The
Occasionally Connected Computing (OCC) Model
This month in 'The Leading Edge' is an introduction to the Occasionally
Connected Computing (OCC) model. You may have already encountered
the Mobility Inflection Pointif not, you soon will. Its
a dramatic change in mainstream technologies and user expectations
based on these three trends:
Motivated by productivity improvement, business users are making
notebook PCs their client systems of choice and they are also beginning
to embrace powerful PDAs and intelligent Web phones
For similar reasons, businesses are piloting and deploying
wireless LANs
No longer tied to their desks, more and more business people
expect to be productive while they are on the go, even if thats
simply going from an office to a conference room
Mobile/wireless
PCs are creating new expectations among business users. They want
to maintain their work sessions without disruption as they move
in and out of subnets and in and out of wireless hot spots. But
service discontinuities mean mobile/wireless PC users have to operate
in an intermittently connected world. Unfortunately, many of todays
applications fail to deliver seamless productivity in such an environment:
thats the challenge and the opportunity presented by the Mobility
Inflection Point.
Applications
today are largely divided across a chasm of local desktop applications
with little reliance on the network for data, and web applications
that are totally dependent on a live network connection. In reality,
people are not living in these connectivity extremes, and typically
have occasional access to the network, particularly with mobile
computers and handheld devices. The existing model for applications
today doesn't represent this usage pattern well, where applications
largely fall into "desktop" or "web" categories.
Applications should be able to more easily live across both of these
worlds, gaining the advantages of network connectivity when it's
available and continuing to function on the local desktop when off-line.
This
is the challenge that companies such as Intel and Macromedia have
decided to address by providing hardware and software tools enabling
us to produce such software. On the communications front, similar
efforts have been made to improve coverage using Wi-Fi technology
across the globe. One particular company in the UK has recently
launched the first of 18 helium-filled balloons flying a mile up
in the air and connected to the ground by fibre-optic cable. Anyone
within a certain radius of these balloons will be able to get internet
access using the appropriate hardware which means you could keep
your laptop connected while traveling.
