linux-kernel - 在网络编程的上下文中，什么是 "bluebook"？

Question

我的本地标题 /usr/include/linux/if_ether.h具有以下定义:

#define ETH_P_IPV6     0x86DD /* IPv6 over bluebook */

什么是蓝皮书？我从未听说过这个词，粗略的互联网搜索也没有发现任何与网络编程相关的信息。

从互联网文件:

In 1979, Digital Equipment Corporation (DEC), Intel, and Xerox came together for the purpose of standardizing an Ethernet system that any company could use. In September 1980 the three companies released Version 1.0 of the first Ethernet specification called the “Ethernet Blue Book”, or “DIX standard” (after the initials of the three companies). It defined the “thick” Ethernet system (10Base5), based on a 10 Mb/s CSMA/CD (CarrierSense Multiple Access with Collision Detection) protocol. It is known as “thick” Ethernet because of the thick coaxial cable used to connect devices on the network. The first Ethernet controller boards based on the DIX standard became available about 1982.
