What This Document Is
This is a focused exploration of routing principles within communication networks, specifically examining how data packets are directed within a single network – a concept known as intra-domain routing. It delves into the foundational concepts underpinning network organization and the protocols that govern efficient data transfer. This material is part of the Introduction to Communication Networks (ELENG 122) course at the University of California, Berkeley.
