Web2 days ago · The frame begins with a flag sequence represented by the bit sequence 01111110 and denoted by the value 0x7E. Each byte in the frame undergoes encoding using the HDLC bit-stuffing algorithm, which inserts an additional 0 bits after every sequence of five consecutive 1 bits. In cases where the byte is a control character, such … WebJan 15, 2024 · Byte stuffing actually operates on bytes whereas bit stuffing operates on bits. In Byte stuffing, a special byte known as ESC (Escape Character) with a specified pattern is added to the data section of the data stream or frame when there is a message or character with the same pattern as the flag byte. Byte stuffing is adding one extra byte ...
