[ns] How to simulate the TCP stack
Hi, Im new to this group, recently i had downloaded the NS package. It built fine and validate also went fine. my doubt is: How to Validate/Simulate/test the TCP stack ? I had executed the test-all-tcp, whether this will test/validate my active Kernel TCP stack ? mainly, how to allow NS to simulate/validate/test the TCP stack ? Can anybody, please give an idea on this. Thanks Regards, Madhukar Mythri. - Heres a new way to find what you're looking for - Yahoo! Answers
Re: [ns] node genration problem
There seems to be a problem in your routing agent. Match your code
with that of DumbAgent (another routing protocol which does not do
anything): /ns/ns-allinone-2.30/ns-2.30/mobile/dumb-agent.*

[ns] Trace File Generation
Hi, Firstly, thank you for your kind suggestions. Unfortunately, I didn't get any answer to my question as it wasn't a clear one. So, I am wirting my question one more time in a bit more detail. What I need to know is that how the trace file is constructed. I mean, for example, is the line (Event, Time, From Node, To Node, Packet Type, Packet Size, etc.) generated from a C++ file or a TCL file. In other words, is it the output of a C++ file or a TCL file? If so, where can I find this file (that generates each line of the trace file). I need to check, for instance, where the trace file gets its timing, packet type, etc. from. Thanks, Bahman. _ MSN Hotmail is evolving check out the new Windows Live Mail http://ideas.live.com

Hi, A short answer is: the content of a trace file is generated in the ~ns/trace/trace.cc and ~ns/trace/cmu-trace.cc Kind regards Ali Bahman Kalantari Sabet wrote: Hi, Firstly, thank you for your kind suggestions.

Re: [ns] Multi-interface support howto, Ramon Submission
Hello,
Ok, I'm glad that you solved the problems related to the extension. I don't
really know how to address these warnings or whether they are relevant (at
least the virtual destructor one should not).
Cheers,
Ramón

Hi Anthony,
thanks for your feedback; I think that your proposal is perfectly fine.
I've sent an email previously, about the same changes. I think that
the problem was that in the first version of the document we did not
highlight a couple of lines (the ones that you've modified); in the
original ns-mobilenode.tcl file, these two lines started with
$arptable_ **Note the underscore**
In the modified procedure, however, it was $arptable **Without the
underscore**, which is, exactly what you propose, since the $arptable
variable is $arptable_($t).

[ns] ns-2.30 and ns-2.28 installation problems -- otcl configure stopped, etc.
Hi, I met some difficulties when trying to install ns-2.30 and ns-2.28 under Red Hat Linux. Not sure whether anyone had similar experience before and may provide some hints. Thanks in advance. For ns-2.30, I tried both allinone and build from pieces, and had the same error. When running ./configure under otcl-1.12, the process stopped after the following messages: * checking for libtcl8.4... -L/usr/lib -ltcl checking for init.tcl... no checking for http.tcl... no checking Tcl http.tcl library... configure: error: Couldn't find http.tcl in /http /http2.4 /http2.3 /http2.1 /http2.0 /http1.0 ** Then I tried to install ns-2.28 allinone. The configuration and make commands went OK. However, when executing ns binary, even just the simple.tcl under ./tcl/ex, the error message showed: * ns: [code omitted because of length] : no instvar in global :: scope (Object instvar line 1) invoked from within $self instvar id (procedure SplitObject line 2) (SplitObject getid line 2) invoked from within SplitObject getid (procedure new line 2) invoked from within new RNG invoked from within set defaultRNG [new RNG] ** It seems that the simple.tcl hasn't been executed yet...

[ns] Is FTP traffic over TCP connection uses always the same route?
Dear all, I have a topology of 6 nodes: a src, dst and 4 connected routers: Src connected to r1 Dst connected to r4 r1 connected to r2 and r3 r2 connected to r4 r3 connected to r4 Src r1 r2 | | R3---r4---dst I sent traffic from src to dst and monitored the different queues. The problem is that the traffic always passes through r1, r2 and then r4. The queue of r3 is always empty. I tried to modify the queues sizes, the delay etc but I didn't succeed. I thought that TCP connection may take more than one route and the traffic passes via all possible routes. Can anyone help me. Thank you. Mohamed ben Othman
