TYPE: [SPECIFICATION] ISO Model
DESCRIPTION: In the late 1970s, two projects began
independently, with the same goal: to define a unifying standard for
the architecture of networking systems. One was administered by the
International Organization for Standardization (ISO), while the
other was undertaken by the International Telegraph and Telephone
Consultative Committee, or CCITT (the abbreviation is from
the French version of the name). These two international
standards bodies each developed a document
that defined similar networking models. In 1983, these two documents were
merged together to form a standard called The Basic Reference Model
for Open Systems Interconnection. That's a mouthful, so the standard
is usually referred to as the Open Systems Interconnection Reference
Model, the OSI Reference Model, or even just the OSI Model.
It was published in 1984 by both the ISO, as standard ISO 7498, and
the renamed CCITT (now called the Telecommunications Standardization
Sector of the International Telecommunication Union or ITU-T)
as standard X.200. The OSI Reference Model
was intended to serve as the foundation for the establishment of a widely-adopted
suite of protocols that would be used by international internetworks—basically,
what the Internet became. This was called, unsurprisingly, the OSI Protocol
Suite. Popularity of the Internet and its TCP/IP
protocols met the OSI suite head on, and TCP/IP won. Some of the OSI protocols were implemented,
but as a whole, the OSI protocols lost out to TCP/IP when the Internet
started to grow. The OSI model itself, however, found
a home as a device for explaining the operation of not just the OSI
protocols, but networking in general terms.

TYPE: [SPECIFICATION] X.400
DESCRIPTION: The X.400 specifications were first published by ITU-T (then
CCITT) in 1984, and were substantially revised in 1988. The X.400
architecture originated from IFIP WG 6.5, on International Computer
Messaging, and was intended to be able to handle store-and-forward
electronic mail, with interfaces into telex, fax, teletex and postal
mail. In X.400 terminology, a User Agent (UA) is the email client which someone uses
to generate a message and submit it to a Message Transfer Agent (MTA),
which passes the message to other MTAs until the message reaches the
destination user, or until it is converted to a service outside of X.400,
such as being reformatted into a telex, fax, or is printed out and delivered
via a postal service. Compared to Internet mail, the X.400 design enforces more of a logical
separation between the envelope, which contains the fields manipulated by
the MTAs, and the content of the message. The original content forms were
named P2 and P22, and represent a business memo. These forms of content
consist of a header, resembling a cover sheet on a memo, and one or more body
parts. Each body part could be text or an image, such as a fax. (See Also: "Origin of Directory Naming Attributes" http://www.ldap.com/1/x400schema.shtml )
