Question
The throughput of the system on a Slotted Aloha network. The network uses Slotted Aloha, the length of each timeslot is equal to the transmission time of a single packet. Each computer generates 500 packets per second with each packet is 1000 bytes. What is the throughput of the system if there are 10 computers on the network?
A tutor's answer:
S=G×eG
500 packets per second = 1/2 packest per millisecond <---- Can you explain here, why convert to millisecond to do the calculation
S = 1/2*(e{-1/2}
S = 0.30325
Throughput = G*S = 1000 * 0.30325 = 303.25 packets per computer <--- also, what is 1000 here stands for?
Throughput of 10 computers = 10*303.25 = 3032.5 packets
Explanation / Answer
G is the average number of frame/packet start time points within 1 frame/packet slot. and on standard basis G is taken in ms(mili second).
as G is average number of frame/packet start time within 1 frame slot, and S is average successful frame transmissions per frame/packet slot.
so it is for per frame/packet slot and
each frame/packet contain 1000 bytes of data per frame, so throughput 1000*S.
