Character-Oriented Protocols

In a character-oriented protocol, data to be carried are 8-bit characters from a coding

system such as ASCII (see Appendix A). The header, which normally carries the source

and destination addresses and other control information, and the trailer, which carries

error detection or error correction redundant bits, are also multiples of 8 bits. To separate

one frame from the next, an 8-bit (I-byte) flag is added at the beginning and the end of a

frame. The flag, composed of protocol-dependent special characters, signals the start or

end of a frame. Figure 11.1 shows the format of a frame in a character-oriented protocol.


이 부분에서

프레임 = 헤더 + 트레일러 + 데이터 + 플래그로 구성되는 것 같은데요.

질문은

데이터, 플래그 -> 이거는 각 8비트(1바이트)로 고정된 건 알겠는데


헤더, 트레일러 -> 이거는 그냥 8비트의 배수이기만 하면 되는건가요? 8비트, 16비트, 24비트... 다 가능한건가요?
