[ns] Rate of CBR Traffic ?
Hi aditya, when an event arrives suddenly for example the load of network is important, I will need to reduce the rate. at the beginning I do not have idea of the time of arrival of this event. thanks a lot Aditya [EMAIL PROTECTED] a écrit : Hii $ns at 1.0 $cbr set interval_ 0.05 This will change the rate at 1.0 time instance. You can change it any number of times. Bye. On 3/6/07, leticia bela wrote: yes that fix it statically. but how to dynamically change this rate during simulation (dynamiquely). Thanks a lot Aditya a écrit : Hii $cbr set interval_ 0.05 This is how u can specify interval between 2 packets. I hope this wll solve ur problem.

Re: [ns] Rate of CBR Traffic ?
Hi leticia, My knowledge of ns2 is very limited so you need to specify abit more... where is your code that checks the load of the network for example. When it reaches a set threshold, can't you just call $cbr set interval_ 0.05? If you need to set the rate from cc code then you could do like this: char out[100]; sprintf(out, $cbr set interval_ 0.05); Tcl tcl = Tcl::instance(); tcl.eval(out); $cbr set interval_ 0.05 is sent as a tcl commando to the interpreter and the interval is changed. This is very similar to the ns2 Tutorial for creating a Ping agent: http://www.isi.edu/nsnam/ns/tutorial/nsnew.html#fourth Hi aditya, when an event arrives suddenly for example the load of network is important, I will need to reduce the rate. at the beginning I do not have idea of the time of arrival of this event. thanks a lot Aditya [EMAIL PROTECTED] a ??rit : Hii $ns at 1.0 $cbr set interval_ 0.05 This will change the rate at 1.0 time instance.

Re: [ns] Rate of CBR Traffic ?
Two suggestions: Call/invoke TCL from C, read the user manual and it provides examples of how to do that. Then you can use this command to change the rate. Alternatively, look for command method for CBR class and the associated C code for that class that handles set interval; then you should invoke similar code from the C code that determines when the network load is high or low.
