And the transfer duration each flow seconds
Identify and explain the events that can change the state of the system [1]
Suppose the arrival times of the first 10 requests are 1, 3, 5, 6, 7, 8, 11, 12, 14, 15 seconds (of simulation time). The data size of each flow is 180+Y Mega bits, where Y = (Your roll number) modulus 30, and the transfer duration of each flow is 5 seconds. Fill the following table. [4]
Average number of messages in the system
Average number of messages in the queue waiting to be transmitted.
Operational time of each machine = 6+C units of time, where C = (Your roll number) modulus 3 Repair time for each machine = 6 units of time
CL1, CL2, CL3 are associated with machines 1, 2, 3 respectively CLR1 and CLR2 tell repairman 1’s and 2’s completion time respectively
| MC | CL1 | CL2 | CL3 | CLR1 | CLR2 | |||
| 0 | 2 | 5 | 5+D? | - | - |

The output buffer of an ATM multiplexer can be modeled using a queue. Constant service time means that an ATM cell has a fixed size (53 octets; each octet is of 8 bits) and its transmission time to the link is constant. If the link speed is 155 Mbps, then the transmission time is S = 53* 8/155 μs = 2.7μs.
What is the mean number of cells in the buffer (including the cell being transmitted?) and the mean waiting time of the cell in the buffer when the average arrival rate on the link is 80+A Mbps, where A = (Your roll number) modulus 20?
