Network devices may be configured to execute computer-executable instructions to instantiate a deployable unit based on the instructions. The instructions may include a virtual network function (VNF) template that includes: a virtualized deployment unit (VDU) template that describes the deployable unit that includes containers; and a connection point template bound to the VDU template. The deployable unit may provide services of a network function in an access network or a core network. The deployable unit may include an interface defined by the connection point template.

Systems and methods for modeling container-based network functions

A system may receive a first definition for a virtualized instance of a network function. The first definition may include a first set of declarations in a first format that is different than respective formats supported by different virtualized environments. The system may select a first virtualized environment to run the virtualized instance based on requirements specified within the first definition, and may generate a second definition with a second set of declarations that map the first set of declarations from the first format to a second format supported by the first virtualized environment. The system may deploy the virtualized instance to the first virtualized environment using the second set of declarations from the second definition. Deploying the virtualized instance may include configuring its operation based on some of the second set of declarations matching a configuration format supported by the first virtualized environment.

Systems and methods for multi-cloud virtualized instance deployment and execution

A Network Functions Virtualization (NFV) system reads, from a data bus coupled to the NFV system, Virtual Network Function (VNF) parameters published to the data bus by a new VNF. The NFV system publishes, to the data bus based on the VNF parameters, instructions to multiple components of the NFV system defining which VNF capabilities of the new VNF are to be managed, controlled, or monitored by which of the multiple NFV system components. The multiple components of the NFV system control, manage, or monitor the new VNF based on the published instructions. The data bus can include a Data Movement as a Platform (DMaaP) system that publishes and subscribes to streams of records.

Virtual network function bus-based auto-registration

An inter-bus hub, within a hierarchical data bus system, has a partitioned log that includes a first partition and a second partition, where the inter-bus hub is coupled to a first data bus residing in a first segment and to a second data bus residing in a second segment. The inter-bus hub aggregates, based on at least one set of rules, first data from the first data bus, and stores the first data in the first partition. The inter-bus hub aggregates, based on the at least one set of rules, second data from the second data bus, and stores storing the second data in the second partition. The inter-bus hub relays the first data from the first partition to a first destination and relays the second data from the second partition to a second destination.

Managing file objects in a data storage system includes providing a plurality of metadata servers, each metadata server having information for only a subset of file objects in the storage system, each subset for each of the metadata servers being less than a total number of file objects for the system and includes providing at least one metadata location server, where an entity accessing a specific file object of the system determines which of the metadata servers contains data for the specific file object by first accessing the at least one metadata location server. Information for the subset of file objects may include a table having file identifiers and metadata location information. The metadata location information may point to data storage for a metadata object for a file.

Managing file objects in a data storage system

A system and method of operation is disclosed describing migration, management, and operation of applications and servers from customer data centers to cloud computing platforms without modification to existing environments or user access procedures. A cloud isolation layer operates as a virtual layer on the cloud platform, enabling server operation in a virtual environment that appears the same as the prior local environment. A cloud software image and a local cloud gateway act to redirect existing addressing from the local environment to the cloud implementation through secure network and data paths. A local management application provides a control interface and maps and manages the local environment and utilized cloud resources.

Environment preserving cloud migration and management

Tracking storage resources includes providing a table containing storage resources along with capabilities and statuses thereof, updating the table in response to a change of status of a storage resource, updating the table in response to a change in capabilities of a storage resource and, in response to an inquiry for a storage resource having a particular capability, searching the table for a storage resource having the particular capability. Tracking storage resources may also include adding an element to the table in response to a new resource being added to the system. The capabilities may include RAID striping, data deduplication, and green operation. The status may be one of: on-line, off-line, and full.

Exposing storage resources with differing capabilities

Logging messages includes providing a logging subsystem that performs logging tasks, providing a log message database that contains log messages that are accessed according to a token value and providing calls to the logging subsystem, where a preprocessor modifies source code to replaces in-line text string parameters with tokens corresponding to the text string parameters. The in-line text string parameters may be log messages. The log message database may be coupled to the logging subsystem and the logging subsystem may access the log messages using the tokens. The preprocessor may determine if an in-line text message already exists in the log message database and, if not, may create a new entry for the in-line text message in the log message database.

Managing files using layout storage objects

This invention is a system and method for managing one or more data storage networks using a new architecture. A method for handling logical to physical mapping is included in one embodiment with the new architecture. A method for handling errors is included in another embodiment with the new architecture.

System and method for managing storage networks and providing virtualization of resources in such a network

Handling writing new data includes creating a journal entry that points to a first storage location containing old data to be replaced by the new data, where the journal entry is maintained after writing the new data, allocating new storage space having a second storage location, and writing the new data to the new storage space at the second storage location. The storage space may be provided by at least one storage device. Allocating new storage space may include remapping a switch coupled to the at least one storage device. The new data may be written by a host coupled to the switch. The switch may present the host with a logical storage area that is created by the switch mapping to different locations of the at least one storage device. The mapping may be transparent to the host. The switch may include at least one processor and a corresponding memory. The journal entry may be part of a journal that is stored in the memory. The storage space may correspond to a disk array storage device. The journal entry may be stored in the disk array storage device. The journal entry may be stored outside the disk array storage device. Allocating new storage space may include remapping a switch coupled to the disk array storage device and where the journal entry is stored on the switch. Each of the journal entries also includes a time stamp and/or a result of writing the data.

Continuous data backup

Accessing data file objects includes providing a file system interface on a client, where the file system interface allows an application running on the client to make file system calls to access the data file objects. A Web Services interface may also be provided on the client, where the Web Services interface allows an application to access file objects using the Web Services at the same time that file objects are being accessed through the file system interface. The Web Services interface may be a SOAP interface and/or a REST interface. Accessing data file objects may also include providing a direct file object interface on the client, where the direct file object interface allows an application to directly access file objects at the same time that file objects are being accessed using the Web Services interface and using the file system interface.

Simultaneously accessing file objects through web services and file services
