TDTS06	Computer Networks, 6 ECTS credits. /Datornät/ For: BME C COS CS D IT SOC Y
	Prel. scheduled hours: 40 Rec. self-study hours: 120
	Area of Education: Technology Main field of studies: Computer Science, Computer Enginering, Information Technology
	Advancement level (G1, G2, A): G2
	Aim: Protocols: model protocols in the form of a finite state machine (FSM), describe a typical network architecture with the help of layers, and define and use basic, standardized network-architecture related terms Networking basics: explain the different basic types of protocols, communication channels, and network types, where delays can occur in a network, what different types of delay that exist, and perform calculations on transmission and transfer of data Applications: describe the most common application architectures in the Internet, how the most important application layer protocols work in the Internet and what characterizes them, in the form of what services they offer a user and what typical mechanisms that implement the services TCP: describe how TCP's flow control and congestion control works, what the most important timers of TCP are, and specifically explain how the retransmission timer is set up; explain how connection set-up and teardown is done in TCP and show how reliable data transfer is implemented in TCP IP: describe how IP addressing and fragmentation works, exemplify mobile IP, summarize what IPv6 is compared to IPv4; explain what QoS is, why it exists, and how it can be implemented in an IP network Local area networks: analyze the MAC protocol for IEEE 802.3/Ethernet (wired LAN) and perform calculation on it; describe how the MAC protocol for wireless LAN (WLAN) according to the standard IEEE 802.11b works and what typical problems a wireless LAN must handle compared to a wired LAN Routing: use the Bellman-Ford algorithm and Dijkstra's algorithm, respectively, to calculate the "best" path through a network, describe typical problems that can occur when routing with algorithms based on distance vectors and link states, respectively, and also show how routing is implemented on the Internet Network security: exemplify how different types of security services can be implemented in different layers with the help of different standards
	Prerequisites: (valid for students admitted to programmes within which the course is offered) Knowledge of C or C++ are required in order to be able to do the laborations in the course. It is an advantage if the student also has knowledge corresponding to Concurrent Programming and Operating Systems, especially know how to explain the resource conflicts that can occur in a computer program and how to solve them. This knowledge can, however, be acquired while doing the laborations in the course. The student is also assumed to know how to construct and test programs in a Unix/Solaris environment. Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding.
	Supplementary courses: Computer Network Infrastructure and Mobile wireless networks: systems and applications.
	Organisation: The course consists of lectures and laborations.
	Course contents: Protocol terminology, language, and specification. The protocol layering concept. Reference models for network architectures.
