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。
概要
有線LANで使われるEthernet ⅡではEthernetヘッダ内に、IEEE 802.3やIEEE 802.5ではデータリンク層のSNAPヘッダ内に、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。
一覧表
以下の一覧は、2008(平成20)年3月19日更新時点でのIANAのethernet-numbersに、いくつかのドラフト段階の番号を追記したものである。ドラフト段階で破棄されたものもある。これらethernet-numbersに無いものは、参照に※を附した。
なお、Ethertypeの番号は全て16進数である。
