Experimenting latency-aware and reliable service chaining in Next Generation Internet testbed facility

In this paper we report experimental validation of an orchestration system for geographically distributed Edge/NFV clouds, supporting end-to-end latency-aware and reliable network service chaining. The orchestration system includes advanced features such as dynamic virtual function selection and intentbased traffic steering control across heterogeneous SDN infrastructures. The experiment run under the 1st Open Call of the Fed4FIRE+ EU H2020 Project and took advantage of bare metal servers provided by the Fed4FIRE platform to set up a distributed SDN/NFV deployment. We provide details on how this orchestration system has been deployed on top of Fed4FIRE facility and present experimental results assessing the effectiveness of the proposed orchestration approach
