This talk analyzes the performance of OvS-DPDK in two situations relevant to OpenStack.
First, the speakers will analyze the performance of the OvS-DPDK connection tracker, which plays a critical role in protecting tenants and application workloads from network-based attacks. They will demo and walkthrough theirs findings with different test topologies that includes multiple VMs, bridges with thousands of connections. They will showcase Vtune results for specific bottlenecks and discuss mitigation strategies.
Second, the speakers will analyze the performance of OvS-DPDK for Network Function Virtualization (NFV). This part of the talk will describe a few real world deployment with OvS-DPDK and walk through various scenarios. This includes latency details, scalability, NUMA node aware allocation, Classifier bottleneck, Noisy neighbor and hardware acceleration features.
