Push technology reverses the Internet's content delivery model.
Before push, content publishers had to reply upon the end-users
own initiative to bring them to a web site or download content.
With push technology the publisher can deliver a content directly
to the users PC, thus substantially improving the likelihood that
the user will view it. Push content can be extremely timely, and
delivered fresh several times a day. Information keeps coming
to user whatever he asked for it or not. The most common analog
for push technology is a TV channel; it keeps sending us stuff
whether we care about it or not.
Push was created
to alleviate two problems facing users of net. The first problem
is information overload. The volume and dynamic nature of content
on the internet is a impediment to users, and has become an ease-of
-use of issue. Without push applications can be tedious, time
consuming, and less than dependable. Users have to manually hunt
down information, search out links, and monitor sites and information
sources. Push applications and technology building blocks narrow
that focus even further and add considerable ease of use. The
second problem is that most end-users are restricted to low bandwidth
internet connections, such as 33.3 kbps modems, thus making it
difficult to receive multimedia content. Push technology provides
means to pre-deliver much larger packages of content.
enables the delivery of multimedia content on the internet through
the use of local storage and transparent content downloads. Like
a faithful delivery agent, push, often referred to as broadcasting,
delivers content directly to user transparently and automatically.
It is one of the internet's most promising technologies.
Already a success, push is being used to pump data in the form
of news, current affairs and sports etc, to many computers connected
to the internet.Updating software is one of the fastest growing
uses of push. It is a new and exciting way to manage software
update and upgrade hassles. Using the internet today without the
aid of a push application can be a tedious, time consuming, and
less than dependable. Computer programming is an inexact art,
and there is a huge need to quickly and easily get bug fixes,
software updates, and even whole new program out to people. Users
have to manually hunt down information, search out links, and
monitor sites and information sources.
2. THE PUSH
For the end
user, the process of receiving push content is quite simple. First,
an individual subscribes to a publisher's site or channel by providing
the content preferences. The subscriber also sets up a schedule
specifying when information should be delivered. Based on the
subscriber's schedule, the PC connects to the internet, and the
client software notifies the publisher's server that the download
can occur. The server collates the content pertaining to the subscriber's
profile and downloads it to the subscriber's machine, after which
the content is available for the subscriber's viewing
enough, from a technical point of view, most push applications
are pull and just appear to be 'push' to the user. In fact, a
more accurate description of this process would be 'automated
The web currently
requires the user to poll sites for new or updated information.
This manual polling and downloading process is referred to as
'pull' technology. From a business point of view, this process
provides little information about user, and even little control
over what information is acquired. It is the user has to keep
track of the location of the information sites, and the user has
to continuously search for informational changes - a very time
consuming process. The 'push' model alleviates much of this tedium.
