3.1 DESCRIPTION OF NEW SYSTEM

3.1.1 Narrative

WeTalk Direct Bandwidth Usage Monitor (WeTalk Direct BUM) is a Windows application that

monitors and analyzes the bandwidth usage of the server workstation and client workstations in

WeTalk Direct Incorporateds office network. WeTalk Direct BUM provides information like the

downloads and uploads speed, average download and upload speed, fastest download and upload speed,

displays the IP address of the server workstation and the connected client workstations. WeTalkDirect BUM is simple to use. WeTalk Direct BUM runs and displays a system tray icon and shows a

repositionable window that you can place on your desktop. WeTalk Direct BUM is set to auto run at

system startup. WeTalk Direct BUM has a simple graphical user interface but it is very useful for

the technical staff. WeTalk Direct BUM contains two applications, the server application and the

client application. The server application is installed in the servers workstation while the

client application is installed on the clients workstations.

Using WeTalk Direct BUM is a big help to the technical staff this is because it is easy tocheck the bandwidth usage of the connected clients. The client application will automatically

connect to the server application. With WeTalk Direct BUM, the technical staff can save time and

energy. The technical staff can leave the server workstation without anything to worry about

because with WeTalk Direct BUM running, WeTalk Direct BUM records the bandwidth usage statistics

of the client workstation whenever it connects and or disconnects.

WeTalk Direct BUM also displays the computer information of the server workstation. It

displays the computer name, the current user, the operating system, platform and version of the

operating system, the configured language of the computer, the CPU and RAM usage along with its

progress bar and percentage, and the total and available physical memory of the computer.

5/28

In Figure 3.1.4, it shows that the Client Application installed in the client workstations

connects to the Server Application installed in the server workstation because the Server

Application accepts TCP clients. Then the Server Application converts binary to message, and then

passes the sent messages to the Client Meter Generator Module. The Server Application sends

disconnection message to the Client Application when changing the port for communication and the

Server Application calls the Database Manipulation Module for saving bandwidth usage statistics.

The Server Workstation displays the number of the connected clients and displays the IP address of

the connected clients in a List Box. The Server Workstation removes the Client Meter. The Server

Workstation changes Port for TCP Listener and calls Database Manipulation Module.

Windows XP licensed / Windows 7/ Windows Vista The new current system is design for this

kind of operating system.

.NET Framework 3.5 -builds incrementally on the new features added in .NET Framework 3.0.

For example, feature sets in Windows Workflow Foundation (WF), Windows Communication

Foundation (WCF), Windows Presentation Foundation (WPF) and Windows Card Space. In addition,

.NET Framework 3.5 contains a number of new features in several technology areas which have

been added as new assemblies to avoid breaking changes. They include the following:

Deep integration of Language Integrated Query (LINQ) and data awareness. This new

feature will let you write code written in LINQ-enabled languages to filter, enumerate,and create projections of several types of SQL data, collections, XML, and Datasets by

using the same syntax.

ASP.NET AJAX lets you create more efficient, more interactive and highly-personalized

Web experiences that work across all the most popular browsers.

New Web protocol support for building WCF services including AJAX, JSON, REST, POX,

RSS, ATOM, and several new WS-* standards.

Full tooling support in Visual Studio 2008 for WF, WCF, and WPF, including the new

workflow-enabled services technology.

New classes in .NET Framework 3.5 base class library (BCL) that address many common

customer requests.

When installing the new system it will look for a .NET Framework 3.5 during installation for its

compatibilities to be able to do what it is design for and use for.
