1. Compute the total time required to transmit a100 megabit data set to be transported on a Virtual Circuit packet switched network with acknowledgements. Packet size is 1024 bits including header; header size is 24 bits; average number of hops is 5; propagation delay per hop is 0.001 seconds; average data rate is 1Mbps; and average time to set up a call is 10 seconds. Acknowledgements are exchanged by transmitting the header packet back to the source.

2. What will be the total time required in the above scenario if each switching node has average switching delay time of 1 bit time?
