The Zephyr Protocol is used both for messages delivered to end users of the system and for control and maintenance of the message transport system.
Zephyr clients and servers utilize a common Zephyr Client Library that provides routines for such operations as datagram port setup and shutdown, notice transmission, and notice reception.
When Kerberos is in use, this field is built by the Zephyr server using the quad_cksum routine in the DES library to cryptographically checksum the previous header fields using the DES session key.

  Zephyr protocol - Wikipedia, the free encyclopedia
Created at MIT, as part of Project Athena, Zephyr was designed as an instant messenger protocol and application-suite with a heavy Unix background.
Using the "do one thing, do it well" philosophy of Unix, it was made up of several separate programs working together to make a complete messenging system.
Zephyr is still in use today at few university environments such as CMU, Iowa State, Stanford University, University of Maryland, College Park, and, of course, MIT.

Real-time chat protocol such as IRC are well-suited for interaction with small groups, but require significant involvement in determining 'where' users should meet, often involving another communication channel to coordinate the meeting.

The Zephyr Protocol Greg Hudson 2000-02-17 Protocol entities ----------------- Three different kinds of entities participate in the zephyr protocol: client programs, host managers, and servers.
All Zephyr communications use the same packet format, whether for displayable messages or for control notices internal to the protocol.
The zephyr server enforces that the IP address matches the IP source address of the packet it received.

The Zephyr protocol does not allow users to efficiently communicate with a restricted group of other users; that is, the nature of Zephyr classes and instances does not allow users to control the people subscribed to them without having control of the Zephyr servers.
The Zephyr protocol does not allow the separation of the location service from the other services its provides, nor does it allow for the separation of the personal messaging service from the group messaging service.
The Zephyr library is complex and convoluted, especially in the realm of fragmented notices, and exposes its internals to the application programmer.

Although the protocol was never open, there have been several groups which have attempted to reverse-engineer it.
Zephyr is based on a library that is distributed in the Zephyr source, which is what Purple uses to connect to the Zephyr service.
Zephyr is a UDP-based protocol, and in order to keep messages reliable, it has a "host manager".

There is also a protocol for maintaining multiple copies of the Kerberos database, but this can be considered an implementation detail and may vary to support different database technologies.
If the application protocol is expected to tolerate lost messages without them being resent, the use of the timestamp is the appropriate replay detection mechanism.
Using timestamps is also the appropriate mechanism for multi-cast protocols where all of one's peers share a common sub-session key, but some messages will be sent to a subset of one's peers.

Mark was one folks who worked on Zephyr (here's original paper -- danger, postscript file), so he was in a perfect position to point out some features that XMPP appears to lack (I haven't read all the RFC's).
Zephyr source is in a couple of places - there's a sourceforge project, there should be a somewhat recent version in ftp://athena-dist.mit.edu, and the freshest probably in /afs/dev.mit.edu/source/src-current/athena/lib/zephyr/ (which is probably reachable through various web->afs gateways like www.mit.edu.)
There actually was even a (trivial prototype of a) voice-messaging extension to zephyr - when the NeXT cubes first came out, someone came up with a client that used zephyr to pass socket info and then directly channelled audio over tcp, bypassing the servers.

Zephyr has become the local chat and quick private message tool of choice on the systems I use, and it wouldn't be exaggerating too much to say that a fair-sized community has grown up around its public instance mechanism.
But Zephyr is in no sense a reliable system; users complain about it, sysadmins must deal with it, and system resets require the cooperation of everyone logged in to reset their own client.
Zephyr would certainly not scale up to the Internet as a whole, which puts it at a disadvantage when compared to protocols like ``talk'' or IRC which allow one to communicate with people on arbitrary remote hosts.

As a result of the Montreal Protocol and its amendments, the concentrations of ozone-depleting substances in the lower atmosphere (troposphere) peaked around 1995 and are decreasing in both the troposphere and stratosphere.
At the 18th Meeting of the Parties to the Montreal Protocol in New Delhi, India, the United States received authorization on 91% of its request for critical-use exemptions of the ozone-depleting soil fumigant methyl bromide for the year 2008.
Under the current structure of the protocol, the parties to the treaty authorize exemptions on an annual basis, and each year EPA promulgates a rule to allocate methyl bromide for critical uses.

Public Services Searching via Zephyr One of Zephyr's greatest advantages is that it allows users to search and retrieve information from the CitaDel and RLIN bibliographic files using LIAS commands and displays, eliminating the need to learn a new interface every time they access a new database.

Zephyr returns the primary record in a cluster and includes 952 fields containing the ID numbers for all secondary cluster records.
