OPNFV VIM integrates control and management components from upstream projects such as openstack, ONOS, ODL, etc. While huge success has been achieved in OPNFV for integration, automated build and deployment, the performance of VIM for controlling and managing virtual network has received little attention. This presentation is to address the VIM performance related to the network part of the infrastructure. Based on a Telco use case, we define performance metrics for SDN controller, northbound communication channels, and network provisioning. ONOSFW and OpenStack are two components for VIM. Test data is collected and analyzed for performance evaluation and suggestions for future improvements. China Unicom, ON.LAB and Huawei jointly define the use case and methodology, do analysis, and produce results.
