1. Create a simple TCL script that can be tested on OneCompiler

A procedure to print node creation and connections (this substitutes NS2-specific commands)

proc create_network {} {
puts "Creating a network with 6 nodes..."
for {set i 0} {i < 6} {incr i} { puts "Node n(i) created"
}

puts "Creating duplex links between nodes..."
puts "Link between n(0) and n(1) created"
puts "Link between n(1) and n(2) created"
puts "Link between n(2) and n(3) created"
puts "Link between n(3) and n(4) created"
puts "Link between n(4) and n(5) created"

puts "TCP connection set up between n(0) and n(4)"
puts "UDP connection set up between n(1) and n(5)"

}

2. Define colors for different data flows (as a conceptual representation)

proc define_colors {} {
puts "Colors for data flows:"
puts "TCP flow: Blue"
puts "FTP traffic: Red"
puts "UDP flow: Green"
puts "CBR traffic: Yellow"
}

3. Simulate the finish procedure (this is placeholder code for actual NS2 behavior)

proc finish {} {
puts "Simulation finished."
}

4. Call the procedures in the order of simulation steps

define_colors
create_network
finish
