Alternate Path Routing Patents (Class 709/239)
  • Patent number: 10708348
    Abstract: Methods and systems for high-availability data processing include detecting, at a first data processing system, a change in link state between the first data processing system and a second data processing system. A link state between the first data processing system and a third data processing system is changed responsive to the detection in accordance with a first high availability policy stored at the first data processing system. An identifier of the first data processing system is changed in accordance with the first high availability policy to conform to a second high availability policy stored at the first data processing system. The detection, change of the link state, and change of the identifier are repeated in accordance with the second high availability policy.

  • Patent number: 10671721
    Abstract: A scalable, threat detection system features computing nodes including a first computing node and a second computing node operating as a cluster. Each computing node features an analysis coordinator and an object analyzer. The analysis coordinator is configured to conduct an analysis of metadata associated with a suspicious object that is to be analyzed for malware, where the metadata being received from a remotely located network device and to store a portion of the metadata within a data store. The object analyzer is configured to retrieve the portion of the metadata from the data store, monitor a duration of retention of the metadata in the data store, and determine whether a timeout event has occurred for the object associated with the metadata based on retention of the metadata within the data store that exceeds a timeout value included as part of the metadata associated with the suspicious object for malware.

  • Patent number: 10666724
    Abstract: Multiple geo-replicated and independent IoT (Internet of Things) hubs configured as servers with storage capacities are utilized and span across various regions in the world, to each of which IoT devices can connect and transmit telemetry data. The IoT devices, configured with sensors to generate telemetry data (e.g., temperature, pressure, etc.), can fail over to another geo-replicated IoT hub (the “target geo-replicated IoT hub”) when one IoT hub experiences technical failures or the IoT device changes location to a region which is covered by the target IoT hub. Upon receiving a connection request from the IoT device, the target geo-replicated IoT hub submits a proposal to available geo-replicated IoT hubs for ownership over the IoT device, that is, receive data from and transmit messages to the IoT device. A quorum is sought so that all IoT hubs are in agreement as to a current owner of the IoT device.

    Abstract: The present disclosure involves systems, software, and computer implemented methods for event processing in background services. One example method includes receiving a request to create a daemon session, the request including at least one parameter. The session is created, including storing the at least one parameter in a memory storage that is configured to survive a restart of the session. A set of messages is received for the session. The messages are stored in a queue that is configured to survive a restart of the session. A determination is made that the session is to be restarted. A restart of the session is initiated, including providing the at least one parameter to the session during the restart of the daemon session and providing unprocessed messages to the session after the session has been restarted, to enable the session to process the unprocessed messages.

  • Patent number: 10594592
    Abstract: BGP can advertise multiple routes for same prefix via BGP add path (RFC 7911). BGP attempts to pack prefixes with same path attributes into the same BGP update message. Protocol nexthop is one of the path attributes. Since these BGP add paths routes usually have different protocol nexthops, different routes for a single prefix could end up being spread out when being advertised. That may, in turn, result in additional calls to download routes to FIB, advertisement to peers and multiple runs of multipath calculation for the same prefix when multipath is configured. To help avoid this situation, when BGP advertises add-path routes, BGP can send the multiple paths for the same prefix in the adjacent update messages. BGP can use extended Network Layer Reachability Information (NLRI) field to carry nexthop along with its associated prefix in BGP update message to send plain IPv4 unicast routes.

Cellular telephone network equipment may communicate with a cellular telephone over a data connection. The cellular telephone may have an internet protocol (IP) address that allows data to be provided to the cellular telephone over the data connection. To conserve resources and release unused IP addresses, the cellular telephone network equipment may deactivate inactive data connections after a period of inactivity. A baseband processor within a mobile device may periodically send User Datagram Protocol (UDP) keep-alive packets over the data connection to ensure that the data connection remains active. The keep-alive packets may be directed to a packet sink server or may be associated with a black hole route. An applications processor in the telephone may remain in sleep mode during keep-alive packet transmission to conserve power.

The activation of software containers and tenants may be managed by maintaining an activation queue for storing requests to activate software containers or tenants on a host computer. Requests may be retrieved from the queue and utilized to determine whether a software container or a tenant is to be activated on a host. “Bounce” or hot swap tenant activations may be performed. Tenant activation requests might also be throttled by denying the requests or by postponing the requests until a later time. A software container might also be configured to throttle incoming requests to tenants executing therein.

    Abstract: In an example, a network switch is configured to natively act as a high-speed load balancer. Numerous load-balancing techniques may be used, including one that bases the traffic “bucket” on a source IP address of an incoming packet. This particular technique provides a network administrator a powerful tool for shaping network traffic. For example, by assigning certain classes of computers on the network particular IP addresses, the network administrator can ensure that the traffic is load balanced in a desirable fashion. To further increase flexibility, the network administrator may apply a bit mask to the IP address, and expose only a portion, selected from a desired octet of the address.

  • Patent number: 10230570
    Abstract: A Multi-Homing System is equipped with an Adaptive JSP Access Cloud State Detection apparatus (ACSD) that improves the reliability of the availability of digital connections (links) between computer sites, such as a Computer Premises Network and the Internet, in which such connections are made by connecting through a multiplicity of ISP Access Clouds (links). Reliability is improved over prior art methods by using data elements of Internet Protocol datagrams, e.g. record fields or bits of fields, that are regularly and normally exchanged between the ISP Access Clouds and the CPN without creating additional data traffic. Data Elements from each ISP Access Cloud are used by processing functions of the by the ACSD to test for conditions that indicate that it may be in a DOWN status.

  • Patent number: 10176044
    Abstract: A method includes determining that a primary delegate device is unavailable. The method continues by identifying a fallback delegate device for changing a node of a hierarchical index structure using a deterministic function. The deterministic function includes performing a first modification of global namespace address of the unavailable primary delegate device to produce a first modified address identifier. The deterministic function further includes determining whether another delegate device of the plurality of delegate devices has a global namespace address corresponding to the first modified address identifier. When the global namespace address of other delegate device corresponds to the first modified address identifier, the method further includes processing a change to a node of the one or more nodes via the other delegate device as the fallback delegate device.
