission control protocol (TCP) connection with a proxy server. The HTTP CONNECT request can request the proxy server to establish a second TCP connection with a content provider server. The device can determine, based on the HTTP CONNECT request, that an authorization condition is satisfied. The device can store information associated with a flow between the user device and the content provider server. The user device and the content provider server can establish a transport layer security (TLS) connection based on the first TCP connection and the second TCP connection. The device can provide the information associated with the flow to permit an account of an entity to be adjusted in association with the toll-free data service.

Enabling hypertext transfer protocol (HTTP) connect in association with a toll-free data service

A method, a device, and a non-transitory storage medium are described in which a connection service is provided based on a software development kit architecture for an end device that operates with an Android operating system. The connection service includes a library that, when called, sets-up a Hypertext Transfer Protocol connection between the end device and a proxy device using a function pointer and a portable operating system interface connect function. The connection service also generates and transmits a Hypertext Transfer Protocol CONNECT message, which includes a Proxy-Authorization header, to the proxy device, which triggers three-way handshaking between the proxy device and a target device, subsequent to an establishment of the connection with the proxy device.

Redirection of data flows from an end device

A method, a system, and a non-transitory storage medium provide an IP address and port-based identity service in which an anchor node of a wireless network stores identity information pertaining to a user of a mobile device in a centralized database. An authenticated and authorized web server may query the centralized database using the IP address or the IP address and port of an end device connected to the web server. The web server may obtain identity information pertaining to the user, such as a mobile telephone number.

Internet protocol address and port-based identity service

An exemplary method includes a subsidized access management system detecting a request provided by an access device associated with a user to access network content by way of a secure connection within a network provided by a network service provider, the network content associated with a content provider and maintained by a content provider system, determining that a data usage charge for access by the user to the network content by way of the secure connection within the network is subsidized by the content provider in accordance with a subsidized access arrangement between the content provider and the network service provider, and providing the user with subsidized access to the network content by way of the secure connection within the network in accordance with a rule set associated with the subsidized access arrangement. Corresponding methods and systems are also disclosed.

Methods and systems for providing subsidized access to network content by way of a secure connection

A device can be configured to receive a transmission control protocol (TCP) packet from a user device and determine, based on data included in a header portion of the TCP packet, that the TCP packet includes a toll-free token. The toll-free token included in the TCP packet can be identified, an entity associated with the toll-free token can be identified, and an action can be performed based on the entity.

Toll-free data management

A device may identify a proxy connection associated with a first device and a second device. An application buffer of the proxy connection may be associated with a first buffer size for at least one of the first device or the second device. The proxy connection may be associated with a video communication. The device may determine a set of parameters relating to the proxy connection. The device may determine a buffer allocation for the proxy connection based on the set of parameters. The device may perform an alteration to the application buffer of the proxy connection to cause the application buffer of the proxy connection to be associated with a second buffer size. The second buffer size may be different from the first buffer size.
