Virtualized Network Design & Implementation with SDN, NFV, Automation, and Redundancy

Overview

This project involves designing and implementing a virtualized network architecture using Software-Defined Networking (SDN), Network Functions Virtualization (NFV), automation, and redundancy. The goal is to create a scalable, flexible, and fault-tolerant network infrastructure.

Objectives

• Implement SDN for centralized network control.
• Utilize NFV to deploy virtualized services (firewalls, load balancers, VPNs).
• Automate network configuration using Python/Ansible.
• Apply redundancy techniques to ensure high availability.
• Test and validate the network setup for performance and reliability.

Network Design Components

1. SDN (Software-Defined Networking)

• Uses an SDN controller (e.g., OpenDaylight, ONOS) to manage network traffic.
• Separates the control plane from the data plane for better flexibility.

2. NFV (Network Functions Virtualization)

• Deploys virtualized firewalls, VPNs, and load balancers using Docker/KVM.
• Reduces reliance on hardware-based networking devices.

3. Automation

• Uses Python/Ansible to automate:
  • Network provisioning
  • Configuration management
  • Traffic routing

4. Redundancy & High Availability

• Implements failover mechanisms and backup links.
• Uses load balancing to distribute traffic and prevent single points of failure.

Implementation Steps

Step 1: Setup Virtualized Environment

• Use GNS3, EVE-NG, or a cloud platform (AWS, Azure).
• Install Docker/KVM for virtualized services.

Step 2: Configure SDN Controller

• Install OpenDaylight/ONOS.
• Connect network devices to the controller.

Step 3: Deploy NFV Services

• Set up virtual firewalls, VPNs, and routers.
• Ensure traffic policies align with security best practices.

Step 4: Automate Network Configuration

• Write Python/Ansible scripts for:
  • Device configuration
  • Traffic monitoring
  • Network provisioning

Step 5: Test & Validate

• Ping & Traceroute tests for connectivity.
• Failover simulation to check redundancy.
• Performance monitoring using logs & metrics.
