Can anyone point me to an early reference describing the Internet
protocol layers in IP terms, rather than OSI terms?
One recent text used the following terms. However, I don't know whether
this description has a long history, or is simply revisionist history.
Application
Transport (TCP, UDP)
Internet (IP, etc.)
Network Interface (LAN and WAN technologies).
By 1983 the Internet protocols were already being recast in OSI terms.
Vint Cerf, in "The DoD Internet Architecture Model", described the
following layers:
Application
Utility
Transport
Internetwork
Network
Link
Physical
In May 1979, Jon Postel in IEN-94 ("Internet Protocol Handbook"; it was
small then - 1209 bytes) use the following layers:
Internet Protocol Handbook
Table of Contents
Gateway Level
Internet Datagram Protocol IEN-80
Gateway Routing: An Implementation Specification IEN-30
Host Level
User Datagram Protocol IEN-88
Transmission Control Protocol IEN-81
Multiplexing Protocol IEN-90
Application Level
Name Server Protocol IEN-89
Internet Message Protocol IEN-85
Appendices
Protocol Options IEN-92
Address Mappings IEN-91
Assigned Numbers IEN-93
Does anyone have a pointer to an early, more "traditional", non-OSI
description of the TCP/IP protocol layers?
(By the way, I found the concept behind RFC 157, "Invitation to the Second
Symposium on Problems in the Optimization of Data Communications Systems",
rather interesting. I must admit that I hadn't thought of submitting
spam as an RFC.)
Thanks,
