bit stuffing
Last modified: Wednesday, October 31, 2001
The practice of adding bits to a stream of data. Bit stuffing is required by many network and communications
protocols
for the following reasons:
To prevent
data
being interpreted as
control
information. For example, many frame-based protocols, such as
X.25
, signal the beginning and end of a
frame
with six consecutive 1
bits
. Therefore, if the actual data being transmitted has six 1 bits in a row, a zero is inserted after the first 5 so that the dat is not interpreted as a frame delimiter. Of course, on the receiving end, the stuffed bits must be discarded.
For protocols that require a fixed-size frame, bits are sometimes inserted to make the frame size equal to this set size.
For protocols that required a continuous stream of data, zero bits are sometimes inserted to ensure that the stream is not broken.
