#CN Given are the sequence number field bits, tell the total sequence number possible and SWS simple SWP? (Self Doubt)

Question

Say sequence # field has 5 bits.

then what would be the max SWS (sender window size) in case of simple SWP where nothing is mentioned explicitly that the SWP is GBN or SN, this info is not mentioned and only said SWP is used. So here how to calculate SWS?

Answer 1

here nothing is mention whether it is GBN or SR

but it there are sequence bit is n

and   in case of GBN sender window size is 2ⁿ-1

but in case of SR sender window size is 2^n-1

so the maximum is 2ⁿ-1 which will be the answer here to find maximum no need to give whether it is GBN or SR because maximum will always be in case of GBN

@Gurdeep Saini Please see this question - https://gateoverflow.in/1267/gate2007-69

and see the best answer, it's mentioned in the end and I quote as - 

Edit : here it is asked for general sliding window protocol not GBN nor SR . 

In general sliding window protocol: 

Sequence number bit =log(sender window size)
