4.1 Introduction of Network Layer:
This segment introduces the Network Layer, highlighting its critical role in the OSI model. You’ll learn about its purpose in facilitating communication between devices across different networks and ensuring efficient routing of data packets from source to destination.
4.2 Network Layer:
In Network Layer Need, we discuss why the Network Layer is essential for seamless data transmission. Network Layer Service covers the key services it provides, such as logical addressing, routing, and packet forwarding. Network Layer Design Issues explores common design challenges and strategies to overcome them, ensuring robust network architectures.
4.3 Routing Algorithm:
This section covers routing algorithms, starting with Least Cost & Dijkstra’s Algorithm, offering detailed explanations and real-world applications. In Bellman-Ford Algorithm, we discuss the benefits, limitations, and practical uses of the Bellman-Ford algorithm, providing a comprehensive understanding of dynamic routing protocols.
4.4 Hierarchical Routing:
In Broadcast & Multicast Routing, we explain techniques and their importance in large networks. Practical Based on Broadcast & Multicast Routing showcases real-world applications and examples, demonstrating these routing techniques in action to help you apply these concepts practically.
4.5 IP Addresses:
This unit starts with Public and Private IP, explaining their differences, use cases, and importance in network security. Practical Based on Public and Private IP, provides practical examples to illustrate their usage. IPv4 Classes, delves into different IPv4 classes, their structure, and roles. Subnetwork, explains subnetting and its benefits, followed by Practical Based on Subnetwork, offering hands-on subnetting examples. Troubleshooting IP Addressing, explores techniques to resolve common IP addressing issues. Header Format, details the structure and significance of IP headers. Packet Forwarding, covers methods and processes of packet forwarding. Fragmentation and Reassembly, explains fragmentation and how reassembly is achieved, with Numerical Based on Fragmentation and Reassembly, providing numerical problems to solidify your understanding. ICMP, discusses the role and functionalities of the Internet Control Message Protocol in network diagnostics and error reporting.
4.6 Comparative Study of IPv4 and IPv6:
In this final section, we compare IPv4 and IPv6, highlighting their evolution, improvements, and differences. This comparison helps you understand advancements in IP addressing, preparing you for the future of network communications.
