Also if in case if flag itself is a data i.e 01111110, how would it look after bit stuffing? 0 votes 0 votes OneZero commented Jan 12, 2019 reply Follow Share in case flag is 01111110 we have to insert 1 after 5 consecutive 1's while sending data. so remove 0's after 5 consecutive 1's. bit stuffing is used to differentiate flag from data bits, so NEVER bit stuff flags bucause it beats the purpose of bit stuffing. 0 votes 0 votes balchandar reddy san commented Jan 12, 2019 reply Follow Share you insert 1 or 0? 0 votes 0 votes Rishabh Agrawal commented Jan 12, 2019 reply Follow Share We will insert 0 else it will become flag 0 votes 0 votes VikramRB commented Jan 13, 2019 reply Follow Share @OneZero What would we do in case where flag doesn't have 5 consecutive `1` pattern? 0 votes 0 votes Rajesh Panwar commented Jan 25, 2019 reply Follow Share is it a standard method of adding 0 after every occurrences of 1s? 0 votes 0 votes Please log in or register to add a comment.
