DD2392 Protocols and Principles of the Internet 7.5 credits

A continuation course in computer science giving a good insight into and a overview of internet technology and services on Internet.

Course offering missing for current semester as well as for previous and coming semesters
Headings with content from the Course syllabus DD2392 (Autumn 2009–) are denoted with an asterisk ( )

Content and learning outcomes

Course contents

Overview of the TCP/IP and OSI models, adressing, local and wide-area networks, routing protocols, transport protocols (TCP/UDP), switched and routed networks, name lookup, IPv6, network security and address translation. The course contains several guest lecturers and a thorough lab course.

Labs: TCP/IP, DNS, SMTP, HTTP, FTP, Routing

Intended learning outcomes

After the course, the student should be able to:

  • generally describe the architecture of the Internet, its services and protocols, including the administration and organization of global Internet resources, such as domain names, IP addresses and Internet standards.
  • in technical detail explain the central protocols that constitute the Internet, including IP, UDP, TCP, ARP, ICMP, SNMP, DNS and SMTP.
  • describe abstractions and principles for network design, including layering, the end-to-end principle, the hourglass model, encapsulation and multiplexing.
  • describe how the procotols are implemented in end systems and routers. Explain how packet forwarding is acheived in a router, including routing, forwarding and error handling.
  • assess different methods for naming, addressing, routing and error detection and how they are used in bridged and routed networks.
  • in detail explain how reliability is provided by the Internet transport protocols such as TCP and SCTP. Describe algorithms for connection control, flow control, congestion control and error handling. The student should also be able to describe the protocol behaviour by studying a packet trace.
  • in detail describe how name lookup on the Internet works and be able to configure a simple name server.
  • describe security aspects within networking and how firewalls and address translation works and why they are necessary.
  • on a general level describe how routing works internally, and between, autonmous systems, as well as explain how they most common VPN technologies work.

Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale

A, B, C, D, E, FX, F


  • LAB2 - Laboratory Work, 3.0 credits, grading scale: P, F
  • TEN2 - Examination, 4.5 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

In this course all the regulations of the code of honor at the School of Computer science and Communication apply, see:

Other requirements for final grade

Written examination (TEN1; 3 university credits).
Laboratory assignments (LAB1; 3 university credits).
Home assignments (HEM1; 1,5 university credits).

Opportunity to complete the requirements via supplementary examination
