Network Design
Scenario
The Corporation Techs’ current network
consists of 1 web server (accessible by the public), 2 application servers, 2
database servers, 2 file and print servers, and 50 workstations. The web server
runs Linux/Apache, the other servers run Microsoft Windows Server, and the
workstations run Microsoft Windows. The network is connected through a series
of switches, is not physically connected to other networks, and runs Internet
Protocol version 4 (IPv4). The network is protected by a single border
firewall. The senior network architect, whom you work for directly, has verified
the company’s business goals and has determined the features and functions
required to meet those goals.
The senior network architect
has asked you to create a network design that includes the following components:
§ Current infrastructure elements
§ A logical topology that separates the Accounting and Sales
departments
§ Redundant communications
§ Justification for continuing with IPv4 or upgrading to IPv6
Tasks
For this part of the
project, perform the following tasks:
1. Conduct research to determine the best network design to ensure
security of internal access while retaining public website availability.
2. Design a network configuration with physical and logical topologies.
Identify major network elements (e.g., servers, switches, gateways) and their
locations within the private and protected network segments.
3. Include a high-level plan that ensures communications are available
24/7.
4. Recommend whether to continue using IPv4 or upgrade to IPv6, and explain
why.
5. Create a basic network diagram that illustrates the current network
and enhancements. Include a few workstations to represent all workstations on
the internal network. The diagram will be very high level at this stage and
include only necessary details. You may use a software tool or simply pencil
and paper. You will update this design later in the project.
6. Create a draft report detailing all information as supportive
documentation.
7. Cite sources, where appropriate.
