In Go Back 3 with a scenario where every 5th packet is lost while sending 10 packets, how does this affect the total number of transmissions?
Understand the Problem
The question is asking about the impact of packet loss on the total number of transmissions in a Go Back N protocol, specifically when every 5th packet is lost while sending 10 packets. It requires an understanding of protocols in networking.
Answer
13 transmissions
The final answer is 13 transmissions.
Answer for screen readers
The final answer is 13 transmissions.
More Information
In Go-Back-N protocol, if a packet is lost, all subsequent packets sent within the window must be retransmitted after the lost packet. If packets 5 and 10 are lost in a series of 10 with every 5th packet lost, it results in 13 total transmissions.
Tips
Common mistakes include not accounting for retransmissions of all subsequent packets after a loss, and not correctly recalculating the number of packets sent after retransmission.
