Push Technology

The Push Process

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.

Introduction

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. 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.

Push Server Model

  The most common delivery model is the push server model. This is a turn- key solution that provides a client, a server, and other development tools. Costs associated with the server may include the number of connections and / or the no of packets sent. Branding may or may not be a issue.

Wall Paper And Desktop Replacements

        For some reasons, different push products need to do various things to do the windows desktop. Microsoft is far from immune. In fact, the internet explorer 4.0 includes far reaching changes to the windows user interface itself. But internet explorer 4.0 onscreen channel displays, called desktop components are not two far out of control.

Application protocol

        This refers to the IP protocol family upon which internet is based. The main protocol transports within this family are TCP and UDP. Although TCP is reliable, it is not timely because its main focus is on making sure that packets arrive at their destinations. It may degrade performance to achieve that goal. UDP cares little about reliability and more about moving packets through the network as quickly as possible. The advantage of push vendor developed proprietary protocols is that they allows some key features to be used persistent file transfer, efficient bandwidth utilization techniques, etc – that are much more difficult to implement via HTTP.

Abstract

As the need for internet grows the importance of new information delivery models such as push increases. With staggering volumes of content on the web, users often find it difficult to locate information of interest. In the  traditional web environment, the user has to request for a particular piece of information, which will then be fetched from the internet server on which it resides. The browser will request the server to open a connection with the client and display the contents on your browser. This is called pull environment.

Conclusion

        As the World Wide Web grows in size and complexity the importance of new information delivery models such as push increases. The push delivery model provides an easy way for end-users to get the information they want from internet, and creates a more effective way for content publishers to reach users.
