Web Alerts system mini Project 

Web Alerts system is a windows application that communicates with the web services hosted by particular area like e-learning, stock, weather forecast etc. After minimizing this Web Alerts system application, this will hide from the screen will appear as a Small icon in the system tray of Desktop, by which user can again open this tool. When this application is hidden, it will work silently in the background. At some regular intervals of time, it communicates with web services to find if there is any new alert created. If it finds a new alert, the tool downloads the alerts and pops up a message displaying the alert. This message will include a short description and a URL to click. By clicking the URL, you can directly reach the web page represented by the alert. For example, when a new article is submitted in or when an answer is posted for your question, your Web Alerts system tools will immediately popup alerting you to visit the page. For an applications like e-learning, marketing and Query processing even a web application can be developed for entry and editing and that can be tracked by windows, mobile and other application users thru web services. Extend the Web Alerts system application to register for alerts based on user choice. It is one of the hot requirements for every application today. This is one of the modern requirements for every desktop application today.

Purpose of this Web Alerts system Project

The Aim of the Web Alerts system project is to provide users with the updates in the areas like E-learning, stock, and weather forecast. It communicates with the web services to find if there is any new alert created. If it finds a new alert, the tool downloads the alerts and pops up a message displaying the alert. This message will include a short description and a URL to click. By clicking the URL, you can directly reach the web page represented by the alert. For example, when a new article is submitted in or when an answer is posted for your question, your Web Alerts tools will immediately popup alerting you to visit the page. For an applications like e-learning, marketing and Query processing even a web application can be developed for entry and editing and that can be tracked by windows, mobile and other application users thru web services.

The modules involved are in Web Alerts system Project are :

• Weather Reports
• Checking alert
• Search
• Reports
• E-Learning
• Download
• New alert Notification
• Weather Forecast

Application Independent Caching

As the Internet is growing more and more people are moving out of offices running LAN applications over the WAN. Most of the commonly used applications have not been designed taking slow transport into consideration. Even if the applications are slow transport aware, the client-server components may exchange lot of information to maintain consistency of run time information.

Even if the applications implement compression, the net amount of data transfer over the transport is reduced by some %.

There are some applications which have been designed with low bandwidth requirement; one of such application is SAP. SAP caches all the data locally and transfer only changed data over the transport.

The only way to have the application perform better over WAN is to reduce the amount of data transfer.

Caching is one method to reduce the data flowing over the network. A limited set of protocols have caching inbuilt, like HTTP.

In HTTP protocol, the client browser caches the data and on next request of same page it sends the request along with cached page information to server (Last Modification Time of the Page file). The HTTP server checks if the cached information at the client end has not been outdated. If outdated, new page is pushed to client otherwise “Page Not Modified” message is sent to client browser to use the cached object.

To implement similar Application Independent Caching mechanism for other applications, it will require significant changes in the base protocol of the application.

In this paper we will discuss a method to reduce the traffic for applications using standard protocols without modifying the protocol and the application.

We plan to implement a Application Independent Caching mechanism off the applications. We will implement a cached transport over which a application protocol will run. This is similar to implementing caching in TCP/IP layer.

 Application Independent Caching final year project Idea

We want to avoid sending protocol packets over the network which has earlier been sent on network. Rather than sending the complete packet again over the network, we will notify the other entity using a code about generation of same packet on this end.

This requires us to develop a new transport (over TCP) using client and server side agents.The current solution is for two peer machines talking to each other.

 An Application Independent Caching Client (AICC) agent will be installed on both the machines. AICC agent sits about TCP/IP layer of the OS and monitors all the outgoing and incoming packets. AICC has some significant space reserved for caching on hard-disk. All the packets going out and coming in to this machine are cached on this storage and each packet is assigned a universally unique code. Whenever an application transmits a packet, AICC gets the packets and searches for a similar packet in the cache. If a matching packet is found, AICC increments the cache hit counter for the entry in cache and sends the unique code for the cached entry over the wire. The other peer will receive the code rather than the original packet. Since the packet was already sent over the wire sometime back, the receiving machine already has the packet in its cache. It finds the packet using the unique code and passes on the corresponding cached data to the application.
