ONAP Beijing Release Developer Forum

Analyses of network controller performance are often referred to by the acronym S3P, representing scale, stability, security, and performance. Creation of a suitable test environment is often complicated by lack of available resources, inaccurate emulation of network agents, and difficulty ensuring all of the microservices in your network will scale together. Recent work investigating the scale performance of OpenDaylight controlling OpenStack Neutron networks has uncovered many issues that then led to improvements in ODL performance at scale. With OpenDaylight as the leading network controller in projects such as ONAP and OpenStack understanding the performance of the network control plane is critical to enabling performance of these platforms at scale. This talk will describe some of the complexities of network controller performance analysis, the difficulties that arise during testing of a scaled-out software defined network, and some of the findings from our recent work that can simplify the creation of a scale test environment.
