[TCP/IP 프로토콜 파헤치기] 2.1 ethernet 프로토콜 스택

2.1 ethernet 프로토콜 스택

[그림 1] ethernet 프로토콜 스택

 

ethernet 프로토콜 스택은 목적지 mac 주소, 발신지 mac 주소와 L3 타입 정보로 구성합니다.

 

ethernet의 mac 주소는 6바이트이며 표기할 때는 12:34:56:78:9a:bc 처럼 1바이트씩 16진수로 나타내고 사이에 콜론(:)을 붙여 나타냅니다.

 

L3타입은 통신에 사용하는 네트워크 계층 프로토콜을 나타내며 IPv4는 0x0800이며 ARP는 0x806입니다. 다음은 네트워크 계층 프로토콜에 따른 L3 타입의 값입니다.
