OpenStack Performance with OVS-DPDK for NFV and Connection Tracking, with Sugesh Chandran and Bhanuprakash Bodireddy from Intel

OVS Orbit

Sugesh Chandran is a network software engineer with Intel. His work is primarily focused on accelerated software switching solutions in user space running on Intel architecture. His contributions to Open vSwitch with DPDK include tunneling acceleration and enabling hardware acceleration. Before joining Intel, he has been involved in developing features for Cisco and Procurve switching products.

Bhanuprakash is a software engineer at Intel Corporation focusing on virtual switching solutions. Before joining Intel, he has been involved in building telecom solutions for Asian mobile operators and had significant contributions towards fast-path optimization in vEPC. He also worked on building reliable fronthaul solution at a startup that built vRAN using Ethernet fronthaul. He is also passionate about FOSS and has actively contributed to FreeBSD MIPS and OVS.

This episode is a talk that Sugesh and Bhanuprakash gave at OpenStack Boston during the Open vSwitch Open Source Day on May 10, with the following abstract:

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 wal kthrough their 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.

Slides for this talk are available in PDF format. Some parts of the talk will be easier to follow while looking at the slides.

Bhanuprakash previously presented two talks related to OVS-DPDK at Open vSwitch 2016 Fall Conference.
