Hello, I have create in C++ a new queue with diffserv configuration, with 2 virtual queue, one with high priority and the other with lower, so packets in queue with high priority are dequeued allways and when this queue is empty or one packet in the second priority queue has expired the rtt, then this packet is dequeued. My question is, how can I calculate the RTT? Thanks!!!!!!
