A controller is used to provide a sharable, programmable and composable infrastructure. The controller includes a user manager to take input of user application programming interface calls that correspond to actions accepted from users. A physical manager fulfills requests from the user manager by manipulating distributed physical resources and logical devices in a network controlled by the controller. A configuration effector implements configuration changes to the physical resources and logical devices. A device monitor determines a status of the physical resources and logical devices, propagates the status to the physical manager for detecting a failure of the physical resources and logical devices in real-time, and mitigates the failure.

In one embodiment, the disclosed technology involves modeling network elements, such as router configurations and link information, as well as any generic network status, as data in a relational database. Various network data, such as router states and link states are abstracted into tables in the relational database. Network management operations may then be represented as a series of transactional database queries and insertions. As a result, the database automatically propagates, to the appropriate network elements, state changes that are written to database tables, thereby implementing various network operations. Tables in the database can be constructed at various levels of abstraction, as required to satisfy network operational demands. Programmability is provided by a declarative language composed of a series of database queries and insertions.

A system includes a memory storing a set of instructions executable by a processor. The set of instructions is operable to receive a process for accomplishing a network management task, the process including a plurality of events including configuration changing events and condition checking events; receive parameters related to the task; include the parameters in the process; and execute the process.

The disclosed technology involves the use of relational databases in conjunction with declarative language and network-wide, database abstractions to manage and operate networks. The data model creates a logically centralized database abstraction and access point for managing data relevant to network management. Exemplary managed data includes router configurations, network status and provisioning data. This information resides in a single database system which is tightly integrated with the operational network. Transactional write operations are used to change network configurations, and enforce constraints to detect and prevent policy violations during operation. In accordance with one aspect of the disclosed technology, a network operation is implemented by means of a series of database commands—read and/or write—from and to database view tables.

Methods and apparatus to configure virtual private mobile networks for security are disclosed. A disclosed example method includes identifying, in a wireless network, a communication from a user equipment that matches a security event profile, transmitting, from the wireless network, an instruction to enable the user equipment to be communicatively coupled to a virtual private mobile network, the virtual private mobile network being provisioned for security within the wireless network, and enabling the user equipment to transmit a second communication through the virtual private mobile network securely isolated from other portions of the wireless network.
