This document contains a description of the network infrastructure belonging to Oslo University College. It takes a large a complicated network and breaks it up into smaller and more manageable parts for a closer examination. Methods for abstracting and presenting fiber infrastructure are introduced. So are methods for drawing equipment diagrams and graphically overview maps for conveying large amounts of data in the easiest way possible. How to best present information and draw diagrams are a large part of this assignment. But the project also has a main goal to document all the equipment used throughout the network. This will be helpful for the network administrator since it has never been done before.
