Question: 1. A link with transmission rate Rb = 1 Mbit/s is used to forward packets having constant size L = 1000 byte. Find the time my taken to complete the transmission of a single packet.
2. A link with transmission rate Rb = 1 Mbit/s is used to forward packets having random size , which is assumed to be uniformly distributed in the discrete set L = {1, 2,..., 100} kbyte.
a) Find the mean transmission time my of a packet along the line.
b) Find the probability that the transmission time of a packet is larger than 500 ms.
