Network Design Overview Create a design document outlining

Create a design document outlining how to build remote access for an organization. Then, write a narrative that explains how to design the LAN at the remote site and discusses how it will interconnect through a WAN to an organization's site. Understanding how networks are constructed is an essential skill for anyone administering a network, as is understanding how design affects the reliability of a network, the cost of implementation, and the cost of maintenance. This assessment focuses on creating a usable diagram that could inform the building of remote access. You will consider the details and specifications needed to implement your design plan.

Directions: Create a diagram for ABC Consulting and then explain how to design the LAN at the remote site and discuss how it will interconnect through a WAN to ABC Consulting's site.

Part 1: Diagram - Use Visio to create a diagram for your project. Include the following in your diagram: Display the basic LAN and WAN topology for your remote sites. Display router and switch placement. Display computers and workstations.

Part 2: Written Explanation - After creating your diagram, write the narrative part of the design document. The narrative should do the following: Describe your diagram. Include specifications about the topologies, cabling, routers, and switches. Provide an analysis of your diagram. Explain the role that the devices on your network play in network communication. Support your diagram. Provide reasoning for choosing the switching and routing, transmission media, and topology.

Paper For Above Instructions

The importance of designing a robust networking infrastructure for organizations cannot be understated, especially in the context of enabling remote access. This paper will outline a design document for ABC Consulting, focusing on a robust local area network (LAN) setup at a remote site and its interconnection through a wide area network (WAN) to the main headquarters. This assessment addresses two critical components: the diagram representation of the network architecture and a detailed narrative explanation of that architecture.

Part 1: Diagram for Network Design

For the diagram, using Microsoft Visio will facilitate the clear visualization of the network components. The diagram will include a basic representation of both LAN and WAN topologies and their interactions.

The LAN at the remote site will typically consist of several computers and workstations connected to a local switch. A router will serve as the key device connecting this LAN to the WAN. The WAN aspect connects the remote site to the organization's central site, allowing for data communication across geographic distances.

LAN Topology

The LAN structure at the remote site will utilize an Ethernet topology. This setup is typically star-based, where each workstation connects to a central switch. This centralization simplifies troubleshooting and enhances reliability. The LAN design will also ensure redundancy through the use of multiple switches (if necessary) to avoid single points of failure.

WAN Connection

The WAN connection will be implemented using Virtual Private Network (VPN) technology to ensure encrypted communication between the remote site and the organization's headquarters. This not only secures traffic against eavesdropping but also contributes to compliance with data protection regulations.

Part 2: Written Explanation of Network Design

The diagram’s key components include:

• Devices: The primary devices in this setup are the router and the switch. The switch facilitates local communication between devices within the LAN, managing traffic efficiently and ensuring optimal network performance.
• Cabling: This network will utilize CAT6 Ethernet cabling, which supports gigabit speeds over distances up to 100 meters. This cabling standard is preferable due to its cost-effectiveness and ability to support high throughput for modern applications.
• Topologies: Both star topology in the LAN and a point-to-point topology in the WAN are utilized to provide efficiency in data transmission. Star topology allows for easy management and expansion of the network.

Analysis of the Diagram

The analysis of the diagram indicates a well-structured approach for ABC Consulting’s networking needs. The role of the switch and router in facilitating communication cannot be underestimated. The switch connects devices within the LAN while the router manages traffic between the LAN and WAN, directing packets to their respective destinations.

The choice of using routers for WAN connectivity allows ABC Consulting to reach disparate locations while maintaining network integrity. Additionally, implementing VPN technologies ensures that data remains secure while traversing public networks.

Reasoning for Design Choices

A star topology was chosen due to its resilience and ease of troubleshooting. In the event of a cable failure, only the affected device loses connectivity, whereas other devices remain unaffected. The use of CAT6 cabling ensures support for high-speed internet connections and accommodates future expansions, should the need arise.

Moreover, the implementation of switches within the LAN reduces bandwidth contention and collisions, promoting higher performance during peak usage. By carefully planning the network design, ABC Consulting can ensure reduced costs in maintenance while maximizing reliability and speed.

Conclusion

In summary, the design document for ABC Consulting outlines a robust framework for remote access. By successfully blending LAN and WAN technologies, the organization can achieve secure and efficient communication between its headquarters and any remote sites. Special attention has been given to design topology, device selection, cabling standards, and security measures, ensuring that this network can scale efficiently in response to future growth.
