RFC （ Request for Comments ）

• 在要網路上成為通訊標準，必須向Internet Society 提出。經過大家的監督、測試與使用，才能為大家所接受。

• 審核通過的 RFC Editor 會給與一個編號，成為 RFC 文件。– Example ： FTP 是 RFC-959 、 IP 是 RFC-

791 、 ICMP 是 RFC-792 、 PPP 是 RFC-1661 。

Internet Standards Process

• 成為通訊標準必需經過的步驟稱為Internet Standards Process ：– Internet Drafts– Proposed Standards 、 Draft

Standards 、 Internet Standards (or Full Standards)

• Internet Drafts 提案不具任何實質「標準」地位。

Levels of RFC Documents

• Standards Track Maturity Levels– PS: Proposed standards– DS: Draft standards– S: Internet Standards

• Non-Standards Track Maturity Levels– E: Experimental– I: Information– H: Historic

Internet Assigned Numbers Authority (IANA)

• The Internet Assigned Numbers Authority (IANA) is the central coordinator for the assignment of unique parameter values for Internet protocols. – The IANA is chartered by the Internet Society

to act as the clearinghouse to assign and coordinate the use of numerous Internet protocol parameters.

Internet Engineering Task Force (IETF)

• The IETF is a large open international community of network designers, operators, vendors, and researchers concerned with the evolution of the Internet architecture and the smooth operation of the Internet. It is open to any interested individual.

Active IETF Working Groups

• The actual technical work of the IETF is done in its working groups.– The IETF working groups are grouped into areas (e.g.,

routing, transport, security, etc.). – Working groups are managed by Area Directors (ADs). – The ADs are members of the Internet Engineering

Steering Group(IESG). – The General Area Director also serves as the chair of

the IESG and of the IETF.

Mission of IETF （ 1/2 ）

• Identifying and proposing solution to operational and technical problems in the Internet.

• Specifying the development or usage of protocols and the near-term architecture to solve such technical problems for the Internet.

Mission of IETF （ 2/2 ）

• Making recommendations to the IESG regarding the standardization of protocols and protocol usage in the Internet.

• Facilitating technology transfer from the IRTF to the wider Internet community.

• Providing a forum for the exchange of information within the Internet community between vendors, users, researchers, agency contractors, and network managements.
