Network Layer Complete Crash Course Part 1| Routing Algorithms, IP Addressing, IPv4 vs IPv6

Описание: Welcome to the ultimate 3 hour 30 minute Network Layer Crash Course, covering everything from routing and forwarding to IP addressing and security — complete with free notes for easy revision 📘

This is Part 1 of the Network Layer Series, where you will learn how data moves intelligently across networks using logical addressing, efficient routing algorithms, and modern protocols.

🧠 What You’ll Learn
⚙️ Core Responsibilities of the Network Layer

Logical Addressing — how devices are uniquely identified across networks

Routing & Forwarding — how packets find the best path to their destination

Fragmentation & Reassembly — managing packet sizes across different networks

Internetworking & Traffic Control — keeping data flow stable and efficient

🛰️ Routing Algorithms

Distance Vector Routing – RIP protocol basics

Link State Routing – OSPF and Dijkstra’s algorithm

Path Vector Routing – BGP for inter-domain communication

Hybrid Routing – EIGRP combining speed and accuracy
