How To Setup OpenFlow Soft Switch on Ubuntu 12.04 LTS
I installed from the standard GIT library. The process is given here.
Download & Install
sudo apt-get install git-core automake m4 pkg-config libtool
git clone git://openflow.org/openflow.git
cd openflow
./boot.sh
Configure
You better disable Network Manger in Ubuntu, otherwise it tries to configure/re-configure the ethernet interfaces, which might interfere with the OpenFlow standards.
1.How to disable Network Manage:
run sudo gedit /etc/NetworkManager/NetworkManager.conf
change "managed=true" under [ifupdown]
2.Restart the networking
run sudo service network restart
3.Make the switch ethernet interfaces down [no IP addresses are assigned to the switch ports]
run sudo ifconfig <interface_name> down
Run
1. Running OpenFlow data path
ofdatapath punix:/var/run/dp0.sock -i eth1,eth4 --local-port=tap:tap1
2. Running OpenFlow protocol to connect to the controller
ofprotocol unix:/var/run/dp0.sock tcp:<controller_IP>

Gstreamer
gstreamer works in a pipeline, where you have to connect different component for multimedia processing.
gstreamer-java is available here with examples.
A comprehensive example is given here (written by me)

How to setup IP ToS bit
in C++
int tos = 0x10; // Type of Service Field
setsockopt(sockfd, IPPROTO_IP, IP_TOS, &tos, sizeof(tos));
Java
DatagramSocket socket = new DatagramSocket();clientSocket.bind(new InetSocketAddress(port));
socket .setTrafficClass(0x20);
<Code runs without any exception; however IP ToS bit does not change! >
