VSPERF – Test and Performance Subgroup Demo 26/08/2015 Maryam Tahhan

VSPERF A Python based test framework for characterizing the performance of virtual switches. As of today, capable of conducting: – RFC2544 throughput tests (P2P and PVP) | RFC2544 throughput scalability tests. – RFC2544 back to back tests (P2P and PVP) –A simple performance test (P2P) –CPU/Memory load tests. On OVS with DPDK as well as Vanilla OVS.

3 Deployment scenarios supported to date P2PPVP

4 VSPERF Directories conf: contains the main configuration for testcases, vSwitches, traffic generators and VNFs core: contains the controllers for vSwitches, traffic generators and VNFs. These controllers look after the configuration and launching of deployment scenarios for vSwitches, traffic generators and VNFs. Implementation details of vSwitches, traffic generators and VNFs are abstracted from the controllers. src: looks after cloning and building the libraries/utitlites we depend on including OVS, DPDK and QEMU (v2.2.1 for CentOS 7). testcases: contains the base implementation of a testcase. tools: contains the implementation of packet generators, collectors and load generators. vnfs: contain the implementation that allow us to launch a VM with a particular hypervisor vswitches: contains the implementation of virtual switches.
