OpenDaylight (ODL) Performance Report

OpenDaylight Base Edition – Hydrogen release benchmarked using Veryx PktBlaster SDN Controller

We conducted some performance tests in our lab for OpenDaylight Base Edition – Hydrogen release SDN controller, running on standard server platform, using Veryx PktBlaster SDN. The server platforms had dual Intel Xeon processors with 16GB of RAM.
The objective of this performance test is to assess the controller’s Flow Setup rate (a.k.a. Throughput) and Flow Setup time (a.k.a. Latency) for constant and varying network loads. The test had been configured to use OpenFlow 1.3 version, and TCP connection setup.

The first test was conducted with a constant switch load of 128 switches. We observed that the controller’s average Flow Setup rate was 3315 flows per second and the average time to setup a flow on a switch was 618 milliseconds. Please refer Reports 1 and 2 for more details.

The second test was conducted with 64 switches, and then stepped up to increase the number of switches in every iteration by 25%- essentially, ranging from 64 to 256 switches.

We observed that the controller’s maximum Flow Setup rate was 10653 flows per second for a switch load of 64 switches and the minimum flow setup time was 401 milliseconds for switch load 128 switches. Please refer Reports 3 and 4 for more details.

We conclude that the OpenDaylight base edition hydrogen release gives lower flow setup rate and higher flow setup delay. While it may not be ideal for a network infrastructure which is highly dynamic, it provides a great starting point for those who wish to do a proof of concept (POC) before transitioning to SDN based network.

Veryx is working on measuring performance of other public domain SDN controllers (OpenFlow and non-OpenFlow) and will be publishing them in Veryx’s blog periodically. Please stay tuned.
