Question: [Networking] Compute the overheads in the belox three framing methods respectively. The overhead is the ratio of the size of the stuffed frame (including delimiters)

[Networking] Compute the overheads in the belox three framing methods respectively. The overhead is the ratio of the size of the stuffed frame (including delimiters) and the size of bit sequence transmitted through data link layer.

Original: A: 01000111 B: 11100011 FLAG: 01111110 ESC: 11100000

after each method is used:

1. Byte count: 00000101 01000111 11100011 11100000 01111110

2. Flag bytes with byte stuffing: 01111110 01000111 11100011 11100000 11100000 11100000 01111110 01111110

3. Starting and ending flag bytes with bit stuffing: 01111110 01000111 11100011 11100000 011111010 01111110
