NS2 Forum

Objectives of ns2 simulation:

• Identify and state functional requirements.
• Identify ambiguities, inconsistencies and incompleteness from a requirements specification.
• Identify and state non-functional requirements.

Sample code for ns2 forum:

This is the sample code for how to load the size-aware classifier to node in network.
set cls [new Classifier/Hash/SizeAware 128] $cls set default_ -1
$cls set flowlen_thr_ 5
$cls set refresh_intv_ 2
$cls set dynamic_update_ 0
set n(0) [node_with_classifier $cls]

In tcl, the nam and trace files are the output files. This is the code for creating the output files.
#To create the trace files we write
set tracefile1 [open out.tr w] $ns trace-all $tracefile1

#To create the nam files we write

set namfile1 [open out.nam w] $ns namtrace-all $namfile
