Introduction

Welcome to the Network Design guide! Whether you're building a small local network or scaling a global infrastructure, this guide provides essential insights to help you architect reliable, secure, and efficient network systems.

Key Concepts

  • Bandwidth: The capacity of a network to transfer data.
  • Latency: Delay before data transfer begins.
  • Throughput: Actual data transfer rate achieved.
  • Topology: Physical or logical layout of network devices.

📌 Tip: Always prioritize scalability and flexibility when designing a network.

Core Design Principles

  1. Redundancy

    • Ensure failover mechanisms to prevent downtime.
    • Use load balancers (e.g., NGINX) for high availability.

  2. Security

    • Implement firewalls and encryption (e.g., SSL/TLS).
    • Regularly update devices to patch vulnerabilities.

  3. Optimization

    • Use Quality of Service (QoS) to prioritize critical traffic.
    • Monitor network performance with tools like Wireshark).

Common Network Topologies

  • Star Topology 🌟

    • Central hub connected to all devices.
    • Easy to manage and troubleshoot.

  • Mesh Topology 🌍

    • Devices interconnected for redundancy.
    • High reliability but complex to configure.

  • Ring Topology 🔁

    • Devices connected in a circular chain.
    • Data travels in one direction only.

Security Measures

  • Firewalls 🔒
    • Control incoming/outgoing traffic.
  • VPNs 🌐
    • Secure remote access to private networks.
  • IDS/IPS 🛡️
    • Detect and block malicious activities.
