D-4.5 Evaluation of the in-network management approach

The deliverable D-4.5 Evaluation of the in-network management approach is available for review and comment.
Work Package 4 (WP4) of 4WARD has worked towards the definition of novel management instruments to operate the future Internet. In-Network Management, (INM), utilizes decentralization, self- organization and autonomy as its basic enabling concepts. The idea is that, contrary to the legacy centralized approach, the management tasks are embedded in the network. The managed system now executes management functions on its own. The INM concepts and its design are detailed in 4WARD WP4 deliverables D4.2 In-Network Management Concept ] and D-4.3 In-network management design].
Deliverable D4.1 described scenarios and use cases for the Future Internet, and for each scenario, derived requirements to enable it. This deliverable compiles a comprehensive list of requirements from all the scenarios, and uses them as a basis for evaluating the INM design concepts developed by all WP4 tasks.
The evaluation process follows a WP4-adapted V-model, in which the INM implementation is checked against its testing results in a top-down approach, from the full system down to each of its components. This methodology facilitates an evaluation without the need for a comprehensive implementation of all NM functionality, a valuable feature for this clean-slate conceptual project. The evaluation effort is split into three separated topics that match the structure of the WP4 activities: framework, algorithms and a demonstrator. Depending on the extent of the implementation, different evaluation instruments are used.
The analysis utilizes two agreed templates, one for the framework and one for the algorithms. The framework is evaluated for scalability, robustness, reduced integration effort, and reduction of complexity. Each INM algorithm from tasks 4.3 and 4.4 is evaluated with the algorithm template.
Special attention was given for the evaluation of cross WP activities: INM for NewAPC (cross WP2/4), INM for VNET (cross WP3/4), INM for GPs (cross WP4/5), and INM for NetInf (cross WP4/6). The business aspects of INM (includes cross WP1/4) were also studied.
The evaluation analysis demonstrates that every requirement identified in Deliverable D4.1 was addressed by some algorithms in D4.2 ] and D-4.3 ]. The degree of coverage of each requirement varies, and explanations are given for those that are lightly addressed. Compared with legacy management systems, INM design is shown to be scalable and robust. Moreover it facilitates reduction of integration effort and reduction of complexity. Most importantly, INM is beneficial for NewAPC, VNets, GPs and NetInf, and it demonstrates business incentives that are realized with potentially reduced OPEX and increased EBITDA values.
In summary, the evaluation analysis of the simulation results shows that the INM design is beneficial for the Future Internet. The next step is to test the feasibility of INM concepts in real experimental networks.
