The Script way
Other ways view the full article at http://askubuntu.com/questions/56104/how-can-i-install-sun-oracles-proprietary-java-jdk-6-7-8-or-jre
Before using this make sure that this script is in the same directory as the
.tar.gzfile extension that you downloaded and there are no files that start with jdk-7 in the same folder. If there are, please move them out of the folder temporarily. Remember to make the script executable (
chmod +x <script's file>).
If you want to install the plugin for Firefox then add this to the end of the script:
#!/bin/sh tar -xvf jdk1.8* #Change by the you downloaded from oracle sudo mkdir /usr/lib/jvm sudo mv ./jdk1.7* /usr/lib/jvm/jdk1.7.0 sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdkx.y.z/bin/java" 1 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk
x.y.z/bin/javac" 1 sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk
x.y.z/bin/javaws" 1 sudo chmod a+x /usr/bin/java sudo chmod a+x /usr/bin/javac sudo chmod a+x /usr/bin/javaws
mkdir ~/.mozilla/plugins ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/amd64/libnpjp2.so ~/.mozilla/plugins/ sudo /etc/init.d/apparmor restart

Traffic shaping on Linux system used to require knowledge of lot of things like iptables, qdiscs & networking protocols. Things have changed and now there are couple of tools which handle all of this complexity without requiring much knowledge. And one of them is wondershaper.
First install wondershaper by issuing following command. sudo apt-get -y install wondershaper
Use following command template to make it work right away.
sudo wondershaper <interface name> <down speed> <up speed>
Where interface name is your network interface name like eth0 or eth1 or wifi0 and down speed , up speed are self explanatory and specified in kilo bits per second.
So sample command will look like
sudo wondershaper eth0 512 512
To disable wondershaper from controlling particular interface use following command. sudo wondershaper clear <interface name>
To make these changes permanent add following lines to /etc/network/interfaces under relevant interface section. up /sbin/wondershaper <interface name> <downspeed> <upspeed> down /sbin/wondershaper clear <interface name>
Thats it, From now on all sensitive traffic like your voip, HTTP, SSH will get prioritied while heavy traffic like bit torrent will not be prioritized. This is not a perfect tool for the job but simple enough to be used by newbies.
