[ns] how to use PriQueue
Can anyone provide a link OR an example on how to use PriQueue (Priority Queueing)? What should be done more in addition to specify DropTail/PriQueue while setting up a link? As I suppose I need to set-up some parameters for settiing priorities for different traffic types, Do I..?? How can I do it?? -- Kamal

Re: [ns] Makefile:233: *** commands commence before first target. Stop.
though not familiar with this paper's detail or code it seems to me a configuration problem. check out path etc. and also source code (whether written for earlier or later versions). did you need to install their piece of code, if yes, then using it directly on an ns already on ur system might not be feasible. good luck.

[ns] Fwd: help needed flow monitoring
1. how do i interpret the per flow trace file? It depends what performance parameters you ld like to look at. So first check that. Once done, approach packet by packet, read notes Eitan Altman's notes on ns2 on how to use trace files. (how to extract useful interepretation). 2. how do i make a study of the service time recieved by each flow? im using a FIFO discipline well better check packets.. and thus flow's arrival time at a node and then at what time its departed.. be careful abt the kind of distribution u use. good lucK thanks -- keep mailing urs @ditya -- Kamal -- Kamal

Re: [ns] how to record number of packets arrived within a time period in tcp
just look at (either last or second last) parameter in the trace file and you know the number of packets arrived at the destination. Dont forget to check that it's +r on destination side.

How do I trace tcp packet arrivals in sink. Is there any parameters , like npkts_ in LossMonitor agent. Thanks. - Jiyo cricket on Yahoo! India cricket Yahoo!
