Intro

Click is a modular router library developed at UCLA, allowing Click-definied router networks to be ‘attached’ to an ns-3- nodes layer 3 functionality. It has very little relevance to my own research, but was interesting to play with.

In a nutshell, Click is an extention to the linux kernel that provides a highly performant and configurable routing architecture.

Requirements

• Already installed ns-3

• git

• ~/src directory

Get ‘er dun

cd ~/src; git clone git://read.cs.ucla.edu/git/click ; cd click sudo ./configure --enable-nsclick --enable-userlevel; sudo make; sudo make install

Sudo ./configure is required to grant access to some root-only areas of the kernel tree

This should install everything under /usr/local/include/click, but leaves the shared library files in the src dir (This tripped me up a bit…)

cd ~/src/<ns3-working-dir>/

./waf distclean

./waf --enable-nsclick=~/src/click --enable-examples $(plus whatever additional clauses you use, I like --visualize --enable-mpi --enable-tests --enable-sudo)

./waf --run nsclick-simple-lan

Jobs a good one
