  • Patent number: 10594766
    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.

  • Publication number: 20190387565
    Abstract: In one example, a method and apparatus for web browsing on multihomed mobile devices having multiple communication interfaces are disclosed. In one example, the method establishes a primary multiple path transmission control protocol subflow for the transfer of a resource from a server to a user endpoint device. The method then determines a threshold of resource size. When the size of the resource is determined to exceed the threshold, the method establishes a secondary multipath transmission control protocol connection that cooperates with the primary multiple path transmission control protocol subflow for the transfer of the resource from the server to the user endpoint device.

  • Publication number: 20190288935
    Abstract: A request for a chunk of data is received from an application executing on a remote device. The chunk of data is split into a plurality of packets including a first packet and a second packet. A first sub-flow is selected to transport the first packet to the remote device and a second sub-flow is selected to transport the second packet. The first sub-flow is decoupled from the second sub-flow. A first stop time is selected for the first sub-flow and a second stop time is selected for the second sub-flow. The first stop time determines when the first sub-flow will complete at the remote device and the second stop time determines when the second sub-flow will complete at the remote device. The first stop time and the second stop time are selected so that the first sub-flow and the second sub-flow will complete simultaneously at the remote device.

  • Patent number: 10375112
    Abstract: A system for decrypts encrypted Secure Sockets Layer (SSL) data from packet traces without using private keys or a proxy. Decryption of encrypted SSL data is accomplished by intercepting a session key associated with a communication session transmitted from a user device to a server during handshaking between the user device and the server. The session key is then used to decrypt packet level traces of the communication session. The decrypted packet level traces are then used to measure traffic.
