1. (a) Given a baseband bus with station 1 located at 10m, station 2 located at 1000m, and station 3 located at 1010 meters (see diagram above). If the data rate of the bus is 10 Mbps, and the propagation speed of the medium is 200 m/microsecond, how long would it take to send a packet of 100 bits:

(1) between stations 3 and 2?

(2) between stations 3 and 1?

(b) Given a broaband bus with station 1 located at 10m, station 2 located at 1000m, and station 3 located at 1010 meters, and the headend is located at A (see diagram above). If the data rate of the bus is 10 Mbps, and the propagation speed of the medium is 200 m/microsecond, how long would it take to send a packet of 100 bits:

(1) between stations 3 and 2?

(2) between stations 3 and 1?



2. Given a five station token bus LAN with station addresses of 3000, 500, 100, 70, and 50. Stations with addresses of 5000, 4000, 400, 90, and 60 are waiting to enter the ring. Assume a 16 bit address size for the token bus LAN.

(a) Show, in the correct order, each of the MAC control frames that would be sent over the token bus when station 100 attempts to add new station(s) to the ring.

(b) Show, in the correct order, each of the MAC control frames that would be sent over the token bus when station 50 attempts to add new station(s) to the ring.

Use the frame format show below to identify the MAC control frames being sent:



3. Consider a five station token bus network. Calculate the number of frames sent, and the token rotation time (TRTC) for each station, for 5 complete rotations of the token. The priorities of the stations are as follows:

Station Address

Priority

1

6

2

4

3

4

4

4

5

6



Assume the following conditions for the network:

• Time is measured in octet times

• The time to pass the token is 20

• All stations have an unlimited number of frames to send

• The token holding time (THT) for sending priority 6 frames is 400

• The target token rotation time for the priority 4 frames (TRT4) is fixed at a value of 1400

• The frame length is the same fixed value for each station and equal to 100 octets

• The stations are ordered by decreasing station address number
