	Prel. scheduled hours: 40 Rec. self-study hours: 120
	Area of Education: Technology Subject area: Computer Systems/Computer Engineering/Electrical Engineering
	Advancement level (G1, G2, A): G2
	Aim: After the course the student should know the following: 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 communications modes, communication channels, and network types, where delays can occur in a network, and perform calculations on transmission and delay of data Applications: describe how the most important application layer protocols work on 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 timers TCP has, 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, what typical problems a wireless LAN must handle compared to a wired LAN, and also exemplify what components a wireless LAN can have according to the standard 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 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) Concurrent Programming and Operating Systems: be able to explain the resource conflicts that can occur in a computer program and how to solve them; be able to construct and test programs in a Unix/Solaris environment and specifically know how to do programming assignments in C, C++, or Java. 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.
