overview
This guide considers the internet and the broader global
information infrastructure. It includes a discussion of
key technologies, sectors such as internet hosting and
management issues such as private networks and VoIP.
contents of this guide
The following pages cover -
- issues
- what are the key issues and processes in developing
and maintaining standards for global information networks
- primers
- introductions to network technology, ie background
for understanding legal, economic and other questions
- engineering
& standards - a map of the engineering
bodies - the IETF, ITU and others - along with perspectives
on their operation
- addressing
- what is involved in identifying points on the network,
such as websites, and why that's currently perhaps the
most contentious aspect of the internet. It covers the
DNS, ICANN and ENUM
- infrastructure
- the shape of the global infrastructure: pipes, routers,
ISPs
- traffic
& access - pricing, access and who deals
with domestic and international traffic, particularly
important if (like Australia) your country runs an information
deficit in traffic across the Pacific
- Australia
- a map of official and other bodies in Australia concerned
with the network: ACMAA, SPAN, TIO, ATUG, auDA and others
- advocacy -
advocacy and professional/technical bodies that increasingly
influence how the network is managed
- convergence -
the web, voice and broadcasting networks
- broadband -
a look at broadband, the revolution 'just around the
corner'
- wireless,
pans and piconets - Wi-Fi, Wi-MAX, satellite and other
technologies
- private
- corporate private networks (aka VPNs), proposals for
a 'private internet' devoted to kids or other users,
and writing about the 'deep web'
- voice
- internet telephony, aka VOIP
- ISPs
- the internet service provider industry: technology,
business, regulation, statistics, studies
- hosting
and processing - server farms and other hosting developments
and e-commerce facilitation services
- devices
- end points on the GII: personal computers, phones,
PDAs ...
- mobiles
- questions about mobiles (cellphones) in advanced and
developing economies
- dark
fibre - overcapacity and undercapacity in national
and global telecommunication infrastructure
- neutrality
- debate about network access and traffic prioritisation
Specific
issues, such as domain name disputes, are examined in
more detail in other guides and profiles on this site.
The Governance guide
for example explores the regulation of cyberspace at the
local, national and international level. There are supplementary
profiles on Wireless Access,
on ICANN, on auDA
and on Cybercafes & Telecentres.
orientation
What has been characterised as 'cyberspace' or as 'The
Internet' involves the interrelationship of four layers
-
- the
physical infrastructure layer - the communications links
(much of which predate the net) such as copper wire,
wireless and optic fibre, the switches and devices such
as personal computers, mobile phones and servers
- the
logical layer - connecting the physical infrastructure,
eg Internet Protocol (IP)
- the
applications layer, eg web browsers
- the
content layer
The
web is one part of the internet, an international network
of networks that includes the global information infrastructure
(GII) and various national information infrastructures
(NII).
Although the GII is independent of particular proprietary
hardware or software, it reflects broad standards.
Those standards are developed and administered by national
and international bodies. Some are government agencies;
others are commercial or non-government organisations
that operate with government endorsement.
As a result, responsibilities and processes can be confusing.
The following pages identify standards issues and processes,
highlighting what they mean for Australia and New Zealand.
This guide provides a map of the overseas bodies that
develop or authorise those standards and highlights emerging
technologies such as the wireless web, the basis of m-commerce.
It describes local regulatory agencies such as the ACA,
industry groups and advocacy bodies. A separate profile
highlights the evolution of the net.
laws?
Investment in networks - which as highlighted in the discussion
of the dot-com bubble resulted
in pain for many service and equipment providers - has
reflected what are claimed as six 'empirical laws'.
In reality those 'laws' are trends which have some value
as predictors of the future in the short-term but may
not always apply and may be affected by consumer/investor
behaviour.
They are -
- Moore's
Law - a restatement of the 1965 prediction
by Intel co-founder Gordon Moore that the number of
transistors that could be placed in a computer chip
(the complexity of an integrated circuit) would double
every year. Moore updated the prediction in 1975 to
doubling every month and in 2003, amid forecasts regarding
the imminent 'death of Moore's law', suggested that
another decade of growth was possible
- Metcalfe's
Law - articulated by ethernet developer and
3Com founder Robert Metcalfe, suggested that the value
of a network is approximately the square of the number
of users of that network (a suggestion often illustrated
with the example of facsimile
machines). Arguments that Metcalfe's Law overstates
the value of adding connections has led some observers
to suggest that the value of a network with n
users is n times the logarithm of n (rather
than n squared). Observers have commented that
hard drive capacity (or more broadly memory) in personal
computers has broadly increased by an order of magnitude
every six years, prompting the rejoinder that increase
may not be indefinite and that file sizes have increased
at a comparable rate
- Cooper's
Law - from wireless innovator Marty Cooper,
reflects his observation that the number of voice calls
over radio spectrum (including mobile
phone calls) had doubled every 30 months for roughly
100 years, with the "effectiveness of spectrum
utilisation in personal communications" improving
by "a factor of around one trillion since 1901"
and a million times since 1950. Cooper predicted that
would continue
- Edholm's
Law - from Nortel technologist Phil Edholm,
suggests that data rates for 'fixed', 'wireless' and
'nomadic' communications increase on similar exponential
curves, with the slower rates trailing the faster rates
by a predictable time lag.
- Gilder's
Law - from polemicist George
Gilder, reflects observation that early digital network
bandwidth doubled every nine to twelve months (forecast
in 2000, before anxieties about hard money and dark
fibre took hold, to continue for at least 25 years).
Gilder concluded pre-Crash that internet
traffic was doubling every 100 days and would continue
to do so in future, justifying delirious investment
in connectivity providers and equipment suppliers.
- Goodhart's
Law - offers a caution about conclusions from
such laws, variously articulated as "whenever government
attempts to regulate any particular set of financial
assets, they become unreliable as indicators of economic
trends" or "any observed statistical regularity
will tend to collapse once pressure is placed on it
for control purposes". It has been restated by
Marilyn Strathern as "when a measure becomes a
target it ceases to be a good measure".
Sceptics
add Godwin's Law (articulated by the
EFF's Mike Godwin) - "As an online discussion grows
longer, the probability of a comparison involving Nazis
or Hitler approaches one".
