Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for performing incremental software installations. The system identifies a set of files associated with one or more software programs. Each file can be a component of a software program, or any file accessed by the software program or system when the software program is executed. The system receives a list of files associated with a software version that is not installed on the system. The system determines the differences between the set of files and the list of files, and receives a missing file from the list of files based on the differences. Finally, the system builds the software version on the system using the set of files and the missing file. In building the software version, the system does not assume a linear progression of updates and is able to reuse existing files to create nonlinear variations of software.

Abstract: An access control system for a network manager system provided with a plurality of building blocks (BBs), each specialized for executing a plurality of functions on a plurality of resources of the network, and with a graphical user interface (GUI). Each BB comprises a database for storing access control data pertinent to said component including all resources accessible to the BB, all functions executable by the BB and all users that have the right to use the BB, according to privileges allocated to each user. The BB also comprises an access control library for writing and reading the access control data to and from the database for execution of a network operation according to the respective privileges. The access control system further comprises an access control user interface connected to the access control library of each BB, for viewing and editing the access control data on the GUI.

Abstract: The user interface is divided into client-server portions, based on the multilevel model-view-controller (MMVC) architecture. The MMVC architecture results in a high performance user interface that addresses the problem of how to divide functionality, and introduces performance issues in a distributed or three-tier architecture. This division of concerns results in a dramatic reduction in the size of the component which runs on the user's terminal, resulting in lighter weight client interfaces, that are flexible and powerful and does not require to have a high bandwidth connection to the server. Thus, the user's terminal may be a low-end personal computer with a dial-up access to the Internet service provider. This layered structure may be built over an existing network manager provided with a graphical user interface.
