Introduction

Currently, topology Visualization only plot the Layer 3 topology from IEPM Traceroute data.  This page describes the design and implementation detail of topology visualization.

 Design

  1. Visualize topology of any network supported by PerfSONAR framework in a well specified format.
  2. Look up for the topology information, if it is not available locally.
  3. Provide a wide range of  analysis using  bar chars, histograms, pie charts of vairious  network parameters supported and provided by perfSONAR.
  4. Plugable to perfSONARUI.

Implementation Detail

Currently, our implementation make IEPM-BW data (Network data gathered using Nettools between HEP sites) visible to network engineers. There are two steps in order to visualize the data.

  1. Data Retrieval
  2. Visualize Data

Data Retrieval

 There can be two scenerios:

  1. First check for the required data locally. If it is available then just fetch and retrieve it in a standard NM-WG format for that specific data.
  2. If is it not available locally, then query look up service for that required data. It is then the task of look up service, to retrieve the data for you.

Visualize Data

This module accepts data only in a standard NM-WG format. It visualize the topology using an open source graphing API called JUNG and plot the analysis of metric using JFreeChart.
