Patent number: 11838779Abstract: Systems and methods for managing traffic in a hybrid environment include monitoring traffic load of a local network to determine whether the traffic load exceeds or is likely to exceed a maximum traffic load, where the maximum traffic load is a traffic load for which a service can be provided by the local network, based on a license. An excess traffic load is determined if the traffic load exceeds or is likely to exceed the maximum traffic load. One or more external networks which have a capacity to provide the service to the excess traffic load are determined, to which the excess traffic load is migrated. The local network includes one or more service instances for providing the service for up to the maximum traffic load, and the service to the excess traffic load is provided by one or more additional service instances in the one or more external networks.Type: GrantFiled: December 20, 2021Date of Patent: December 5, 2023Assignee: Cisco Technology, Inc.Inventors: Balaji Sundararajan, Sanjay Kumar Hooda, Venkatesh Ramachandra Gota, Chandramouli Balasubramanian, Anand Oswal

Publication number: 20230188413Abstract: An enterprise controller of an enterprise network sends to a service gateway of a service provider network a request for network slice information about network slices provisioned on a data plane of the service provider network. Responsive to the sending, the enterprise controller receives from the service gateway the network slice information including identifiers of and properties associated with the network slices. Responsive to receiving a request for the network slice information from a network device at a border of a forwarding plane of the enterprise network, the enterprise controller sends the network slice information to the network device to cause the network device to perform configuring network traffic in the forwarding plane with identifiers of ones of the network slices that match the network traffic, and to perform forwarding the network traffic configured with the identifiers to the data plane of the service provider network.Type: ApplicationFiled: February 3, 2023Publication date: June 15, 2023Inventors: Oliver James Bull, Rex Emmanuel Fernando, Anand Oswal, Kausik Majumdar, Darren Russell Dukes, Sanjay Kumar Hooda
