Abstract: Example implementations relate to virtual persistent volumes. In an example, a storage virtualization system receives performance metrics related to usage of a virtual persistent volume by a containerized application. The performance metrics are identified in an application data store profile, and the application data store profile is identified based on an application manifest of the containerized application. The virtual persistent volume is modified based on an analysis of the performance metrics.

Abstract: Example implementations relate to virtual persistent volumes. In an example, a storage operation request includes a volume identifier. A volume mapping that corresponds to the volume identifier is identified. Underlying volume identifiers are identified based on the volume mapping. The underlying volume identifiers relate to underlying storage volumes that form at least part of a virtual persistent volume associated with the volume identifier. The storage operation request is relayed, using the underlying volume identifiers, to storage systems on which the underlying storage volumes are respectively located.

Abstract: Example implementations relate to virtual persistent volumes for containerized applications. In an example, a plurality of different storage mounts are acquired from a mix of storage types. A containerized storage virtualization system creates and manages a virtual persistent volume that aggregates the acquired storage mounts. A mount point of the virtual persistent volume is provided to the containerized application. The virtual persistent volume includes a hierarchical structure that relates data objects of the containerized application by content-based signatures to a root object.

Abstract: Example implementations relate to virtual persistent volumes. In an example, a virtual persistent volume storage class is presented to a container orchestrator that includes parameters describing an associated virtual storage policy. In response to a provisioning request that identifies the virtual persistent volume storage class, a virtual persistent volume is created by determining a mapping of the parameters of the virtual persistent volume storage class to parameters of available storage classes so that the parameters of the virtual persistent volume storage class are fulfilled. At least one volume is provisioned to constitute the virtual persistent volume, according to the mapping.

Abstract: A method and apparatus for quickly determining the status of a network device in a network communicates status inquiry messages over the forwarding plane of one network device to at least one neighboring network device. The status inquiry messages indicate the connectivity status with at least one neighboring network device.

Abstract: A system, device, and method for receiver access control in an interne television system uses a push mechanism to distribute access control information from a distribution device to an access device. The access device uses the access control information to make receiver access control decisions for a subsequently received request from a host to join a television channel multicast group.

Abstract: A system, device, and method for distributing link state information in a communication network combines a link state routing protocol with a sliding window mechanism in order to efficiently distribute link state information. The sliding window mechanism permits a predetermined number of unacknowledged link state advertisement protocol messages to be outstanding at any given time. Unacknowledged link state advertisement protocol messages are retransmitted after a predetermined timeout period.

Abstract: A system, device, and method for distributing access control information in a communication system uses a reliable multicast mechanism for distributing access control information by a main server to multiple access control devices. A dedicated multicast group is established for distributing the access control information, and each access control device joins the dedicated multicast group. A reliable multicast mechanism is used to distribute the access control information to the multicast group members. Each access la control device obtains the access control information using the reliable multicast mechanism, and stores the access control information in a database for later use in making receiver access control decisions.

Abstract: A system, device, and method for receiver access control in an internet television system uses a push mechanism to distribute access control information froth a distribution device to an access device. The access device uses the access control information to make receiver access control decisions for a subsequently received request from a host to join a television channel multicast group.
