[ns]MPLS question urgent!!

[alaeddine abdallah]

Hi all ns-users,
 
I'm using  ns2.26 version,
 
in my work I need to use MPLS to forward packets in a explicit routes.
 
I've tried the example test-lsp.tcl in the MNS examples directory but i haven't understend those commands:

$ns enable-control-driven

$ns enable-data-driven

$ns enable-on-demand

$ns enable-ordered-control

I want to know the différence between them.

thank you in advance.
