A bursty source produces data at an average rate of 5 Mbps and its maximum burst rate is 20 Mbps. Packet size is P bits. If a biased exponential distribution is used to model the inter-arrival time, estimate the position parameter and the shape parameter.

Answer #1

a is position parameter

b is shape parameter

average = a + 1/b = 5

20 = 1/b^2

hence b = 1/sqrt(20) = 0.2236

a = 5 - 1/0.2236

= 0.5277

A network transport protocol uses Selective-Reject ARQ. The network data rate is 100 Mbps and the distance between the sender and the receiver is 36,000 km. Assuming an average packet size of 100,000 bits and a media propagation velocity of 3 x 108 m/s, find the window size required for maximum network utilization and the number of bits needed for the sequence numbers.

1. Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 6 customers per hour or 0.1 customers per minute. Also assume that the service times for the drive-up teller follow an exponential probability distribution with a service rate of 54 customers per hour, or 0.9 customers per minute. Determine the...
