Assignment sample solution of CSE2/4NWT - Networked Systems

You are tasked with designing a networked system for an organization that provides real-time services (e.g., video conferencing, VoIP, live streaming) for clients spread across multiple geographical regions. The system needs to handle a high volume of users while ensuring low-latency communication, high availability, and security. Furthermore, the system must be capable of scaling with increasing demand and be resilient to network failures or outages.

The solution should address the following key requirements:

• Network Architecture: What type of network architecture would you design to support real-time services efficiently, ensuring scalability and low latency for users across multiple regions?
• Traffic Routing and Load Balancing: How would you implement efficient traffic routing and load balancing to minimize latency and ensure reliable performance for real-time services?
• Security: How would you secure the communication between clients and the network infrastructure to prevent unauthorized access, eavesdropping, and other network-based attacks?
• Fault Tolerance and High Availability: What strategies would you use to ensure that the system remains highly available, even in the event of network failures or server outages?
