Pigeon packets

Quote:
JOHANNESBURG (Reuters) - A South African information technology company on Wednesday proved it was faster for them to transmit data with a carrier pigeon than to send it using Telkom , the country's leading internet service provider.

Internet speed and connectivity in Africa's largest economy are poor because of a bandwidth shortage. It is also expensive.

Local news agency SAPA reported the 11-month-old pigeon, Winston, took one hour and eight minutes to fly the 80 km (50 miles) from Unlimited IT's offices near Pietermaritzburg to the coastal city of Durban with a data card was strapped to his leg.

Including downloading, the transfer took two hours, six minutes and 57 seconds -- the time it took for only four percent of the data to be transferred using a Telkom line.

SAPA said Unlimited IT performed the stunt after becoming frustrated with slow internet transmission times.

The company has 11 call-centers around the country and regularly sends data to its other branches.

Telkom could not immediately be reached for comment.

Internet speed is expected to improve once a new 17,000 km underwater fiber optic cable linking southern and East Africa to other networks becomes operational before South Africa hosts the soccer World Cup next year.

Local service providers are currently negotiating deals for more bandwidth.

The IETF (Internet Engineering Task Force -- the entity responsible for Internet protocol standards) has established several standard for IP over avian carrier:

RFC 1149 - A Standard for the Transmission of IP Datagrams on Avian Carriers

RFC 2549 - IP over Avian Carriers with Quality of Service

:D

Edit:

Code:
   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.

This is not the first instance of RFC1149 being implemented. It is, however, the first to transmit a significant amount of data, I think. A saying developed many years back, "Do not underestimate the bandwidth of a station wagon loaded with backup tapes going 80 miles an hour down the freeway", as a result of a similar set of circumstances requiring data transfer quicker than could be accomplished over a wire. It is not a medium that works well for latency sensitive transfers, though.

That's hilarious.

Yeah, the wiki article on this actually mentions several accounts of this. Like you say, if latency isn't issue, IP over feathered rat actually has pretty decent throughput on a bandwidth averaged basis...

Wikipedia wrote:
Rafting photographers already use pigeons as a sneakernet to transport digital photos on flash media from the camera to the tour operator.[2] Over a 30 mile distance a single pigeon may be able to carry tens of gigabytes of data in around an hour, which on an average bandwidth basis compares very favorably to current ADSL standards, even when accounting for lost drives.[3]

what about data security, it's amazing what a pellet gun can do.

Well, you have to remember that by design, the IP protocol operates only on a "best effort delivery" basis to begin with. If you want data security, it should be used in conjunction with a "stateful" session-level protocol like TCP.

I don't recommend using TCP windowing with pigeons, though. They have a tendency to fly right into the glass.

You can also use encryption, to avoid man in the middle attacks.
