Re: [ns] priority queue

[Yan Yu <yanyu@catarina.usc.edu>]

HI, there, 
Thanks for your tip!
I looked up the simple-intserv-sched.cc, here is my understanding what I
should do, but I am sure if it is the right way. if you could give me
some feedback on this, that would be very helpful!
-------
To change a interface queue between LL and MAC layer to separate priotized
queue:

in tcl/lan/vlan.tcl, change the 
"LanNode set ifqType_   Queue/DropTail"
to 
"LanNode set ifqType_   Queue/SimpleIntServ"

or add Queue/SimpleIntServ as a parameter in make-lan command,

and set the flow id in ip header properly based on different priorities of
the packet.

To do the same thing for a normal node( other than a LAN node):
use 
$node add-interface .. to set ifq to Queue/SimpleIntServ,

Thanks a LOT!
