The frames are separated by separating flag. Each frame begins and ends with a special bit pattern, 01111110 called a flag byte. When five consecutive l's are encountered in the data, it automatically stuffs a '0' bit into outgoing bit stream.

WebNov 11, 2024 · Bit stuffing is a process of inserting non-information bits into the data to be transferred. It breaks the data sequence and helps in synchronization. In the OSI model, the data link layer divides the data received from the physical layer into data frames. A data frame is classified into two categories: fixed-length or variable-length data frame. WebThe data section is stuffed with an extra byte. This byte is usually called the escape character (ESC) which has a predefined bit pattern. Whenever character as data not delimiting flag. Byte stuffing is the process of adding 1 extra byte whenever there is a flag or escape character in the text.

WebDec 2, 2024 · Byte stuffing is employed to accomplish the task. In byte stuffing an 8-bit flag (‘F’) is added at the beginning and at the end of the frame, thereby distinguishing one frame from the next. Therefore, every time a flag sequence (‘F’) is encountered, it signifies the beginning or end of a frame. This, ingenious scheme, however would give ... WebStarting/ending bytes [byte stuffing] 3.
