Our decade is marked by an increase in the use of mobile networks for industrial and administration actors as well as for the general public thanks to their evolution. The introduction of the 5th generation of mobile networks, 5G, brings a diversity of use cases for mobile networks and a growing number of demands with very heterogeneous needs...

Network Functions Virtualization (NFV) enables the complete decoupling of network functions from proprietary appliances and runs them as software applications on general–purpose servers. NFV allows network operators to dynamically deploy Virtual Network Functions (VNFs).Software Defined Networking (SDN) introduces a logically centralized...

Modern 5G networks promise more bandwidth, less delay and more flexibility for an ever increasing number of users and applications, with Software Defined Networking, Network Function Virtualization and Network Slicing as key enablers. Within that context, efficiently provisioning the network and cloud resources of a wide variety of applications...

Ce travail vise à montrer l'utilité de reconfigurer des chaînes de fonctions de services (SFC) dans le but d'améliorer le coût opérationnel du réseau. Nous proposons un modèle d'optimisation basé sur le mécanism emake-before-break, dans lequel l'ancien chemin n'est détruit que quand le nouveau chemin est complètement opérationnel, ceci afin de...

Software Defined Networking (SDN) and NetworkFunction Virtualization (NFV) are complementary and corecomponents of modernized networks. In this paper, we considerthe problem of reconfiguring Service Function Chains (SFC)with the goal of bringing the network from a sub-optimal toan optimal operational state. ...

The emerging 5G induces a great diversity of use cases, a multiplication of the number of connections, an increase in throughput as well as stronger constraints in terms of quality of service such as low latency and isolation of requests. To support these new constraints, Network Function Virtualization (NFV) and Software Defined Network (SDN)...
