1. Introduction:
1.1 Goals
The main business goals which are perused by the uSoft.com organization are discussed in
the below section.
 Protection of various sensitive information within the organization and configuring the list of
access control for handling the access of the user to the servers of different department of
the organization.
 Improvement of the wireless communication and the VoIP among all the departments of the
organization which will improve the performance of the current employees.
 Network scalability improvement of the current network for allowing increased number
users to connect which will help in the growth of the company.
 Configuring the network in such a way that performance will not be decreased with
increased number of users and other different types of risks must be mitigated such as jitter,
packet loss and contestation.
 Configuring the access control list for communication management of the users for accessing
servers of different department of the organization.
 Connecting different subnet wireless access point in such a way that the intruder will be able
to gain local network access.
1.2 Purpose:
The main purpose behind the development of this network is creating a network solution
that will consist a centralized management of data traffic flowing. This data flows from different of
sources to a specific destination address within the network. The successful data sending and data
receiving from the headquarters to the fellow branches of the organization will reduce the network
responding time. The network of the organization must be configured in such a way that the
employees will be connect with the organizational network from remote location. This will surely
improve the productivity of the employees. Also, the network must be configured in such way that
there is no error in the network configuration and no error will be occurring in the future cases.
Besides that user activity monitoring should be done in this type of system to ensure that the
resources are safe. Users can be monitored effectively by implementing a network security policy,
firewall and by implementing a DMZ.
1.3 Background and Scope:
The discussed network solution is in the development process for the uSoft.com
organization which is a private software development organization for biomedical solutions. This
organization is having a HQ which comprises of total 6 different departments in it. The main aim of
the organization behind developing this network solution expanding the organization with meeting
the technical and business goals of the organization. In the present situation the organization is
having total 102 numbers of employees in the department of software development. 92 employees
are working for designing the solution, 52 peoples are in sales department, 22 employees in human
resource department, 32 peoples in the financial department and 62 employees are serving in the
customer support department. The present network setup consists 1 server in each department of
human resource, finance and sales while the solution design department is having 2 severs and the
software development department is having total 3 servers installed the subnet of the network. In
this case some more numbers of IP addresses are kept in the reservation to support expansion
process of the organization that will help more employees to connect to each of the subnet which
are installed in the department of the organization.
