Single Snapshot Exploratory Approach For
Visualizing Very Large Network Technologies
2
Introduction

• The networks nowadays are growing rapidly. This
  explosive growth makes manual network analysis
  practically impossible. Hence keeping in view
  these problems we have developed a method of
  displaying the entire network in a single
  snapshot, So that the network administrator can
  have an overview of the network.

3
Motivation

• The network visualization on which we are working
  provides a single snapshot view of the network
  infrastructure. The display is re-adjustable and
  updates itself in accordance with the changes in
  network. Hence the network managers know that
  what went wrong and where.

Problems Faced

• Three problems are most commonly encountered for
  large topology networks
• Display Clutter
• Node Positioning
• Perceptual Tension

5
Proposed Solution

• The entire area of screen is divided into layers.
• Nodes are positioned within these layers.
• We use color codes to define the type of machine
  being displayed as a node.
• SVG is the preferred technology for the job.

6
SVG to Display Topology Discovery

• SVG is used due to a number of reasons as its
  features fulfill all our display requirements.
• Plain Text format
• Scalable
• Zoom able
• Searchable and Selectable Text
• Scripting and Animation
• Works With Java Technology
• Open Standard
• True XML

The Algorithm (at 800X600 Resolution)

• Area of layer n (16 X 12)
• No. of nodes in n (16 X 12 px) n (4) where n1,
  2, 3, 4,5 NL (nlayer number)
• Maximum number of nodes that can be displayed l
  1?lan 1 ?n (4) n1, 2, 3, 4, 5NL.
  (nlayer number)

Results

• Hence according to the above calculations the
  following results can be derived
• The inner most layer contains 4 nodes
• The outer most layers that is the 50th layer
  contains 200 nodes
• the maximum number of nodes that can be placed in
  50 layers is 1?lan

Conclusion

• In this paper, we have discussed a technique for
  network visualization with minimum possibility of
  a cluttered display. The challenge was to achieve
  a clear and comprehensive view of the network, so
  that the network managers of vast
  telecommunication networks can have idea of their
  network. It is practically almost impossible to
  manually examine such networks node by node.
• For this purpose the best choice was SVG.
  Graphics in SVG can be zoomed in for better
  viewing and there is negligible corrosion of the
  image. Further unlike raster images it does not
  produce stair case effect while printing images.
  One very major reason for using SVG was its
  compatibility with java. Being XML based SVG has
  vast compatibilities.
