  • Publication number: 20220366409
    Abstract: The present application relates to a digital certificate processing method and system, a gateway, a device, a medium, and a program product. The digital certificate processing method is a distributed digital certificate processing method, which is applied to a gateway. The distributed digital certificate processing method includes: polling a digital certificate processing node to obtain latest digital certificate processing task template data; generating simplified task template data of a digital certificate processing task based on the digital certificate processing task template data; and distributing the simplified task template data to a digital certificate processing service device.

  • Patent number: 9258277
    Abstract: In general, techniques are described for performing decentralized packet dispatch. A network device comprising one or more service processing units (SPUs) and an interface may implement the techniques. The interface receives a packet associated with a session and selects a first one of SPUs to dispatch the packet based on first information extracted from the packet. The first one of the SPUs dispatches the packet to a second one of the SPUs based on second information extracted from the packet. The second one of the SPUs performs first pass processing to configure the network security device to perform fast path processing of the packet such that second one of the SPUs applies one or more services to the packet and subsequent packets associated with the same session without application of services to the packets by the first one of the service processing units.

  • Patent number: 8676159
    Abstract: In general, techniques are described for modifying control plane messages for subscriber sessions with a network device to add and/or modify discrete information elements and thereby conform the messages to different versions of mobile network specifications, including roaming protocols, executed by different mobile networks or by heterogeneous infrastructure elements within a mobile network. In some examples, an input network interface of a network device receives a roaming protocol message on an interface connecting a first support node of a first mobile network and a second support node of a second mobile network. A roaming protocol module of the network device modifies the roaming protocol message by adding or modifying a discrete information element to conform the roaming protocol message to a roaming protocol of the second mobile network. An output network interface of the network device sends the modified roaming protocol message to the second support node.
