「このページは著作権侵害のおそれが指摘されており、事実関係の調査が依頼されています。」

転載元はよく知らない。 IETFのRFC(request for commnet)だけからの理解をするために、まずRFCを読む

読む目的によって、全部読むか、全部に加えてそれぞれのRFCで参照しているRFCも全部読むか、現在有効な文書だけ読むか、現在重要な文書だけ読むかの4種類を想定

＜この項は書きかけです。順次追記します。＞

重要な文書だけ読む

RADIUSの著名な書籍を読み、その参考文献、引用しているRFCだけ読む。
この方法だと、今回の目的のうち、RFCだけから理解するという作業にならなくなってしまう。

現在有効な文書だけ読む

下記検索結果からObsolatedとなっているもの以外を読む。
ここから始める。

まず、表題にRADIUSの文字があるものだけ最初に読む(1)。

RFC editor search
https://www.rfc-editor.org/search/rfc_search.php

読んだものからURLをつける。

少し作業を進めてみると、
RFC2865,2866, 2867, 2868, 2869の5文書が中核文書だと思ってもいいかもしれない。

もし、構造が変わるのであれば、前の文書をObsolateして、新しい文書番号をつけるはずだから。
（どんどん新しい文書にしていくものと、古い文書を大切にしてUpdateするものもあるかもしれず、かならずしも新番号がつかなければ中核とは限らないかもしれない。）

Radius RFCを全部読む

RFC Editor Searchで、Rasiusで検索した結果が下記。
他の通信規約の場合に、略称が全く出てこない文章もあったような気がする。
全部読む過程で、関連文書、変更文書などが、この一覧にないかを確認する。

Radius RFCで参照しているRFCも読む

ReferenceのRFCを理解していないと、本質的な事項がわからないかもしれない。

例えば、
[4] Postel, J., "User Datagram Protocol", STD 6, RFC 768, August 1980.
はTCPと共存する通信規約で重要である。TCPの上で動くか、UDPの上で動くかで、上の規約の特徴が生きるかどうかがかかっている本質的な参照と、部分的な調整上で参照しているRFCでは必読度が違うかもしれない。
今回は、参照通信規約の重み付けは行なっていない。（重要度を評価するほど理解していない）

用語(term)

RFC3579

authenticator

         The end of the link requiring the authentication.  Also
         known as the Network Access Server (NAS) or RADIUS client.
         Within IEEE 802.1X terminology, the term Authenticator is
         used.

peer

  The other end of the point-to-point link (PPP),
         point-to-point LAN segment (IEEE 802.1X) or wireless link,
         which is being authenticated by the authenticator.  In IEEE
         802.1X, this end is known as the Supplicant.

authentication server

         An authentication server is an entity that provides an
         authentication service to an authenticator (NAS).  This
         service verifies from the credentials provided by the peer,
         the claim of identity made by the peer; it also may provide
         credentials allowing the peer to verify the identity of the
         authentication server.  Within this document it is assumed
         that the NAS operates as a pass-through, forwarding EAP
         packets between the RADIUS server and the EAP peer.
         Therefore the RADIUS server operates as an authentication
         server.

displayable message

         This is interpreted to be a human readable string of
         characters, and MUST NOT affect operation of the protocol.
         The message encoding MUST follow the UTF-8 transformation
         format [RFC2279].

Network Access Server (NAS)

         The device providing access to the network.  Also known as
         the Authenticator (IEEE 802.1X or EAP terminology) or
         RADIUS client.

RFC2865, RFC2866, RFC2869

service

       The NAS provides a service to the dial-in user, such as PPP
         or Telnet.

RFC3579

service

      The NAS provides a service to the user, such as IEEE 802 or
         PPP.

RFC2865

session

        Each service provided by the NAS to a dial-in user
         constitutes a session, with the beginning of the session
         defined as the point where service is first provided and
         the end of the session defined as the point where service
         is ended.  A user may have multiple sessions in parallel or
         series if the NAS supports that.

RFC2866

session

        Each service provided by the NAS to a dial-in user
         constitutes a session, with the beginning of the session
         defined as the point where service is first provided and
         the end of the session defined as the point where service
         is ended.  A user may have multiple sessions in parallel or
         series if the NAS supports that, with each session
         generating a separate start and stop accounting record with
         its own Acct-Session-Id.

RFC2869

session

        Each service provided by the NAS to a dial-in user
         constitutes a session, with the beginning of the session
         defined as the point where service is first provided and
         the end of the session defined as the point where service
         is ended.  A user may have multiple sessions in parallel or
         series if the NAS supports that, with each session
         generating a separate start and stop accounting record.

##RFC3579
###session
Each service provided by the NAS to a peer constitutes a
session, with the beginning of the session defined as the
point where service is first provided and the end of the
session defined as the point where service is ended. A
peer may have multiple sessions in parallel or series if
the NAS supports that, with each session generating a
separate start and stop accounting record.

RFC2865, RFC2866, 2869, RFC3579

silently discard

         This means the implementation discards the packet without
         further processing.  The implementation SHOULD provide the
         capability of logging the error, including the contents of
         the silently discarded packet, and SHOULD record the event
         in a statistics counter.
