Objective 7: Optimal placement of Virtual Network Functions on top of SDN networks

Motivation

The optimal services deployment from NFV to SDN networks require suitable architectures, regarding the current specification of NFV, the performance of the SDN controllers, and the optimization restrictions considered. In the same way, the specification of the interface between the SDN and the NFV is open, so work is required on its definition. Nevertheless, it is a huge challenge to define a generic SDN-NFV interface, since the specific nature of the VNF (Virtual Network Function) makes the interface specification complex, and thus, work is required on this issue. Algorithms will be studied, based on VNE (Virtual Network Embedding) strategies, and using simulation tools like the ALEVIN software, or the R-Software.

The aim is to define a generic SDN-NFV interface, since the specific nature of the VNF (Virtual Network Function) makes the interface specification complex. Algorithms will be studied, based on VNE (Virtual Network Embedding) strategies, and using simulation tools like the ALEVIN software, or the R-Software. Suitable architectures will be investigated in order to deployed NFV on top of SDN networks, regarding services in real networks, wired and wireless, including sensor networks. In this objective, algorithms will be investigated in order to deploy optimally the decisions taken at the NFV level, on the SDN network.
