Socioeconomic Effects of TCP/IP vs. IsoGrid

This post is excerpted from the IsoGrid Protocol Specification v0.220. If you’d like to skip ahead, check out the spec!

It should be immediately clear to the reader that communication protocols, like TCP/IP, have dramatically changed the world. What is less clear, however, is that the specifics of protocol design can have wide-ranging social and economic effects, some positive, some negative.

Rail Networks are to Road Networks, as the TCP/IP Internet is to the IsoGrid

Economies of Scale
Many networks have a design that reinforces economies of scale. One can see this clearly with the train railroad network: The bigger, more interconnected systems beat out the smaller, less interconnected systems. This also creates huge barriers for new entrants, making it practically impossible for them to compete against the established providers. We submit that economies of scale with the present Internet are creating fewer and fewer providers, and concentrating control in a few individuals in the same way that the rail system of the late 1800s did. This doesn’t have to be the case though. The grid topology of our roadways doesn’t seem to have these same effects. The barrier-to-entry for personal use of the roadways is much smaller compared to that of the railway providers. How small can we make the barriers to entry in the telecommunications market?

The Railroads lead to Railroad Tycoons
The Internet lead to Internet Tycoons
Where are the Roadway Tycoons?
In the same way, the IsoGrid is designed to be less effective than the Internet at centralizing wealth and power.

Isochronous Streams
The “Iso” in IsoGrid is short for Isochronous, meaning ‘same time’. Isochronous means that bits are sent (and then arrive) at a specific well-defined frequency. A theoretical isochronous stream running at a frequency of 1 MHz would transmit one word of data every millionth of a second. Implementations of Isochronous protocols can operate with statically sized buffers, and bounded latency guarantees. VoIP, Internet video, and Internet radio are best sent over an Isochronous connection. Over 50% of peak Internet traffic is actually perfectly suited to Isochronous streams. The early POTS telephone network operated with an analog audio stream, and so early digital communications protocols that evolved from this network could be considered Isochronous. However, over time, the world has instead settled on a packetized asynchronous solution, which is now called the Internet.
Being based on packets, the Internet has terrible support for isochronous connections. This is why your YouTube movies always need to ‘buffer’ before playing: It’s sending a few seconds (or more) of the video to the recipient before it starts playing so that it can compensate for the randomly-timed delivery of packets. If the net had support for true isochronous connections, then it would be possible to watch YouTube and Netflix videos without having to wait for the ‘buffering’ to complete.

At its core, IP allows a maximum of 255 hops for any packet. This inherently restricts the topology of the Internet: As it stands, it can never be a world-wide mesh. Instead, you end up with large hubs and choke-points.
So far, all attempts to create interop standards for nodes that can hop between networks have been unsuccessful. The IP addressing scheme also makes it very difficult to have a mesh: IP addresses are assigned hierarchically.
The name “Inter-Net” describes the problem directly: The Internet isn’t a global network that just anyone can contribute or connect to; instead, the Internet is just a protocol for inter-connecting the world’s centrally owned and operated networks.
