Content and learning outcomes

Course contents

The course consists of lectures that focus on principles and functionality of current and future Internet architectures, as well as assignments that yield practical skills.

Areas covered:

  • What the Internet is and its underlying design principles.
  • Underlying link technologies and how they interact with IP. (Ethernet, PPP, bridging, learning, etc)
  • What protocols are required to allow internetworking (IP, TCP, UDP, ICMP, etc.)
  • Understanding of TCP/IP protocol stack, layering, encapsulation and multiplexing.
  • Concepts of bridging, learning, virtual LANs, and how they relate to routing.
  • IP Addressing, subnetting and control mechanisms.
  • Transport protocols, including UDP and TCP.
  • Details of routing and routing protocols (RIP, OSPF, BGP)
  • Autoconfiguration and name resolution (BOOTP, DHCP, DNS)
  • IP Multicast and multicast routing (IGMP, DVMRP, PIM, etc)
  • Network Mangement, Traffic measurements and analyzing. (eg. SNMP)
  • Network security (IPsec, firewalls, encryption)
  • IP QoS (Traffic Engineering, RSVP, Intserv, Diffserv, etc)
  • Advanced networking (MPLS, VPN, etc)
  • IP mobility (Mobile IP)
  • Router and Network Architectures
  • Standarization work - IETF and RFCs
  • IPv6 and how it differs from IPv4.

Intended learning outcomes

The students will after the course have theoretical knowledge about functionality and principles, as well as practical skills to plan, analyse, implement, and manage Internet based network functions.
