What is DIMES?

www.netdimes.org

Distributed Internet MEasurements & Simulations

Background

DIMES lab is located in Tel Aviv University. The research is performed through Local

Agents on computers throughout the world. DIMES lab is producing a weekly internet

visual topology maps that can help examine how the Internet topology changes over time.

Previous Project

The topology maps are being viewed with a tool called: The DIMES Visualizer

Requiring a manual downloading of a zip file & local execution.

The connection to the DIMES DB is very poor.

A very slow and heavy tool!

On the fly DIMES map generator: Enabling view of all kind of information about a week

in a network life. Enabling control of the 3D graph such as zoom-in,

zoom-out, rotate 360, color display and more.

A webby research tool, no data download. Produce 3D graphs out of raw data. Improve current work environment look, feel

and speed.

Creating Translation Files

DIMES projects gathers weekly information of ASes, edges.

Our Location Generator program extracts the data into ready to use files.

The files are then used as input to generate 3-D graphs using Tomer Tankel’s algorithms.

RMI Connection To DB

The connection between the Dimes Lab DB and our application is done by RMI connection.

Distribution Algorithm

The algorithm uses the Dijkstra algorithm to distribute the data on a 3-D graph.

The efficiency of Dijkstra algorithm is The most connected AS is placed in the

center of the graph. Its neighbors surround it in a recursive

manner in 3 dimensions.

3D Display Interface and Filter

The application is displaying the data using the Java3D pack.

Our rich interface enables the user to alter the data appearance and view: Data filtering: user may concentrate on specific

AS and view the routes embarking from it. Color palette Objects appearance Zoom in and out
