hi frndz, I m working on simulating the queueing models in NS2. m facing problems in m/m/m simulation when simulating it in tcl/tk. Actually i ve reffered some codes on the net but they do not use nodes and link thing to simulate it. they juz use variables and solve it mathematically. Also if I am getting problems in detecting which server is idle at the time of packet arrival for the longest time. doing it with queues in c++ seems easy but I cudn't understand how to deal wid single queue and multiple servers. Can ne1 help me asap..!!!!! Thnx in advance..
