We are building an intelligent switch which can satisfy a particular bandwidth/delay requirement. It classifies the packet according to the protocol of the packet.
What we'll accomplish is
- TCP packets will be send on a bandwidth. Say 500 kb/s
- UDP packets will be send on a different bandwidth. 1000 kb/s
- Clone this repository
cdinto this repository- Create a new virtualenv of python2 in this repository
virtualenv --python=/usr/bin/python2 env
- Activate this environment
source env/bin/activate
- Install ryu using pip
pip install ryu
- Clone RYU repository
git clone https://github.com/osrg/ryu.git
- Install ryu
cd ryu
pip install .
- Come out from ryu directory
cd ..
- Start mininet topology
sudo mn -c
./start_mininet.sh
- Setup switch, open xterm window in s1
xterm s1
- In switch's xterm do,
./setup_switch.sh
- Open two xterm windows of c0
xterm c0 c0
- In one xterm window, Do the following
source env/bin/activate
./start_ryu_manager.sh
- In the other xterm window, dot the following
./set_ovsdb_addr.sh
./setup_q.sh
./add_qos_rules.sh
- Now open 2 windows of h1 and h2 each.
xterm h1 h1 h2 h2
- In first window of h1, do the following
./create_tcp_server.sh
- In second window of h1, do
./create_udp_server.sh
- In first window of h2, do
./send_traffic_tcp.sh
- In second window of h2, do
./send_traffic_udp.sh
- Now examine the bandwidth in h1 xterm windows and see the difference for tcp and udp.
Note: This is a modified version of RYU Book QoS Example 1 (12.2). The only difference is there the classification is based on destination port and here it is based on protocol of the packet.
