Lecture 1: Basic switching concepts circuit switching message switching packet >Overhead for every considered protocol: (for voice: 20 bytes. IP, 8 bytes Lecture Notes for the course "Data Networks" by Malathi Veeraraghavan concepts of ARP here in EE136 - just teach basic MAC concepts and link to packet switching; Week 5/6 - MAC protocols. Talk 1: PDF with real audio files. Lecture 1: Basic switching concepts circuit switching message switching packet >Overhead for every considered protocol: (for voice: 20 bytes. IP, 8 bytes Computer, terminal, phone, etc. • A collection of nodes and connections is a communications network. • Data is routed by being switched from node to node This lecture discusses different ways of interconnecting links (of the same kind) to build a simple computer network. To achieve this task, we will use a device packet switching digital networking communications method that groups all transmitted data regardless of content, type, or structure into suitably sized blocks. Based on Chapter 3, Peterson & Davie, Computer Networks: A Systems Approach protocol. Lecture - Packet Switching. 9. Typical Switch. (Fig 3.1). A switch.
