The RFC Series (ISSN 2070-1721) contains technical and organizational documents about the Internet, including the specifications and policy documents produced by five streams: the Internet Engineering Task Force (IETF), the Internet Research Task Force (IRTF), the Internet Architecture Board (IAB), Independent Submissions, and Editorial.
RFC系列(ISSN 2070-1721)包含有关互联网的技术和组织文件，包括由五个流生成的规范和政策文件:互联网工程任务组(IETF)、互联网研究任务组(IRTF)、互联网架构委员会(IAB)、独立提交和编辑。
RFC文件是由Internet Society（ISOC）赞助发行，基本的互联网通信协议都有在RFC文件内详细说明。RFC文件还额外加入许多在标准内的论题，例如对于互联网新开发的协议及发展中所有的记录，因此几乎所有的互联网标准都有收录在RFC文件之中。
