Abstract:
Building an end-to-end view of the network in multi-service networks is a very important building block in creating a correct view of the capabilities of the network and is therefore crucial for service deployment, activation and management. At the same time, it is a very difficult task to achieve. Current inventory solutions are static in nature, which introduces problems of data consistency between the managed domain and the view at the management node. An end-to-end view of the network is also hard to achieve because no common data model is in use today, and inventory information between different domains is very hard, if not impossible, to obtain using the current solutions. This paper discusses the challenges of building an end-to-end view of the network topology, discusses existing solutions, and proposes Stratus, a flexible unified SOA-based architecture that has been implemented and deployed in our lab. Stratus is based on the MTOSI recommendations for inventory retrieval, an
d comes with a mechanism for data mapping from domain managers for Public Ethernet and Core Wireline Access Networks to the MTOSI model. It also provides dynamic discovery of the different domains in the network, automatic end-to-end topology creation, and notification systems for automatic updates of the topology based on updates in the network. The experiments show that the proposed solution is technically feasible and compatible with existing inventory solutions.
