(ITU-T) G. 114 recommends no more than 150 ms one way delay for interactive traffic such as Voice-over-IP. If the end-points are separated by a distance of d, where d is 1000 meter, length of the packet is 100 bits, and propagation speed is 2.5 x 10⁸ meter/sec, what should be the speed of the transmission system (link speed) to support this requirement? Assume negligible queueing delay and processing delay.
