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

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.
