The Internet, like the steam engine, is a technological breakthrough that changed the world. – Peter Singer
One of the most important aspects of modern world is the internet – the collection of uncoordinated heterogeneous devices be it computers, phones and other gadgets that exchange data and perform computations. Almost every aspects of modern life is touched by this invention. In this course, we study various aspects like protocols, standards, software etc that make such a huge collection devices work together and achieve various computational tasks.
Learning outcomes
At the end of this course we expect the student to know the details of various protocols, networking technologies and basics of network security.
Syllabus
Goals of networking, well-known applications such as web, e-mail and ftp, need for a layered architecture, OSI and Internet. Host-to-host communication: packet switching; reliable transmission - stop-and-wait, sliding window; logical connections. Multiple co-located hosts: addressing, LAN access methods; CSMA/CD, Ethernet, Token passing, wireless LANs; Simple performance models; WAN access methods - PPP. Remotely located hosts: addressing, interconnection of LANs; repeaters, bridges, routers; ATM cell-switching IP: routing protocols (RIP and OSPF); congestion control concepts and mechanisms (choke packets, leaky bucket); IPv4 End-to-end reliability: the end-to-end argument; protocols - TCP, UDP, RPC; connection establishment, flow control. Applications protocols for email, ftp, web, DNS.
Basics of network security, symmetric and asymmetric key cryptography, key exchange, digital signatures. Some security related protocols, ssh, tls etc.
