Extensible, Transactional Architecture for IP Connectivity Management

This paper presents an extensible, transaction oriented Element Manager System (EMS) architecture for IP connectivity management. The key aspects of the proposal are the extensibility, derived from the adoption of an object oriented, policy-based approach, and the transactional feature, which ensures both EMS repository data information and network configuration integrity. This means that an intended Connectivity Service is configured end to end in one atomic operation, as seen by the Network Management System (NMS), or not configured at all, if any of the steps of the ongoing operation fails. Management data and policies are stored as persistent objects in a common repository. This provides not only an inventory of the managed elements, but also a policy-driven application environment. The paper briefly describes the Information Model, the solution adopted, and presents a proof of concept implementation.
