EtherType
読み：イーサタイプ
外語：EtherType
品詞：名詞
外語：EtherType
品詞：名詞
Ethernetで使われる、伝送する通信プロトコルの種類(ネットワーク層の種類)を表わす識別子。
有線LANで使われるEthernet ⅡではEthernetヘッダー内に、IEEE 802.3やIEEE 802.5ではデータリンク層のSNAPヘッダー内に、16ビットで領域が存在する。
Ethernet ⅡでEtherTypeを表わす領域は、IEEE 802.3等ではフレームの長さを表わす領域となっている。このため、0x0800より小さい場合はIEEE 802.3等、0x0800以上の場合はEthernet Ⅱとして区別を行なう。ゆえに、EtherTypeは0x0800〜0xffffの範囲で、原則として定義される。
但し、この原則が決められる前に、0x0800より小さく作られたEthertypeがいくつか存在する。
以下の一覧は、2014(平成26)年4月30日更新時点でのIANAのIEEE 802 Numbers
に基づく。
なお、Ethertypeの番号は全て16進数である。
