Abstract: A method may include transmitting a first public encryption key from to a control device and encrypting a first packet for a remote network device utilizing a first private encryption key correlated with the first public encryption key. The method may also include generating a second public encryption key and a second private encryption key and transmitting the second public encryption key to the control device. The method may additionally include receiving a first message from the remote network device that the remote network device received the second public encryption key from the control device, and after receiving the first message from the remote network device that the remote network device received the second public encryption key, encrypting a second packet utilizing the second private encryption key.

Abstract: A method of routing network traffic may include determining a first data link preference configuration indicating a first preference order for a first plurality of data links over which a first network device communicates. The method may also include receiving a second data link preference configuration indicating a second preference order for a second plurality of data links over which a second network device communicates. The method may additionally include, based on a combination of the first data link preference configuration and the second data link preference configuration, determining a preferred data link to transmit data from the first network device to the second network device. The method may include transmitting data over the preferred data link from the first network device to the second network device.

Abstract: A server-side adaptive streaming capability is provided. The server-side adaptive streaming capability supports adaptive streaming of a data object from a server toward a client via a Transmission Control Protocol (TCP) connection between the server and the client. The server has access to a plurality of versions of the data object having a respective plurality of encoding bit rates associated therewith. The server has a TCP congestion control mechanism running for the TCP connection. The TCP congestion control mechanism has information associated therewith. The server determines, using the information associated with the TCP congestion control mechanism running on the server for the TCP connection, a transmission bit rate expected to be supported by the client for the TCP connection.
