Abstract

The history of computer communication contains many examples of efforts to align the capabilities of processors to that of communication media. Packet switching is the classic case of a careful tradeoff between the costs of memory, processing, and communications bandwidth.

Gigabit Network Economics and Paradigm Shifts

Status of this Memo

This memo proposes a new standard paradigm for the Internet

Activities Board (IAB) standardization track. Distribution of this

memo is unlimited.

1. Introduction

The history of computer communication contains many examples of

efforts to align the capabilities of processors to that of

communication media. Packet switching is the classic case of a

careful tradeoff between the costs of memory, processing, and

communications bandwidth.

With all of the attention and publicity focused on gigabit networks,

not much notice has been given to small and largely unfunded research

efforts which are studying innovative approaches for dealing with

technical issues within the constraints of economic science. This

memo defines one such paradigm.

2. Contemporary Network Economics

Recent cost estimates predict a continuing decline in the cost for

processing, memory, and communication. One recent projection put the

decline for $/bit and $/MIP at 99% per decade and put the decline for

$/bps at 90% per decade. Scalable parallel processor designs may

accelerate the cost declines for CPU and memory, but no similar

accelerated decline should be expected in the cost of communications.

Such a decline would imply eventual declines in the cost of 56Kbps

service used for voice, resulting in a negative rate of return for

telecommunications carriers, an unlikely eventuality even if free-

market forces are carried to their logical extreme.

Increases in processing power create additional demand for

communications bandwidth, but do nothing to pay for it. While we

will sell no paradigm before its time, the 9% difference,

particularly after compounding is taken into account, will bankrupt

the internet community unless a paradigm shift takes place.

3. The ULS Paradigm Shift

The ULS paradigm shift breaks the downward spiral by concentrating on

end-to-end datagrams and virtual circuit services operating in the

.01 uGbps region, namely Ultra Low Speed networking.

However,

"The worlds best technological paradigm shifts are useless unless

they (a) are economically viable, (b) have clear applicability, (c)

are technically feasible."
