📄 Passage
Based on the following passage, answer the Questions:
A 3000 km long trunk operates at 1.536 mbps and is used to transmit 64 bytes frames and uses sliding window protocol. The propagation speed is 6 μ sec/km.
If only 6 bits are reserved for sequence number field, then the efficiency of the system is
1.0.587✓ Correct
2.0.875
3.0.578
4.0.50
Solution
Concept:
If only 6 bits are reserved in the sequence number field, then
Maximum sequence numbers possible = 26 = 64
Efficiency = (Sender window size in the protocol / Optimal sender window size)
