Methods and systems for autonomously managing computer networks are provided. In a preferred embodiment of the invention, management functions are organized in a novel two-layer peer-to-peer (P2P) architecture. The bottom layer organizes management information in a unified object-relationship model, that is instantiated in a distributed transactional object repository. The top layer unifies the traditional roles of managers and elements into a single autonomic management peering layer. Autonomic elements use the repository as a primary management repository, and effect autonomic behavior in terms of transactions over the shared model state. A novel autonomic policy model and language, Object Spreadsheet Language (OSL), in the form of acyclic spreadsheet change propagation rules, and declarative constraints is also provided.

A circuit arrangement and method make state changes to shared state data in a highly multithreaded environment by propagating or streaming the changes to multiple parallel hardware threads of execution in the multithreaded environment using an on-chip communications network and without attempting to access any copy of the shared state data in a shared memory to which the parallel threads of execution are also coupled. Through the use of an on-chip communications network, changes to the shared state data may be communicated quickly and efficiently to multiple threads of execution, enabling those threads to locally update their local copies of the shared state. Furthermore, by avoiding attempts to access a shared memory, the interface to the shared memory is not overloaded with concurrent access attempts, thus preserving memory bandwidth for other activities and reducing memory latency. Particularly for larger shared states, propagating the changes, rather than an entire shared state, further improves performance by reducing the amount of data communicated over the on-chip communications network.

Certain example embodiments relate to selective change propagation techniques for supporting partial roundtrips in model-to-model transformations. In certain example embodiments, enablement checking is performed to determine whether a propagation operation can be performed for an object. If the object passes enablement checking, the propagation is executed by, for example, creating the object(s) in a business-oriented (e.g., EPC) model; updating relevant internal attributes of technical (e.g., BPMN) objects that allow for the successful merge; optionally correcting user-introduced errors in the technical model; and properly connecting the pulled-up objects with their surroundings. The connecting is performed so that the objects advantageously appear as if the current business-oriented model was used for the merge. According to certain example embodiments, the connecting may be deterministic, e.g., such that the result will be the same regardless of order or sequence in which the propagations are made.

A method and manager node is provided for verifying status information of Managed Objects (MOs) of a management system before propagating an update to a managed network. Subsequent to an attribute change of a given MO in the manager, the manager detects other MOs related to the updated MO, such as neighbour radio cells of a given radio cell. The manager obtains status information relative to each related MO, such as synchronization information, connection information or coupling information. If the status information is adequate for pursuing the update, the manager propagates the update to the managed network. Otherwise, the manager issues a warning to the system administrator, and only propagates the change to the managed network when confirmed by the systems administrator.
