Main Comopnents of Our Visualization System Recorded Log File

Overlay Weaver ClusterOverlay Weaver Cluster

Overlay Weaver is able to construct

both a network of real computers and

an emulated network of virtual nodes

on a single computer.

[ http://overlayweaver.sourceforge.net/ ]

You can switch visualization styles.

Since messages in step (3) are text protocols,

you can record them easily

You can use the log files recorded in advance

in place of Overlay Weaver cluster for convenience.

We already implemented

visualization styles for GFRT-Chord.

You can implement another visualization

styles from another viewpoint.

What Should Researchers Do to Demonstrate Research Results to the Public ?

The public does not know what is a good algorithm.

Researchers should emphasize their contribution.

Researchers must not be satisfied with

the visualization of their own algorithm.

Emphasizing

differences between

algorithms is an effective way.

It’s a beautiful visualization !(What is your contribution ???)

We visualized !

Your contribution is !

This is our contribution.

Do researchers have to implement

various systems ?

They may want to change

the point to be emphasized dynamically.

A point to be emphasized varies depending on the context.

We implemented selectable visualization styles.

Our implementation’s other features :

You can demonstrate on a single laptop.

The system does not need a list of all nodes in advance.

You can change visualization styles

seamlessly and dynamically.
