Design Abnfor A New School Buildingattached Are Three Preliminary Sc

Design a network for a new school building. Attached are three preliminary school blueprints. Each room will only have an instructor computer except for four labeled computer labs with 30 computers each. Create LANs to group the classrooms (determine how many per LAN by distance and location in the building) for all the teacher's computers in the lecture halls/rooms. Each floor should have an MDF (Main Distribution Frame).

The first floor should have one room being used as a server room. What devices do you use? What cabling? What topologies? What other networks would the building connect to?

Put everything in a Word document (drawings, pictures, explanations, etc.). Include the BN (Building Network) design with four computer labs per floor (10 points), MDF closet per floor (5 points), server room on the first floor (5 points), other networks attached to the first floor (5 points), type of cabling (5 points), type of topology (5 points), and a detailed explanation of your design in typed answers (15 points). The goal is to create a comprehensive network design plan, considering practical device placements, cabling choices, and network topology that supports the school's communication and data transmission needs.

Introduction

Designing a network layout for a school involves careful planning to ensure reliable connectivity, scalability, and security. The blueprint includes creating LAN segments, establishing an MDF for each floor, and incorporating essential networking devices such as switches, routers, firewalls, and servers. This paper demonstrates a detailed approach to designing a comprehensive network infrastructure for a multi-floor school building, covering device selection, cabling, topology, and connectivity to external networks.

Understanding the School Layout and Requirements

The school building comprises multiple floors, each containing classrooms, lecture halls, computer labs, and support rooms including an MDF and server room planned on the first floor. The four computer labs with 30 computers each serve as specialized zones requiring high-speed LAN connectivity. The remaining classrooms are equipped with instructor computers, which need to be grouped logically based on location and distance for optimal network performance.

Network Design Strategy

LAN Grouping

LANs are created based on proximity to reduce cable length and improve performance. For example, each floor's classrooms are grouped into LAN segments connected to the MDF. The four computer labs are segmented into separate LANs due to their high device count and unique data demands. Each teacher's computer in lecture rooms is connected to the same LAN segment as the classroom but separated logically within the switch architecture.

Devices Selection

• Switches: Managed switches are installed on each floor's MDF to connect classrooms, labs, and other device clusters.
• Routers: Central router on each MDF handles intra-building routing and connects the building to external networks.
• Firewalls: Located in the MDF or server room for network security and monitoring.
• Servers: Located in a dedicated server room on the first floor, hosting school data, email, and application servers.
• Wireless Access Points (WAPs): Deployed throughout the building for mobile device connectivity.

Cabling Choices

The network employs Category 6 (Cat6) cabling for all wired connections due to its high bandwidth capacity (up to 10 Gbps) and reliability. The cabling runs through cable trays lining the walls, with proper labeling and management for maintenance.

Topology

The network employs a star topology within each LAN to connect endpoints to switches, with the switches interconnected in a hierarchical star pattern towards the MDF. The MDF connects to the external network via a router, creating a hybrid topology suitable for a school environment, ensuring fault isolation and scalability.

External Connectivity

The school's network connects to the internet via an ISP-provided router. Additional connections include secure VPN links for remote access, and possibly a connection to other regional educational networks for resource sharing.

Network Device Layout

The MDF contains core networking devices: a high-capacity switch, a firewall, and the main router. The server room contains servers, backup systems, and redundant network devices for fault tolerance. The computer labs are connected via switches linked to the MDF, while classroom instructor computers connect directly to local switches as appropriate.

Implementation Overview

Each floor’s MDF hosts managed switches linked to the classroom and lab LANs via Cat6 cabling. The core switch in the MDF connects to the main router, which manages routing to external networks and external internet connectivity. Firewalls implement security policies, while the server room hosts critical resources and services. Wireless access points ensure mobility and device flexibility across campus.

Conclusion

This network design effectively supports the school’s operational, educational, and administrative needs. It balances performance, scalability, security, and manageability, providing a robust infrastructure capable of supporting current and future technological integrations.
