8. Scalable and Cost Efficient Algorithms for Virtual CDN Migration

Abstract

Virtual Content Delivery Network (vCDN) migration is necessary to optimize the use of resources and improve the performance of the overall SDN/NFV-based CDN function in terms of network operator cost reduction and high streaming quality. It requires intelligent and enticed joint SDN/NFV migration algorithms due to the evident huge amount of traffic to be delivered to end customers of the network. In this paper, two approaches for finding the optimal and near optimal path placement(s) and vCDN migration(s) are proposed (OPAC and HPAC). Moreover, several scenarios are considered to quantify the OPAC and HPAC behaviors and to compare their efficiency in terms of migration cost, migration time, vCDN replication number, and other cost factors. Then, they are implemented and evaluated under different network scales. Finally, the proposed algorithms are integrated in an SDN/NFV framework.

23. Prognostic-Based Maintenance Optimization For Complex Systems

Abstract

This paper is concerned with prognostic information for maintenance and production optimization in complex systems. In each stage of such a system, we allow redundant components used as backup to ensure system's availability. Remaining Useful Life (RUL, the so-called prognostic information) of components is used to evaluate each component's redundancy. We address RUL-based maintenance and production optimization to guarantee the availability and productivity of the system such that client demands can be satisfied in a given planning horizon. We propose a mixed-integer linear programming model to minimize the total cost. Experimental results on test instances show the efficiency of the proposed approach to attain optimal solutions.

Abstract

International audience; Cloud-Radio Access Network is a promising mobile network architecture that centralizes the computing resources in the Baseband Unit pool which adds more flexibility and increases network performance. However, as computing resources are shared among the Radio Remote Heads (RRH) connected to the Baseband Unit pool, efficient scheduling algorithms should be explored to meet the deadlines requirements of RRHs' subframes and to increase the network throughput. In this paper, we propose optimal scheduling algorithms for computing resources along with three heuristics. We test the different algorithms as a function of three metrics. The evaluation is performed under a real traffic model and the results highlight the importance of choosing the appropriate scheduling algorithm to increase network performance.

32. Dynamic and adaptive grouping maintenance strategies: New scalable optimization algorithms

Author

Hanini, Maria, Khebbache, Selma, Bouillaut, Laurent, and Hadji, Makhlouf

Abstract

This paper focuses on new efficient and adaptive optimization algorithms to cope with the maintenance grouping problem for series, parallel, and complex systems. We propose a Particle Swarm Optimization approach to cope with small and medium problem sizes, and that will be used to benchmark existing heuristic solutions such as Genetic Algorithms. To address scalability and adaptability issues, we propose a new dynamic optimization algorithm based on a clustering technique. This clustering-based solution is formulated using an Integer Linear Programing approach to guarantee the convergence to global optimal solutions of the considered problem. We show the performance of the proposed approaches with a clear advantage to the clustering-based algorithm that we recommend for large industrial systems.
