The UniverSelf project is proud to announce the release of the case study- Part 1: 

Use Case #2 - Networks' Stability and Performance

The case study can be accessed under the Dissemination/White papers section, or directly at the following link: http://www.univerself-project.eu/white-papers


Today networks are becoming more and more ubiquitous and dynamic. In the near future they will be able to hook together a sheer number of heterogeneous (processing, communication and storage) real/virtual resources. One of the major challenges of will be managing such large amount of resources in a cost effective and timely way in order to meet technical and business requirements, which, in turn, may change dynamically. Introducing self-organization capabilities in network control and management is seen as a potential answer to face these challenges whilst ensuring network adaptability to changing conditions. In essence, these self-organisation capabilities can be practically achieved through the exploitations of “constrained optimizations” (CO) solvers (i.e. through protocols, control loops, algorithms…spread across network layers). These solvers have to be properly orchestrated to avoid instabilities due to unwanted couplings or interactions. Actually, it should be noted that the potential occurrence of network instability might have primary effects, such as jeopardizing dramatically the performance and compromising an optimized use of resources. Ensuring stability of a strategic asset like a network of ICT resources is of paramount importance for the information society. The main goals of the case study on Networks Stability and Performance are to report on the development and demonstration of methodologies and practical approaches to detect and control the potential occurrence of instabilities in diverse network contexts. This document presents a brief description of the use case, its methods, concepts and expected innovation. The specific functional, non-functional requirements and the associated problems were presented in the deliverable D4.1 [20]. The prioritization of the problems and functional requirements were presented in deliverable D4.2 [21].
