Measure latency(delay), jitter, packet loss ratio of all network links, in ONOS

ONOS_Link_Quality_Measurement

An active method to measure link quality: latency(delay) / jitter / packet loss ratio. Performed by ONOS controller.

If you like this project, please click Star at the top-right corner, thanks for your support :)

Discuss on ONOS mailing list: Is there any app/module/manager that can detect the quality of network links?

.

Update Note

2020.10.18 Support link delay measurement, based on ONOS 2.5.0-SNAPSHOT version, backed by Apache Karaf 4.2.9 & JDK 11.

.

Demo

sudo tc qdisc add dev s1-eth2 root netem delay 100ms
sudo tc qdisc add dev s2-eth3 root netem delay 300ms

.

Latest Instruction to Compile

1. Embed me with ONOS codebase
2. Modify the $ONOS_ROOT/tools/build/bazel/modules.bzl file, refer to modules.bzl__available_example file
3. Build whole ONOS by bazel. (You can use my utility script for ONOS: https://github.com/MaoJianwei/SDN_Scripts/blob/master/ONOS/autoONOS_Bazel.sh)

Out-of-date: ONOS does not support to be built and imported to IDE(Intellij IDEA) by Maven(pom.xml) anymore, we should use Bazel(BUILD).

.

Backward Compatibility

You can find all milestone versions at Release page.

onos_link_quality_measurement's Issues

Packet deserialization problem和NullPointerException

我运行您的代码控制器报了以下错误：

其中NullPointerException是出现在下面这个位置：

这是因为context.inPacket()得到的InboundPacket类型不是Ethernet，所以得到了一个null！
那么这些错误应该怎么修改呢？
