Assume a host in Mumbai wants to send a packet to a server in Delhi, approximately 1510 km away. If the signal travels at 2 × 106 m/s, what is the one-way propagation delay in milliseconds? NOTE: Assume no processing or queuing delay(in ms).
If the one-way latency between two cities is measured to be 15 ms, the RTT (Round Trip Time) assuming symmetric paths and no processing delay is:
A transmitter sends packets of size 2000 bits at a rate of 3 Mbps from node X to node Y. The one-way delay is observed to vary between 20 ms (no queueing) and 120 ms (maximum queue), with an average of 60 ms. Assume queuing occurs only at one router along the path and there is no packet loss. What is the mean number of packets in the queue at the bottleneck link?
