  • Publication number: 20240422531
    Abstract: Security protocols and techniques are provided to reduce security risks posed by anomaly traffic in a WSN. The WSN includes a WSN base station that communicates with one or more IoT servers over a 5G network or other backbone network. The WSN is managed by a WSN Central Office. The WSN base station monitors IoT traffic based on a detection model trained at a central office and detects the presence of anomaly traffic. Responsive to the detection of the anomaly traffic, the WSBS triggers a reconfiguration of the WSN to create a special path for the anomaly traffic to minimize the impact of the anomaly traffic on the WSN. Additionally, the central office can request the 5G network to update the NSI allocation to dedicate a network slice instance (NSI) for the anomaly traffic to segregate the anomaly traffic from the normal IoT traffic in the 5G network.

  • Patent number: 11943284
    Abstract: An overload protection mechanism for network nodes in an edge node cluster uses two tier reinforcement learning models; one at the edge node level and one at the cluster level. The node level reinforcement learning model optimizes a routing policy for a service/application to determine whether an edge node receiving a client request shall handle the traffic for the service/application. The cluster level reinforcement learning model optimizes a policy for an application that determines which neighboring edge node shall be considered to handle a client request for the given application in case of redirection or proxy by the edge node receiving the client request.

  • Publication number: 20230129604
    Abstract: An open edge cloud platform (OECP) enables tenants to access resources of a pool of network operator to support tenant applications. The tenant can specify a virtual location when requesting creation of a virtual network for a tenant application. The OECP creates a virtual network for the tenant application from available resources of a pool of network operators at the virtual location specified by the tenant in the request. The flexibility of selecting resources from a pool of network operators enables the tenant to access resources closer to the end user devices that will use the tenant application and thus reduce latency for applications and increase data throughput.
