Abstract: A system and method for cooperative data streaming are disclosed. According to one embodiment, a system for cooperative data streaming comprises a group of devices comprising at least two devices, which are interested in obtaining the same content from the same server. Each device comprises one or more primary network interfaces connecting the device to the data streaming service and one or more secondary network interfaces connecting the device to one or more of the other devices through one or more wireless local networks. The primary network interfaces are configured for connecting the devices to the data streaming service for receiving at least segments of data. The secondary network interfaces are configured for mutually connecting said devices in order to locally exchange said received segments of data.

Abstract: Methods and apparatuses to model the relation between the delay samples and congestion losses and to protect media flows against congestion losses are disclosed. In one embodiment, the method comprises measuring congestion by delay samples, and performing a dynamic FEC algorithm that uses convex hull clustering for loss-event classification, including determining an FEC rate according to the loss-event classification. In another embodiment, the method comprises measuring congestion by delay samples, modeling loss events associated with the delay samples by grouping loss events as unions of convex hulls to identify a period of potentially increased congestion, dynamically changing the FEC rate based on the modeling, and applying FEC protection to the media flow during the period based on the FEC rate.
