Syllabus
The course will be done on two parallel tracks. One track will introduce IP, IP level networking, LAN and data communication issues in common communication media. The second track will be related to how a network and some network applications are configured and managed. The second track will be closely tied with practice problems and sessions. By the end of the course, the practical sessions will enable the students to set up a wireless access network with necessary gateway systems and establish a basic functional application over the same.
The broad topics that will be covered are:
Overview of IP (Internet Protocol) and Packet Routing in Internet
Introduction to packet communications and packet switching. Overview of Internet organizations from network perspective. Examples of packet switches: the Bridge and the Router. Typical packet structures at MAC level and IP level. Structure of the IP Datagram as per IPv4 and IPv6. (Course will assume IPv4 in all subsequent parts with some references to IPv6 as deemed fit).
Functional model of Internet as an IP packet switching network. Routing of IP Packets. Common Routing Algorithms. IP Protocol support for Routing. Functions of an IP Router. Internet addressing, address classes, subnets, subnet masks and private IP networks. Address registration in Internet. Address discovery and Route discovery.
Issues in IP packet routing. Fragmentation and reassembly of IP packets. Potential network problems, hazards and how they are avoided. Internetworking. Differences between Bridge and Router.
Overview of LANs over different communication media
The interface between IP and LAN. Common LANs, their MAC protocols and physical layers. Nature of different communication media. Some details on Fast Ethernet and wireless networks. Network hubs and switches.
TCP, Host-network integration, Applications-level Networks
Introducing the TCP and UDP. What are domain names and http. Domain name registration and DNS. Mapping of names with IP addresses. Common TCP services: Introducing Telnet, FTP, SMTP. Port numbers. Proxy systems and Firewalls. DMZ and Gateway-Systems. Role of application-specific gateways
