4Consider the byte stuffing protocol described in the text in Figure 3- Marks: 2 byte. Assuming that the FLAG byte is 0x7D and the ESC byte is 4, with the additional constraint that frames are sent as a whole ,' OX7E, stuff the following payload given in hexadecimal format: OxEE567D9A57D. Do not include starting and ending FLAG delimiters, give the answer as a string of hexadecimal digits FLAG Header Payload field Trailer FLAG Original bytes After stuffin A FLAG B | A | | ESC | FLAG | | B A ESCEB | A | | ESC | | ESC | | B A ESC FLAG BA ESC ESC ESC FLAG B A ESC ESC BAESC ESC ESC ESCB Figure 3-4.
