Question

Consider a bit stuffing framing method where the start of a frame is indicated by 6 consecutive ones, followed by 2 zeroes. What should be the bit stuffing rules at the transmitter? What should be the bit destuffing rules at the receiver? Fill in the blank to show what is the stream after bit stuffingWrite the rule for stuffing:Write the rule for destuffing:Assume the user data stream before bit stuffing is 011111100011111101. What is the stream after bit stuffing?

Answer:

Explanation:

Bit stuffing Framing Method

In the given situation, the beginning casing is shown by 6 sequential ones followed by 2 zeroes.

The beginning casings are generally known as the flags.which are utilized for demonstrating the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the reciever.

Along these lines here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).

To enable us understand how this question plays out, let us understand the rule for Stuffing and De-stuffing .

The standard for stuffing is :

At whatever point there are 5 successive ones supplement one zero in the casing which is an information. The embedded zero piece is known as the stuffed bit.The principle reason behind stuffing somewhat after 5 back to back ones is to evade the distortion of information (data) as flag. If the reciever misconstrues the information as end banner then he would quit recieving the information where the entire information sent by the sender will be left and lost causing an error-prone information.

The rule for destuffing :

The standard/rule for destuffing is only inverse as stuffing. After recieving the bitstuffed information (data), at the reciever's end zero after each 5 continuous ones will be evacuated and the rest of the information will be considered as the genuine information.

In the given situation, the beginning casing is demonstrated by 6 back to back ones followed by 2 zeroes.

the beginning casings are normally known as the flags.which are utilized for showing the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the receiver.

In this way here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).

• data before bit stuffing is:  011111100011111101

• the stream after stuffing would be: 01111101000111101101

where the bolded/underlined digits represents the stuffed bits

cheers i hope this helps
