Outline• newGBNSC• JAVA GUI JAVAGUI

newGBNSC

CP

WUGS

Network



newGBNSC

• Function– Sends (receives) commands cells to(from)

WUGS– Communicates w/ external processes (Jammer,

JAVA Gui)• provides interface to send command cells & receive

returned data

• provides periodic operations



Running newGBNSC

• Location:executable: wu_arl/wugs/bin

source: wu_arl/wugs/src/newGBNSC

README: wu_arl/wugs/src/newGBNSC/README

• 2 executables– newGBNSC.init: reads & writes registers and

vxtable– newGBNSC: read-only



JavaGUI

• Function: monitors live switch discard rates & bandwidths– graphs parameters in units of Mb/s– several switches may be monitored on one

graph– period of monitoring is set by user with rates up

to ~1/30000s– interfaces with newGBNSC



Running JavaGUI• Requirements

– Java 1.2.x runtime environment– newGBNSC or newGBNSC.init running on

switches to be monitored

• Locationwu_arl/msr/apps/javaGUI/pubgui.jar

README file in wu_arl/msr/apps/javaGUI/

• Starting– Windows : double click on pubgui.jar icon– Unix: java -jar pubgui.jar

Converting Parameters

• Parameters are displayed in Mb/s

• Cell Counts are converted to Mb

• Count differences are computed for each polling period and divided by the period length



Starting A New Graph

•Select Start New Graph from Options Menu

•Type Graph Name in text box

•Press Enter



Adding Parameter to Graph

• Select Add Parameter from Graph’s Options Menu

• Select Switch from Monitor Switch Menu

• Select Parameter to monitor from Switch Graphic

• Type Period of updates in Polling Rate Window

Polling Rate Window

• Release mouse button

• Click inside rectangle to Zoom

• To cancel click outside of rectangle

Zoom Out • Select Zoom Out from Graph’s

Zoom Menu



Add New Switch

•Switch ID (arbitrary number for now)

•Name of host running newGBNSC for switch

•TCP port number of newGBNSC

•Select Add Switch from Monitor Switch Menu

•Fill in fields of text window & Press Enter

•Switch added to list stored in file userHomeDir/switches.txt



Saving/Loading Files

•A shortcut for saving a set of graphs frequently used

•Files contain parameter and graph specifications

•Loading a file automatically

•starts a set of saved graphs, •connects to the switches •and sends the commands to start monitoring the specified parameters



Saving/Loading Files Cont’dSaving to File

•All displayed graphs

• Select Save To File from main window’s Options menu
