RE: [Embedlets-dev] 1 page JXTA paper for James

[James C. <ca...@vi...>]

Thanks! Ted.. 

Just what I needed.. Now to do (another) pretty picture and integrate
into the doc.. 

BTW - Is there an equivalent technology to JXTA from the Microsoft .NET
croud?

Ok James, here is the paper.  I tried to make it as non-technical as
possible while still getting across the main ideas.  Hope it helps...

Managing billions of Internet-connected Embedded devices using JXTA and
Java.

BILLIONS OF GENERIC NETWORK NODES

JXTA (www.jxta.org) is a new networking technology that allows any
devices that can be connected to the Internet to be treated as generic
network nodes which developers can form into subgroups.  These JXTA
subgroups are a new class of computer, called a "network-based
computer", and developers can dynamically create these network-based
computers out of generic JXTA nodes in order to solve domain-specific
problems.  JXTA technology is designed to scale to billions of nodes and
these nodes can consist of any devices which have electronic "heart
beats", like PCs, cell phones, servers, PDAs and embedded systems.


THE NETWORK *IS* THE COMPUTER

One way to look at how the new network-based development works is as
follows. 
In the "old" days, the computer use to be the computer and in order to
tailor a computer's capabilities for a given application, one would plug
cards into the computer's ISA or PCI buses.  For example, in order to
control a servo motor system, one would plug a servo motor controller
card into a PCI slot and then the computer's operating system would
recognize it and make it available to software applications.

But now, instead of the computer being the computer, the *network* is
the computer and these new network-based computers consist of nodes
connected by wired or wireless network connections.  These networked
nodes can be as close to one another as fractions of a millimeter or as
far apart from one another as the other side of the globe.  In order to
expand the capabilities of a network-based computer, one simply plugs
more nodes into the network.  One way of looking at this is that the
network is the PCI buss for the new class of network-based computers.


JAVA IS AN OPERATING SYSTEM FOR NETWORK-BASED COMPUTERS

Just like Linux and Windows are operating systems for single computers,
Java is an operating system for network-based computers.  As with all
paradigm shifts, this is a difficult thing to see at first but as people
start using these new network-based computers the understanding of them
and their potential will eventually 'sink in'.

Here are some exciting application scenarios that the new network-based
computers have recently enabled:

1)  Secure remote control and monitoring of devices within the home or
business using any PC on the internet or a cell phone.  Service
companies can also be contracted to provide remote in-home services such
as security, appliance monitoring and energy management.

2)  Company-wide automated 6-Sigma data measurement applications which
feed measurement data into the company's enterprise systems.

3)  City-wide air conditioning load management system.

4)  Quick configuration of CIM (Computer Integrated Manufacturing)
workcells for the flexible production of parts.
