A Standard for the Transmission of IP Datagrams on Avian Carriers
Status of this Memo
This memo describes an experimental method for the encapsulation of
IP datagrams in avian carriers. This specification is primarily
useful in Metropolitan Area Networks. This is an experimental, not
recommended standard. Distribution of this memo is unlimited.
Overview and Rational
Avian carriers can provide high delay, low throughput, and low
altitude service. The connection topology is limited to a single
point-to-point path for each carrier, used with standard carriers,
but many carriers can be used without significant interference with
each other, outside of early spring. This is because of the 3D ether
space available to the carriers, in contrast to the 1D ether used by
IEEE802.3. The carriers have an intrinsic collision avoidance
system, which increases availability. Unlike some network
technologies, such as packet radio, communication is not limited to
line-of-sight distance. Connection oriented service is available in
some cities, usually based upon a central hub topology.
Frame Format
The IP datagram is printed, on a small scroll of paper, in
hexadecimal, with each octet separated by whitestuff and blackstuff.
The scroll of paper is wrapped around one leg of the avian carrier.
A band of duct tape is used to secure the datagram's edges. The
bandwidth is limited to the leg length. The MTU is variable, and
paradoxically, generally increases with increased carrier age. A
typical MTU is 256 milligrams. Some datagram padding may be needed.
Upon receipt, the duct tape is removed and the paper copy of the
datagram is optically scanned into a electronically transmittable
form.
Discussion
Multiple types of service can be provided with a prioritized pecking
order. An additional property is built-in worm detection and
eradication. Because IP only guarantees best effort delivery, loss
of a carrier can be tolerated. With time, the carriers are self-

regenerating. While broadcasting is not specified, storms can cause
data loss. There is persistent delivery retry, until the carrier
drops. Audit trails are automatically generated, and can often be
found on logs and cable trays.
Security Considerations
Security is not generally a problem in normal operation, but special
measures must be taken (such as data encryption) when avian carriers
are used in a tactical environment.

Auch mein Favorit. Aber das habe ich ja gestern schon im IRC kundgetan. Eine weitere Frage: Wie langweilig muss jemandem sein ...?

Du solltest den Titel deines ersten Posts aber irgendwie ändern Vaneth, da IP ja immer noch benutzt wird (layer 3), und die beiden unterliegenden layer 1 und 2 ersetzt werden.
Layer 2 wäre in diesem Falle die Art und Weise wie Frames an Tauben festgebunden werden, und Layer 1 wäre die Taube selber (verbunden mit dem Raum den sie durchfliegt).
edit:
1999 Wurde der Standard übrigens erweitert und im RFC2549 beschrieben:

IP over Avian Carriers with Quality of Service
Status of this Memo
This memo defines an Experimental Protocol for the Internet
community. It does not specify an Internet standard of any kind.
Discussion and suggestions for improvement are requested.
Distribution of this memo is unlimited.

Abstract
This memo amends RFC 1149, "A Standard for the Transmission of IP
Datagrams on Avian Carriers", with Quality of Service information.
This is an experimental, not recommended standard.
Overview and Rational
The following quality of service levels are available: Concorde,
First, Business, and Coach. Concorde class offers expedited data
delivery. One major benefit to using Avian Carriers is that this is
the only networking technology that earns frequent flyer miles, plus
the Concorde and First classes of service earn 50% bonus miles per
packet. Ostriches are an alternate carrier that have much greater
bulk transfer capability but provide slower delivery, and require the
use of bridges between domains.
The service level is indicated on a per-carrier basis by bar-code
markings on the wing. One implementation strategy is for a bar-code
reader to scan each carrier as it enters the router and then enqueue
it in the proper queue, gated to prevent exit until the proper time.
The carriers may sleep while enqueued.
For secure networks, carriers may have classes Prime or Choice.
Prime carriers are self-keying when using public key encryption.
Some distributors have been known to falsely classify Choice carriers
as Prime.
Packets MAY be marked for deletion using RED paint while enqueued.

Weighted fair queueing (WFQ) MAY be implemented using scales, as
shown:
__
_____/-----\ / o\
<____ _____\_/ >--
+-----+ \ / /______/
| 10g | /|:||/
+-----+ /____/|
| 10g | |
+-----+ .. X
===============================
^
|
=========
Carriers in the queue too long may leave log entries, as shown on the
scale.

sites.

|_____________________________________________
Avian carriers normally bypass bridges and tunnels but will seek out
worm hole tunnels. When carrying web traffic, the carriers may
digest the spiders, leaving behind a more compact representation.
The carriers may be confused by mirrors.
Round-robin queueing is not recommended. Robins make for well-tuned
networks but do not support the necessary auto-homing feature.
A BOF was held at the last IETF but only Avian Carriers were allowed
entry, so we don't know the results other than we're sure they think
MPLS is great. Our attempts at attaching labels to the carriers have
been met with resistance.
Waitzman Experimental [Page 2]
RFC 2549 IP over Avian Carriers with QoS 1 April 1999
NATs are not recommended either -- as with many protocols, modifying
the brain-embedded IP addresses is difficult, plus Avian Carriers MAY
eat the NATs.
Encapsulation may be done with saran wrappers. Unintentional
encapsulation in hawks has been known to occur, with decapsulation
being messy and the packets mangled.
Loose source routes are a viable evolutionary alternative enhanced
standards-based MSWindows-compliant technology, but strict source
routes MUST NOT be used, as they are a choke-point.
The ITU has offered the IETF formal alignment with its corresponding
technology, Penguins, but that won't fly.
Multicasting is supported, but requires the implementation of a clone
device. Carriers may be lost if they are based on a tree as it is
being pruned. The carriers propagate via an inheritance tree. The
carriers have an average TTL of 15 years, so their use in expanding
ring searches is limited.
Additional quality of service discussion can be found in a Michelin's
guide.

Specification of Requirements
In this document, several words are used to signify the requirements
of the specification. These words are often capitalized.
MUST Usually.
MUST NOT Usually not.
SHOULD Only when Marketing insists.
MAY Only if it doesn't cost extra.
Security Considerations
There are privacy issues with stool pigeons.
Agoraphobic carriers are very insecure in operation.
Patent Considerations
There is ongoing litigation about which is the prior art: carrier or
egg.

Gratis Taler im Habbo? Vergesst es!

Ich wollte euch hier mal aufklären über sogenannte gratis Taler im HabboHotel (Habbo ~ Home). Der wichtigste Punkt:
ES GIBT KEINEGRATIS TALER!
Es gibt Leute die sagen: "Ruf unter der Taler Hotline an und gib den Code 45960 ein, dass ist der MOD-Taler-Code". Das stimmt NICHT! Die Moderatoren (MOD) von Habbo haben keinen gratis Taler Code! Wenn du unter diesem Code anrufst, dann schenkst du einem anderen Habbo die Taler!
