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.

A method performed by a first node for flow control in a wireless communication system is provided. The method includes identifying a triggering event for transmitting downlink flow control feedback information, generating the downlink flow control feedback information including an available buffer size based on the identified triggering event, and transmitting, to a second node, a backhaul adaptation protocol (BAP) layer message including the downlink flow control feedback information.

A system and method for managing congestion in a multi-hop wireless network, employing congestion notification messages. The technology has three main components: a mechanism at the Medium Access (MAC) layer for determining when a given source or transit node is deemed congested; a mechanism at the Network Layer (NL) determining how to propagate this information to applications, including suitably combining overload indications received from neighbors; and a mechanism at the Transport Layer (TL) of each source of traffic for determining when a source is generating excessive traffic, and combining it with Medium Access Control (MAC)-based overload indication from downstream nodes, thus providing a multi-layer approach to traffic throttling.

Dynamic wireless network throughput adjustment is provided herein. A method can include determining, by a system comprising a processor, a sector of a communication network for which an amount of congestion present in the sector is greater than a congestion threshold; selecting, by the system from among respective network equipment operating in the sector, target network equipment for throughput adjustment based on equipment performance metrics respectively associated with the respective network equipment; and facilitating, by the system, adjusting a throughput of the target network equipment by an adjustment amount determined based on target equipment performance metrics, of the equipment performance metrics, associated with the target network equipment.

There is described a method for determining a play duration estimate of an adaptive bit rate (ABR) media presentation. The method comprises receiving at a network entity a media playlist manifest file of the media presentation, wherein the manifest file is transmitted from a content server to a client and comprises a plurality of entries, each entry linking to a respective different one of a plurality of media segments of the media presentation. The method further comprises determining a data size of the manifest file; and determining a play duration estimate of the media presentation based on the determined data size of the manifest file, a first value that represents a data size of each of the plurality of entries in the manifest file and a second value that represents a play duration of each media segment of the plurality of media segments of the media presentation.

A wireless transmit/receive unit (WTRU) may select a first type of buffer status information or a second type of buffer status information. The first type of buffer status information may indicate an amount of data buffered and the second type of buffer status information has less bits and is a different format than the first type of buffer status information. The WTRU may select, subsequent to a number of subframes of a transmission of buffer status information of a first type, buffer status information of the first type for transmission.

There is provided a method comprising: preparing a data packet for transmission on a bearer, wherein at least one of the following is configured for transmission: a first network node and a second network node, checking whether at least one predetermined criterion is met, selecting, based at least partly on the said checking, whether to transmit the data packet via the first network node, via the second network node, or via both the first and the second network nodes, and transmitting the data packet according to the selecting.

Embodiments are directed to a computer system for managing data transfer. The computer system includes a memory, a processor communicatively coupled to the memory, a send component and a receive component having a message queue and a controller. A link interface communicatively couples the send component to the receive component. The link interface includes a mainline channel and a sideband channel, and the computer system is configured to perform a method. The method includes transmitting mainline channel messages over the mainline channel from the send component to the receive component. The method further includes transmitting sideband channel messages over the sideband channel from the send component to the message queue of the receive component. The method further includes utilizing the controller to control a flow of the sideband channel messages to the message queue without relying on sending feedback to the send component about the flow.
