Network Layer Design: Key Issues and Challenges
Functions and Challenges
The network layer, or layer 3 of the OSI model, plays a crucial role in computer networks. It handles addressing, routing, and data forwarding, ensuring that data packets reach their intended destinations efficiently.
Design Issues
Network layer design involves addressing various challenges and design issues, including:
- Store-and-forward packet switching
- Addressing and routing algorithms
- Quality of service (QoS) and security
- Network architects and engineers must carefully consider these design issues to craft networks that function reliably, efficiently, and securely.
