[ns] how can i print the policer table in FTP sources?
dear all, I am doing the project in Network simulator.In that I am doing in differentiated services.I wrote the pogram in OTCL.But the problem is i cannot print the policer table Output in ftp sources where as i can print it in UDP sources.but my aim is to print in Ftp source.so please help me.to print in FTP Thank you K.karthik - Jiyo cricket on Yahoo!

Re: [ns] is address_ the routing address of a node?
This is definitely not a simple/good idea.
Each node is represented by multiple addresses, see
http://tagus.inesc-id.pt/~pestrela/ns2/ns2_haddr_tips.html, so you must make
sure that everything is updated
And most NS2 components probably were designed for constant addresses.
I suggest you try making a reset on the routelogic object to make ns2
recompute the static routes at run-time and use
$ns rtproto Session

Subject: [ns] is address_ the routing address of a node?
I have added the following code in the OTcl
implementation of Node.
Node instproc set-address addr {
$self instvar address_
set address_ $addr
}
During simulation I am using it to change the address
of a node. Eventhough the node address is getting
changed to new value, the node is reachable only with
its old address. Why?
best regards

The god object is showing the # of hops between two nodes at a point of time, but I don't know (from the trace) how to see the number of times a packet has been travered in order to perform a comparison. Does anyone know any good way to do this? Thanks, Sasan
Re: [ns] Newbie questions on wpan demo
Hi, Stan: I read the slides distributed with the wpan modules, but I can only find some descriptions for the commands and cannot find answers to my questions.

[ns] Does ns2 support simultaneous processing ?
Hi I just wanted to know that whether ns2 supports threads or not? Like can more that 2 two stations transmit at the same time It will of gr8 help if some one can post a suggestion -- Saurabh Sinha Department of Computer Science, University of Delhi.
Re: [ns] Newbie questions on wpan demo
2) assoPermit means whether the node should permit other nodes to associate with it so that it becomes their coordinator. Look at the 802.15.4-2003 standard for details. 5) This is not how LossModel is used. Consult ns-manual for the correct usage. It still applies for wpan.

Re: [ns] Trace file
Sara, the simplest way is probably to post-process your tracefile using awk or perl. Modifying the C++ code which generates the tracefile could be very time-consuming, as it is spread among all the implemented agents... Using awk or perl on the ns-2 tracefile you can print only some particular lines. Many references/tutorials/examples of both languages are available on the web. Regards, Marco Fiore Original Message From: [EMAIL PROTECTED] Date: Mar 31, 2006 12:52 PM To: ns-usersns-users@ISI.EDU Subj: [ns] Trace file Hi all, Is there a simple mode to modify the trace file?

Hi all,

However, looking at the code of Distance Vector protocol, the respective

The documentation is referring to the OTcl class hierarchy, and you are
looking at the C++ hierarchy. See line 67 of rtProtoDV.cc:
rtProtoDVclass() : TclClass(Agent/rtProto/DV) {}
