Office Network System Design and Implementation

Scenario Description: Office Setup Network:

TechZone Inc., a mid-sized technology firm, requires an upgraded network design to support its growing operations. The main goals are to enhance network performance, improve security, ensure scalability, and provide reliable services to both internal and external users. This document outlines the comprehensive network design incorporating key technologies and protocols.

Assignment Tasks and Deliverables:

1. VLANs (Virtual Local Area Networks): Segment the network to improve security, reduce broadcast traffic, and organize traffic based on departments.
2. EtherChannel: Increase bandwidth and provide redundancy between the switches.
3. OSPF (Open Shortest Path First): Ensure dynamic routing between multiple network segments.
4. DHCP (Dynamic Host Configuration Protocol): Automate IP address assignment and management.
5. NAT (Network Address Translation): Enable internal devices to access the internet securely using a single public IP address.
6. Other Servers: DNS Server- Resolves domain names for internal and external use. File Server- Centralized data storage for employee collaboration. Web Server- Hosts the company’s internal applications and public-facing website. RADIUS Server- Provides centralized authentication for network access control.
7. SSH (Secure Shell): Enable secure remote management of network devices.
8. WLAN (Wireless Local Area Network): Provide wireless connectivity for employees and guests.
9. ISP Routers: Connect the company network to the internet.
