  • Patent number: 10187475
    Abstract: A method and system for automatically bypassing a network proxy in the presence of interdependent traffic flows. Messages from a client attempting to establish communication with an origin server are monitored to detect the presence of certain state information. If the origin server is present in one or more bypass lists, the network proxy is bypassed and communication is established between the client and origin sever directly. Otherwise, communication between the client and origin server is established though the network proxy. Messages between at least the origin server and client are monitored in order to identify origin servers for which the network proxy should be bypassed. The bypass lists are automatically updated for such origin servers.

    Abstract: A system for creating a session entry and forwarding an IP packet includes memories that store session and session template tables, and first and second processors in communication with the memories. When the first processor receives the IP packet, it determines whether the session table includes a session entry corresponding to the IP packet. If the session table does not include the session entry, the first processor determines whether the session template table includes a session template entry corresponding to the IP packet. The first processor generates the session entry using the session template entry and the IP packet. If the session template table does not include the session template entry, the first processor forwards the IP packet to the second processor, which generates the session template entry and the session entry.

  • Patent number: 9167616
    Abstract: A system, method and mobile device for initiating a voice call from the mobile device is provided. An expiration time is determined based on a time reference synchronized with a mobile call server. The mobile device transmits to the mobile call server a session initiation protocol (SIP) call initiation request including a destination number and the expiration time. A second call initiation request to a secondary contact number is initiated to establish the voice call to the destination number, when a response to the SIP call initiation request is not received from the mobile call server prior to the expiration time enabling reliable establishment of the voice call when the first attempt is unsuccessful. The mobile device does not have to wait on the mobile call server to determine a call failure and ensure that subsequent call initiation by the mobile device does not result in a call establishment collision with the mobile call server.

  • Patent number: 9008087
    Abstract: A control system that includes several controllers for managing several switching elements. A first controller receives a request to modify a data tuple stored in a network information base (NIB) storage of the first controller that stores data for managing a set of switching elements. The first controller determines whether the received request to modify should be processed by the first controller. When the received request should be modified by the first controller, the first controller modifies the set of data in the NIB storage. The first controller updates a request list that is propagated between the controllers to disseminate requests to modify different data tuples that are stored in the NIB storages of the different controllers.
