Course contents :
  • Layered architectures: OSI et TCP/IP models.
  • Physical layer: theoretical basis, transmission media, telephone network, modem.
  • Data link layer: error detection and correction, sliding window protocols.
  • Medium access control sublayer: Aloha, Ethernet, Wi-Fi, transparent bridges, switches, virtual LANs (VLAN).
  • Network layer: virtual circuits and datagramme networks, distance vector and link-state routing, hierarchical routing, network interconnection, address mapping, tunneling, fragmentation, IP, ARP, OSPF, BGP.
  • Transport layer: connection-mode service, addressing, connection establishment and release, flow and congestion control, TCP, UDP.
Course objective : At the end of the course students will understand well the principles of computer networks, their layered architectures (OSI model), the fundamental mechanisms governing the protocols in various layers, and some examples of existing networks.
Prerequisites : Two years of bachelor in computer science or equivalent. This prerequisite is mainly justified because there is a substantial network programming project.
Workshops :
  • Problem solutions lessons, same schedule as main lessons.
  • Practical work consisting of the design and development of a small distributed application
Organization : Second term (from February to May), Fridays from 9AM to 1PM
Written notes : Reference book: Andrew S. Tanenbaum. Computer Networks (Fourth Edition). Prentice-Hall, 2003 (ISBN 0-13-038488-7)
Assessment : The evaluation is threefold: the project, a written exam on exercises, and an oral exam on the theory. At the oral exam the student has to expose clearly and in a synthetical way one part of the course, and prove his/her in-depth understanding by answering questions.
