Abstract: A more efficient network can be achieved by using a cost-benefit analysis determined by mobile device, wireless network, and server device functionality. The cost-benefit analysis can be used to determine whether SPTCP or MPTCP or any combination of the two is used. The mobile device can generate the cost-benefit analysis based on known and unknown device and network metrics and send the cost-benefit analysis to the server device. The server device can then comply with the cost-benefit analysis and then send requested web site data via SPTCP and/or MPTCP in accordance with the cost-benefit analysis.

Abstract: A multimedia conferencing service uses accessible-forwarding-plane network elements such as OpenFlow® controllers and OpenFlow®-enabled switches. A conferencing server receives a conference subscription request including a network address of a L2/L3 signaling server, and connects to an accessible-forwarding-plane controller to control an accessible-forwarding-plane switch. Flow tables and group tables are managed to classify traffic with minimum table usage and update frequency. Media channels are established between clients through the OpenFlow®-enabled switches, relieving bottlenecks at the conferencing server.

Abstract: Aspects of the subject disclosure may include, for example, a process that determines a field-of-view of an immersive video viewer, determines present orientation of the immersive video viewer at a first time, and predicts a future orientation of the immersive video viewer occurring at a second time based on the present orientation of the immersive video viewer. A subsegment of an entire immersive video frame corresponding to the second time is identified based on the predicted orientation of the immersive video viewer and the field-of-view. Wireless transmission of the subsegment of the entire immersive video frame to the immersive video viewer is facilitated for presentation at the immersive video viewer at the second time, without requiring transmission of the entire immersive video frame. Other embodiments are disclosed.

Abstract: Leveraging multiple network interfaces, such as Wi-Fi and cellular, on mobile devices can improve user experience for various applications. Deadline-aware MPTCP scheduling can complement existing MPTCP scheduler. The deadline-aware MPTCP scheduler can dynamically select transmission paths to minimize cellular usage while satisfying data transfer deadlines. The deadline-aware MPTCP scheduler can also address several challenges, such as determining the appropriate traffic pattern over cellular paths, designing proper APIs between MPTCP and applications, and making the scheduler functionality robust and lightweight.

Abstract: When traffic arrives from the network for an idle mobile device, the network executes device activation procedures to awaken the device, which can result in a significant amount of signaling to complete. Adaptive device activation mechanisms are provided that adapt to network conditions and potentially to machine-to-machine device application requests to realize scalable device activation without increasing the resources used for this purpose and without negatively impacting existing human-to-human or human-to-machine traffic.

Abstract: A method includes receiving at a directory server a notification from a client system, where the notification indicates that the first client received a corrupt packet of a playfile from a first peer. The method also includes determining if the first peer is a poor quality peer, updating a first peer score for the first peer if the first peer is not a poor quality peer, identifying a second peer that is not on a blacklist, and providing a peer identification associated with the second peer to the client system.
