Green Virtual Networks for Timely Hybrid Synchrony Distributed Systems
Rasha Hasan, Odorico Machado Mendizabal, Fernando Luís Dotti · 2024
Timely hybrid synchrony distributed systems are the kind of systems that do have timely-bounded synchrony constraints for both node processing execution and link message delivery. This hybrid synchrony feature proved to be useful for solving certain problems in the literature, for example, the consensus problem. A physical hybrid substrate for these systems is not a solution that goes in accordance with sus-tainability standards for several reasons basically in terms of energy use, resource consolidation, E-resources waste, and data centers' environmental effect. In our work we propose virtual networks for data centers that host timely hybrid synchronous distributed systems, and this solution would result in minimizing the environmental impact, while still providing reliable and available solutions. This work is a continuity of our previous one where we proposed a resources allocation mathematical model. The contribution of our current work is threefold, firstly we motivate the use of hybrid synchrony virtual networks by clarifying sustainable aspects, along while listing real-life applications that would benefit from it, secondly, we detail the phases of the resources allocation process, and thirdy, we make further experiments that our previous ones with the objective of evaluating the performance of the micro-embedding phase. Results show that the proposed model can handle the embedding problem in an efficient manner within an acceptable solving time.
