Virtual Network Visualizer The Last Procedure: Tanis Lopez Brett Papineau Grant Boomer Archana Shrestha
Overview • Project Description • Architecture and Design • Implementation • Documentation • Demo • Possible Additions • Future Development
Project Description Customer • Dr. Jim Alves-Foss, CS Dept. • Intent: Develop a visual way of representing a VMWare Virtual Network with a variable number of nodes and specified links between nodes
Scripting • PowerCLI • Power Shell 2.0 • .Net Framework
Retrieving Data From VMWare • Direct Access to Server • Not through VM Infrastructure Client • Uses Cmndlets to query server • Returns Objects • Multiple responses are stored in Array
Using VMPowerScript • Simply run the script in PowerCLI! • Must Be connected to a Server. • Currently only support one server (Proton or Neutron) • Provide a write path. • Requires a change in how students interact with R.A.D.I.C.L.
Why a Script? • Complete Decoupling from Visualizer • Easy Format. • Students can write own scripts or modify VMPowerScript • Need to follow format restrictions. • Can retrieve what information they need. • PowerCLI offers a powerful alternative to VM Infrastructure
Parsable Document <node> Name Field1 Field2 Field3 <edge> connect1,connect2 <node> vSwitch0 Type: Virtual Switch ID: key-vim.host.VirtualSwitch-vSwitch0 NIC: vmnic0 <edge> proton.radicl.uidaho.edu,vSwitch0
Document Processing • The document is processed using Java API’s • Each node has an associated name, and an additional 3 fields • Entered into the Hash Maps by its tag type
Internal Data Structures • Hash Maps • NodeTable • EdgeTable • HashMaps allow null keys and values unlike a hash table.
Graphical Mapping • The base is a parent child node structure • Balloon Layout gives a clearer viewing mode • Implemented by JUNG2 library.
Graphical User Interface • Main Visualization Canvas • Contains the graph layout • Allows for transforming and picking • User Panel • Contains buttons for zoom, layout, and reset • Contains a textarea for node data output
Documentation • SDD • SRS • Test Plan • Manual(s)
Open Defects File writing error that can only be overcome by creating a new document and pasting in the contents from the script. No support for a structure that has multiple parents connected to a single child. Can be from duplication.
Possible Additions • Arbitray Number of Data Fields • Selected Desired Information via Command Line Arguments • Support for Multiple Servers
Further Development • Direct Interface with VMWare • Yes! It is Possible! • Would be an entirely new project.
Conclusion • Project Description • Architecture and Design • Documentation • Demo • Possible Additions
