Hello
Welcome to another issue of RAD at a Glance, the newsletter from
RAD Data Communications about developments in the communications
industry.
ACCESS TRENDS 
Next Generation Internet: IPv6
The current, practically universal Internet
Protocol used today is IP version 4 (IPv4). For a decade
now, the Internet Engineering Task Force (IETF) has been
developing the next version of the Internet Protocol, IPv6.
Addressing the Problem
The anticipated shortage of IPv4 addresses is what motivated the
development of next generation IP. Called IPv6 (or IPng), it constructs
IP addresses from 128 bits (instead of 32 bits as in IPv4), an innovation
that increases available address space by 2 to the 96th power.
But are IP addresses
really limited with the current Internet Protocol? The answer is
yes - and no.
Mechanisms to conserve
IP addresses, such as NAT (Network Address Translation, which hides
several computers at an organization behind a single IP address)
and CIDR (Classless InterDomain Routing, which, roughly speaking,
combines several addresses onto a single route), were so effective
that addresses have not run out, and certain industry analysts predict
that there will be enough IPv4 addresses available for several -
even many - years to come.
That may be the case
in the U.S., which was allotted the bulk of available IP addresses.
However, other regions, such as the Asia-Pacific rim, are already
feeling the address crunch. For this reason, the governments of
Japan and Korea have authorized migration to IPv6 by 2005. And due
to the wide deployment of mobile phones, the European Commission
is advocating that networks involved in research and government
activities also support IPv6 by 2005.
Applications
as the Driving Force
Other players promoting migration to IPv6 include mobile phone companies
such as Nokia and Ericsson, which expect that the rollout of 3G
services will require millions of new IP addresses. Some vendors,
such as Cisco and Checkpoint, are preparing for the shift to IPv6
by offering IPv6 support in their routers and firewalls, respectively.
Advantages of IPv6
include improved addressing and routing, increased security due
to built-in encryption, end-to-end management, increased speeds
due to simplified headers, support for prioritization and classes
of service, easier administration due to auto-configuration and
better support for mobile communications.
However, no enterprise
will swap out its current, operating network unless there is a real
need. And only a handful of service providers - mainly located in
Asia-Pacific, but also one in Seattle, WA - are deploying IPv6 in
the backbone.
IPv6
will become widespread when hundreds of millions of unique IP addresses
are required. Future applications that are expected to drive this
need include everything from 3G mobile telephones and personal digital
assistants (PDAs) to Internet-enabled home appliances such as refrigerators
and microwave ovens, lights and air conditioning. IP addresses will
be required for cars equipped with location and maintenance services,
for fire alarms to indicate their location, and for streetlights
so that municipalities can control them remotely - to cite but a
few applications.
Making the Switch
A gradual migration to IPv6 will ease the financial cost of upgrading
devices to IPv6, but it is still an enormous undertaking for network
managers. Although IPv4 and IPv6 are not compatible, developers
are working on enabling interoperability between the two versions
across the same network. One option is to have routers and servers
support both protocols. Another is to use "tunneling," a method
that would allow IPv6 packets to be carried across IPv4 networks.
RAD is closely monitoring
IPv6 developments for future implementation into its products, in
order to provide IPv6 connectivity and services to the customer
premises. RAD University, the popular on-line computer networking
and communications information source sponsored by RAD Data Communications,
has now posted a new series of tutorial projects to assist its many
visitors in gaining familiarity with IPv6 at
