Assignment sample solution of NET4002 - Networking and Security

You are tasked with designing a high-performance, secure, and scalable computer network for a global enterprise that must support real-time applications (such as VoIP, video conferencing), cloud-based services, and handle large amounts of data transfer between multiple data centers located across various continents. The enterprise operates in a highly competitive industry, where downtime and service interruptions are unacceptable, and security of confidential data is critical.

Your network design must meet the following requirements:

• Network Architecture: What kind of network architecture would you choose to ensure low latency, scalability, and high availability for the enterprise’s diverse needs? Include considerations for data center interconnectivity, edge computing, and cloud integration.
• Traffic Routing and Load Balancing: How would you manage traffic flow to guarantee minimal latency for real-time applications and efficient data transfer for large-scale workloads? What routing protocols and load-balancing mechanisms would you implement?
• Network Security: How would you ensure the security of sensitive data and communication in transit, especially in a distributed environment? Discuss measures against external threats like DDoS attacks, unauthorized access, and data breaches.
• Fault Tolerance and Disaster Recovery: Given the critical nature of enterprise services, how would you design the network to ensure fault tolerance, resilience, and rapid disaster recovery in the event of failures or network outages?
