Project Description

A fat-tree initializer and simple group feature test code based on ryu controller

Usage

Compile the Java Source Files for default fat-tree routing

In order to run the default fat-tree routing, first need to compile the corresponding Java Source Files in src directory. Use ant source builder to compile the entire source, a target directory will be generated.

cd routing
ant
./modFlowTablesByOvs.sh add k

Note that to compile the Java Source, you need to install the ant first. And k here denotes the fat-tree's parameter k. As default you can use 4.

Initialize the fat-tree topology

./run.sh

Execute ryu applications

ryu-manager ryu_sample.py

View the flow entries in a switch

ovs-ofctl dump-flows [switch_name] -O OpenFlow13

The switch name has the format like s[pod]_[sw_idx]_1 such as s0_0_1
