Answer to Question #318953 in Computer Networks for pal

Question

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

Answer 1

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.In selective Repeat protocol, only those frames are re-transmitted which are found suspected.

2.Sender window size of Go-Back-N Protocol is N.Sender window size of selective Repeat protocol is also N.

3.Receiver window size of Go-Back-N Protocol is 1.Receiver window size of selective Repeat protocol is N.

4.In Go-Back-N Protocol, neither sender nor at receiver need sorting.In selective Repeat protocol, receiver side needs sorting to sort the frames.
