The power of the RIM and the power of standards

The resource inventory management (RIM) is a resource intensive task which is a part of the daily operations of the NRENs. Despite of the importance of the RIM there is no consensus among the NRENs about the scope of the activities which should be carried out are under the umbrella of the RIM. The TF-NOC survey indicates that the 39 answering NRENs are using 15 different software solutions for the RIM. The functionality is also distributed on large scale: it is not easy to find commonalities between MS Visio, MS Excel and Pinger. It is also interesting that MS Excel is the most popular tool (11/35). Some of the NRENs have realized the need for a more sophisticated solution and they have developed their own resource inventory management solutions (9/35). These solutions have been evolved based on the everyday needs, the question is how future proof are they? The Internet of the things (IoT), intelligent network (IN) and other coming paradigms require a holistic view from the network provider. The RIM is a part of this holistic picture. Under the umbrella of the GN3 project several IN network services have already been deployed among the participating NRENs (e.g.: Bandwidth on Demand, Autobahn, etc). Even in this small scale experiment it turns out that excel based offline resource inventory management is resource intensive. The integration of the home grown functionalities is not trivial as there is no common understanding of the scope of RIM. The total vertical software ecosystem applied by the NRENs show similarity both in the variety and in the applied domains. These solutions are in most case acting as islands without IT level integration. It is clear that the integration/standardization should be started with the beginning of the value chain. In our case this is the RIM. This paper and presentation will describe the results achieved in the field of OpenRIM development, deployment and testing. The results of this work are useful not only to GN3 as a project, but also to the wider community and especially NRENs. RIM will offer several benefits to support the reliable, effective and manageable networks: Component reuse: RIM and Network Visualization components can be used for service operations of different services Faster and easier integration and better compatibility of the existing and new OSS components with off the shelf tools or network/element management systems Automatic discovery of the network and the equipment
