  • Publication number: 20260223206
    Abstract: Novel tools and techniques are provided for implementing programmable protocol-independent session processor (“PPSP”)-based communications. When a computing system determines that a first administrative domain and a second administrative domain require different signaling protocols to establish communication sessions for user devices in the two administrative domains, the computing system may convert one or more signaling protocols used by the two administrative domains into a common signaling protocol, and may establish an end-to-end (“E2E”) real-time communication session between the user devices in the two administrative domains, using the common signaling protocol.

  • Patent number: 12693925
    Abstract: Novel tools and techniques are provided for implementing real-time fault management or real-time fault management system (“RFM”). In various embodiments, RFM may receive alerts from or associated with network devices (e.g., layer 2, 3, and/or 4 devices, or the like) that are disposed in a plurality of disparate networks that may utilize different alert management protocols and/or different fault management protocols. RFM may collect, enrich, normalize, aggregate, and display the alerts in a user interface to facilitate addressing of the alerts by a user. To enable continuous and real-time functionality, RFM may be implemented in a plurality of siloed platforms in a primary data center, with processing of alerts being load balanced across the siloed platforms, with mirrored group of siloed platforms in a secondary data center located geographically distant from the primary data center and configured to be on “hot standby” and to completely take over RFM processing operations.

  • Patent number: 12695763
    Abstract: Apparatus, systems, methods, and the like, for autonomous scaling of security and other network services through initialization of a service from a network service device and/or migration of such services from one service device to another is provided. Such network scaling may allow for migration of services from existing service edges to other service edges. A security management system may coordinate the migration of services provided to a secondary network from one or more service edges to another, separate service edge while providing session synchronization during the migration. To migrate the services from the first service edge to a second service edge, a session table may be shared between the service edges and the first and second service edges may advertise service routes or endpoints with one or more priority values to control or otherwise determine which service edge is selected by a service-receiving device to receive the services.

  • Patent number: 12695690
    Abstract: A method is disclosed for testing network devices for networks with a large traffic load utilizing one or more traffic load amplifiers to amplify the traffic load. The load amplifiers connected to the device may receive packets of an initial traffic load, multiply or copy the received packet, alter the destination address information in the header of the copied packets to generate packets with different destination addresses, and transmit the altered packets back to the device for further routing. The altered or copied packets may then be routed via the device back to the load amplifier for further amplification. Through this amplification process, a small initial load of packets may be amplified over and over by the load amplifiers until a target traffic load is achieved at the device to test the device performance at a large traffic load.

  • Publication number: 20260211760
    Abstract: Novel tools and techniques are provided for implementing intelligent alert automation ("IAA"). In various embodiments, IAA receives alert/event feeds from several different alerting and ticketing systems via input Redis queues, and uses a triage system to determine whether to process the alert/event or disregard it. If so, IAA may create a flow instance, assign a unique instance ID, and place the flow instance in one of a plurality of jobs queues based on alert/event type and/or or source. An abattoir system retrieves a flow instance from one of the jobs queues (in order of the queue's priority), and processes the next node or step in the flow instance. The flow instance is placed back into the jobs queue for subsequent processing by the same or different abattoir system until no additional nodes or steps remain in the flow, at which point the flow instance is considered complete.

  • Publication number: 20260214085
    Abstract: Systems and methods for enforcing compliance-program conformity during authorization-token generation are presented. Applications may be registered with an identity and access management (IAM) system. The registration of the application may include whether the application is subject to one or more compliance program(s). When an authorization token is requested from the IAM system, the IAM system may (a) determine the set of authorization information needed in the token, and (b) determine whether the application is subject to a compliance program. The IAM system may then check an approval source of record to determine whether the user was legitimately approved for the required authorization prior to granting an authorization token. If there is a mismatch between the approval source of record and the authorization information associated with the user identity, then the mismatch may cause certain mitigation actions to be performed.

  • Patent number: 12689610
    Abstract: Implementations include providing security services to workloads deployed across various types of network environments, such as public networks, private networks, hybrid networks, customer premise network environments, and the like, by redirecting traffic intended for the service device through a security environment of the first network. After application of the security features to the incoming traffic, the “clean” traffic may be transmitted to the service device instantiated on the separate network via a tunnel. Redirection of incoming traffic to the security-providing first network may include correlating a network address of the service device to a reserved network address of a block of reserved addresses and updating a Domain Name Server (DNS) or other address resolving system with the reserved address. The return transmission tunnel may be established between the security environment and the network address of the service device.

  • Patent number: 12684072
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products for consolidating toll-free and/or tolled features of two or more telecommunications networks. The networks may be consolidated via an Enhanced Feature Server (EFS) deployed in a telecommunications network. The EFS may be configured to receive a toll-free and/or tolled communication and route the communication based on the dialed toll-free number and a carrier identification code (CIC) associated with the communication, or based on the dialing number and a CIC. Routing the communication based at least on the CIC associated with the communication allows the telecommunications network to consolidate a redundant network from the telecommunications network. In circumstances where a CIC is not associated with a communication, the EFS may request a data schema from a toll-free database, or from an automatic number identification (ANI) database, and determine a CIC based on an analysis of the data schema.

  • Publication number: 20260189500
    Abstract: Novel tools and techniques are provided for implementing name-based routing through networks. In various embodiments, a broker manager in each of a plurality of networks may receive a subscription request for a network device from a client device, each device being locally accessible or disposed in an upstream or downstream network. The broker manager uses its client broker to communicate with a locally accessible client device, and uses its mediator broker (and, sometimes, an intermediate device(s)) to communicate with a locally accessible network device. The broker manager otherwise uses its messaging brokers to communicate with control channels of one or more networks. Once subscription with the network device has been established, any commands and responses between the client device and the network device may be routed over pub/sub channels via the broker managers and their brokers using name-based routing, without routing based on IP address of the network device.
