Research and evaluate various options/methods that can be used for network designing, including their pros and cons. Select the most suitable option for completing the assessment.

Set up a network comprising PCs, routers, switches, and servers, with appropriate configurations. Connect clients and servers on different networks, configure routing using a dynamic protocol, and verify connectivity through pings and traceroute. Use the IP addresses calculated in Assignment 2.

Configure network services on this network, including DHCP for IP assignment, a web server accessible via a specified URL, DNS for resolving domain names, and a firewall rule to block HTTP traffic between a client and the web server while allowing other traffic. Provide evidence with screenshots and detailed command outputs for each activity.

Network design and configuration are fundamental components in establishing efficient and secure communication systems within organizations. Selecting an optimal network design involves understanding various options, assessing their advantages and disadvantages, and aligning them with organizational needs. This paper explores different network design options, conducts practical setup and configuration, and implements network services to demonstrate comprehensive understanding.

Network Design Options and Evaluation

When designing a network, several topologies and methodologies are available, including star, bus, ring, mesh, and hybrid configurations. Each has specific benefits and limitations. For example, the star topology is easy to manage and troubleshoot but relies heavily on a central switch or hub (Oppliger, 2014). Conversely, the mesh topology offers high redundancy but can be complex and costly to implement (Tanenbaum & Wetherall, 2011).

In selecting an appropriate method for the assessment, a hybrid topology combining star and mesh elements might be dual beneficial, providing robustness and ease of management. The use of VLAN segmentation can further enhance security and traffic management (Forouzan & Gilberg, 2012). This approach balances performance, cost, and complexity, ensuring efficient network operation suited for organizational requirements.

Network Setup and Configuration

The network setup involves connecting multiple PCs (clients), switches, routers, and servers. Following the IP addressing plan derived from Assignment 2, each device receives a unique IP address. Routers are configured with dynamic routing protocols, such as OSPF or EIGRP, to enable seamless inter-network communication (Stallings, 2013).

Router interfaces are assigned correct network addresses, and routing protocols are enabled on all routers. Pings are used to test connectivity among devices, including testing that clients can reach their local routers, remote routers, and servers. Traceroute outputs illustrate the path taken by data packets, providing insight into network routing and latency.

For example, a typical ping from a client to the server network might report successful replies across multiple hops, indicating proper routing. Traceroute output reveals each intermediate device and latency times, confirming the network's functionality and topology (Kurose & Ross, 2017).

Implementing Network Services

Dynamic Host Configuration Protocol (DHCP) is configured on designated servers to automate IP address allocation to clients. When PCs connect, they request addresses, which are assigned along with subnet masks, default gateways, and DNS server information. Verification involves checking the client's IP configuration using commands like ipconfig or ifconfig, ensuring accurate network parameter receipt (Rashid & Casey, 2013).

Web servers are installed on designated servers, configured with appropriate services, and assigned static IP addresses. The URL sanchithadesilva.csu.org is mapped to the web server's IP address using DNS configuration. DNS servers are set up to provide forward and reverse resolution, tested by browsing from the client and confirming correct IP mappings.

The firewall is configured to filter traffic, blocking HTTP TCP traffic only between a specific client and the web server while allowing other traffic types. This is achieved through access control lists (ACLs) on the router or dedicated firewall devices. Testing with ping (ICMP) and HTTPS (TCP port 443) confirms that only HTTP traffic is blocked, whereas other protocols remain accessible (Lammle, 2012).

These configurations demonstrate comprehensive network management, from connectivity and routing to service deployment and security enforcement, critical in enterprise network environments.
