A client sends a 128-byte request to a server located 100 km away over a 1-gigabit optical fiber. What is the efficiency of the line during the remote procedure call? We assume the speed of light in fiber optics is 200 km/msec, and treat 128 bytes as 1000 bits.

network. ii. Consider an application that transmits datalat a steady rate.(for example, the sender generates an N-bit unit of data every k time units, where k is small and fixed). Also, when such an application starts, it will continue running for a relatively long period of time. Answer the following questions, briefly justifying your answer: Would a packet-switched network or a circuit-switched network be more appropriate for this application? Provide reason for your answer. iii. Discuss the difference between best effort delivery and guaranteed delivery. Give two examples for each delivery.

Suppose a file of 10,000 bytes is to be sent over a line at 2400 bps. A. Calculate the overhead in bits and time in using asynchronous communication. Assume one start bit and a stop element of length one bit, and 8 bits to send the byte itself for each character. The 8-bit character consists of all data bits, with no parity bit. B. Calculate the overhead in bits and time using synchronous communication. Assume that the data are sent in frames. Each frame consists of 1000 characters = 8000 bits and an overhead of 48 control bits per frame. C. What would the answers to parts (a) and (b) be for a file of 100,000 characters?
