Answer to Question #317714 in Computer Networks for fal

Question

Compare the Go-back N protocol with the rest of the protocols for effective frame transmission in Data link Layer

Answer 1

In Go-Back-N Protocol, if the sent frame are find suspected then all the frames are re-transmitted from the lost packet to the last packet transmitted whereas in selective Repeat protocol, only those frames are re-transmitted which are found suspected.

Sender window size of Go-Back-N Protocol is N whereas in sender window size of selective Repeat protocol is also N.

Receiver window size of Go-Back-N Protocol is 1 whereas in selective repeat protocol, the receiver window size of is N.

Go-Back-N Protocol is less complex whereas in selective Repeat protocol is more complex.

In Go-Back-N Protocol, type of Acknowledgement is cumulative whereas in selective Repeat protocol, type of Acknowledgement is individual.
