  • System and method of lightweight decentralized NFV orchestration
    Patent number: 10761896
    Abstract: In one embodiment, a network functions virtualization infrastructure can be managed in a decentralized fashion. A front end can receive a request to provision a virtualized network function. The front end can create service descriptors for the request according to the virtualized network function, the service descriptors comprising a hierarchy of information elements organized based on distributed back-end agents operable to provision and manage the virtualized network function. The front end can store the service descriptors in a distributed data store.
    Type: Grant

  • Datapath triggered on-demand NFV service activation
    Patent number: 10476839
    Abstract: Systems and methods for triggering service activation include starting a vCPE instance in response to a request for a service, instantiating a service container for the requested service and starting the service in the service container, installing a fast path entry for the service container in a local bridge table, detecting an idle timeout of the service and labeling the local bridge table entry for the corresponding service container as inactive, notifying a cloud services manager that the service container is inactive, and removing the service container.
