How can emerging applications benefit from EaaS in open programmable infrastructures?

Providing experimentation facilities in urban-scale infrastructures such as Smart City testbeds is a priority - and a challenge. Real-time performance, security, resource allocation and network convergence are only few of the issues to be tackled in order to provide proper and flexible Experimentation as a Service (EaaS) facilities in city-scale infrastructures. Software Defined Networking (SDN) and Network Function Virtualisation (NFV) appear as important enablers for providing such largescale testbeds, while promoting them as completely open programmable infrastructures. In this paper, we take the position of emerging applications or services designers/programmers that have stringent network requirements and want to know how to benefit from EaaS provided by open programmable (city-scale) infrastructures. Our focus is to evaluate the impact of SDN and NFV systems running real-time applications with low end-to-end latency and high bandwidth requirements correlated.
