A small test program that reproduces reordering of FlowRuleEvents in ONOS

Overview

This repository provides a small test program that reproduces FlowRuleEvent reordering reported in ONOS-5093.

How to build

Just enter the following command under the project directory.

mvn clean install

How to use

1. Start ONOS on your machine with

ok clean

2. Start Mininet

sudo mn --topo linear,10 --controller=remote,ip=<IP address of ONOS>

3. Run the application There are multiple ways to deploy and run an ONOS application (more info). The recommended way here is using ONOS Web UI. Open "Application" in the menu appearing when clicking the upper left corner button. Click the "+" button to install a new application. The application file is target/reorder-test-1.0-SNAPSHOT.oar.

4. Check the log You can check the log on your machine with

log:tail

or

log:display

You could see warning-level log outputs. The results may differ every execution because multi-threading causes the issue.
