part 1) Given a link with a maximum transmission rate of 90.8 Mbps. Only two computers, X and Y, wish to transmit starting at time t = 0 seconds. Computer X sends fileX (8 MiB) and computer Y sends fileY (233 KiB), both starting at time t = 0.

Computer X gets the transmission medium first, so Computer Y must wait.

For the following calculations, assume maximum transmission rate during transmission.

Suppose that entire files are sent as a stream (no packets, no multiplexing).

At what time (t = ?) would FileX finish transmitting?

Give answer in seconds, without units, and round to two decimal places (e.g. for an answer of 12.4567 seconds you would enter "12.46" without the quotes)

part 2)

Given a transmission medium with propagation rate of 2.5x10⁸ m/sec. Multiple computers share this link using packet switching.

Assume that queuing is necessary only for transmission. (i.e. ignore processing delay for all packets.)

Assume that there is no other traffic on the medium, no switches between the link and the destination

At least 20 packets arrive in the queue at time t = 0.

Each packet's size is 1000 bytes.

The distance to the destination is 1500 km.

Answer the following questions for each of the given transmission rates. Give answers in milliseconds, without units, rounding to two decimal places, for credit. (e.g. for 0.000302 seconds you would enter "0.30" without the quotes)

	10 Mbps	100 Mbps
What is the transmission delay for each packet?
What is the propagation delay for each bit?
What is the queueing delay for the 4th packet?
What is the end-to-end delay for the 5th packet?
What is the average queueing delay for the first 10 packets?
