Abstract: Systems and methods are provided for dynamically routing packets using multi-flow and multi-path multiplexing connections. A first computing device and second computing device communicate via a plurality of data flows, which may be routed across various network paths. Each flow is defined by a set of network addresses, a set of ports, and a protocol specification, such as UDP. The second device sends information to the first device regarding the various data flows. The first device may send probing packets to facilitate collecting data flow information. Information may include latency, packet loss, and other values. Based on the information received, the first device may select or prioritize data flows to mitigate congestion, and address performance criteria. The first device may also transmit information regarding selected data flows to other devices, allowing the other devices to utilize a selected data flow even if they lack multiplexing capability.

Abstract: Techniques for efficient bandwidth estimation are described herein. In some cases, the bandwidth estimation techniques disclosed herein may, for example, calculate bandwidth based on multiple packet groups transmitted at different times. Additionally, in some cases, the bandwidth estimation techniques disclosed herein may, for example, capture cross traffic and its effects on bandwidth. Furthermore, in some cases, the bandwidth estimation techniques disclosed herein may, for example, employ dynamic self-correcting techniques for more reliable estimates.

Abstract: Techniques for adaptive content transmission are described herein. During transmission of a content item, a network connection may be monitored to collect data corresponding to one or more network conditions associated with the transmission of the content item. Such network conditions may include, for example, network throughput, available network bandwidth, network latency and others. The collected data may be used to dynamically adjust one or more transmission attributes in connection with the transmitted content item. The one or more transmission attributes may be determined for adjustment at any desired transmission interval.
