TCP/IP Course description: this is a classical introductory course on TCP/IP. It covers basic principles of the internetworking, special features of the TCP/IP stack, methods of addressing and routing, including where masks are used. The course studies all main protocols of the transport infrastructure of the IP network (such as TCP, UDP, IP, ICMP, ARP) and application layer protocols that are directly connected to the transport system (DHCP and DNS). A significant part of the course is dedicated to routing protocols RIP, OSPF, BGP. Course(s) to be taken before this course: Introduction to Networking. When this course precedes the Introduction to IP networks course, it is recommended to make an emphasis on those topics that relate to the TCP/IP stack, which corresponds to the following sections of the book: Internet Standardisation in Chapter 4 Network Architecture and Standardization, Internet in Chapter 5 Examples of Networks, Repeated Transmission and Sliding Window in Chapter 6 Network Characteristics. Chapters of the book on which this course can be based: the main material can be found in Chapters 17 – 20. Also, the following chapters are relevant to a various degree to this course: Network management in IP networks and Application of TCP/IP in WANs (Chapter 22) and IPSec Protocol (chapter 24, the Protected Channel Service).
