OpenStack Liberty Design Summit

Now that Neutron has been established as the OpenStack Networking component and with the ongoing efforts in the Neutron community to make it a more stable, more efficient, and more scalable component, it is time to provide a broad analysis of the performance and scalability of Neutron. In this talk we discuss a methodology for benchmarking the network performance with Neutron. To this end, we consider both the control plane and the data plane network performance. We utilize a large scale setup and investigate the scalability boundaries of Neutron while comparing the results obtained from the Neutron reference implementations and open source controllers. We furthermore, focus of packet level performance of these implementations and identify the bottlenecks.

We aim to establish an easy to use and reproducible methodology for reporting networking performance in OpenStack cloud environments with Neutron.
