Re: [ns] make clean, make depend, make do not take effect
Hi, try make clean, make, sudo make install from /ns-whatever/ns-2.31 directory Filip Hi, Here are my two cents, perhaps one of the following could be the problem: 1. Perhaps you are not executing the make/make clean commands in the right directory, you have to do it in /ns-whatever/ns-2.31 directory or 2. You are not calling the right protocol in your tcl script file e.g. you made some changes in TORA.cc but you are calling AODV in your tcl script file. Hope that helps. - Original Message From: bilge kartal [EMAIL PROTECTED] To: minisivakumar vellore [EMAIL PROTECTED] Cc: ns-users@ISI.EDU Sent: Friday, October 26, 2007 10:46:37 AM Subject: Re: [ns] make clean, make depend, make do not take effect Hi, I had same problem before.

Re: [ns] Could not schedule timer
This query has been posted in past also but my search for the solutions was unsuccessful: When I run my NS script with heavy traffic, the execution sometimes stop in between giving the error as Couldn't schedule timer. I am also using my own timer for acknowledgement timeout. Does this refer to the internal timer or my own defined timer? It seems that this is the internal timer (common/timer-handler.cc), unless you fprint the same text with your own timer. Make sure by e.g. editing the line fprintf(stderr,Couldn't schedule timer); in common/timer-handler.cc to fprintf(stderr,Couldn't schedule timer from timer-handler.cc); Then recompile ns-2, reinstall it, and run your tcl script. If the text that ns-2 prints out matches your changes in common/timer-handler.cc, then you know which timer this text refers to. How can I avoid this error? It seems that your ns-2 sets the timer to idle state somewhere. Try to check where it does it. Tarun Regards, Filip
[ns] How to implement circuit-switching in ns-2?
Hi, I've been trying to implement a circuit-switched network model using ns-2 for some time. I have the following ideas: - use manual routing and separate queues for each flow - add path information to a packet payload - lay more links between a node pair - implement source routing - implement GMPLS/WDM, and base on labels/wavelengths I managed to introduce manual routing for a packet switched-network (add-route command), but I got stuck by defining separate queues for each flow in the first approach. The second approach seems less elegant to me, and I don't know how to add any information to the payload. When I tried the third idea, ns-2 saw just a single link between a node pair, even though there were more links created (using command $ns duplex-link $n($i) $n($j) 1Mb 10ms DropTail but I wouldn't know, how I could refer to each link, as a link doesn't have its name...) Source routing seems to be an interesting approach, but I would still need to define separate queues for each flow... As for GMPLS, WDM, I am aware, that a WDM extension is available for ns (http://dawn.cs.umbc.edu/owns/), but it is not updated any more, and I am not sure if it works with current and with future releases of ns-2. I searched the whole mailing list for GMPLS and WDM, but I didn't find any clear solution for a WDM or GMPLS network. I searched the ns mailing list also for circuit switching, and saw that some people managed to implement circuit-switching, but there is no information on how to do it. Could you please give me some hints on how to implement one of the ideas I presented above, or maybe on a completely another idea? Simply, how to implement circuit-switching in ns-2? Thanks a lot in advance! Filip
