Dear ns-users! I want to create a simple scenario, where I measure the lost packets on a bottleneck link, but I always get false result. I generate the traffic with a CBR application and pass it through a UDP connection.
My first question is: What is the packet size that is transmitted on the link? Is it the size that is define in the CBRs packeSize_ or the CBR packetSize_ plus the UDP header(8bytes)? I want to generate traffic like an On/Off Bernoulli source would do. E.g. if it is turned On it generates with 64kbps, and if it'd turned Off it generates with 0kbps. This leads to a 0.5 On/Off probability. My second question is: Is it a proper way if I make a link with 64kbps bandwidth and transmit a 32kbps average traffic through it? Thank you in advance! Regards, Endre
