See the chapter numbers for Comer (6th Edition) in the slide sets.

Introduction

Course Book and other reading material:
- Comer (5th Edition):
  Ch. 1 Introduction and Overview,
  Ch. 3 Internetworking Concept and Architectural Model,
  Ch. 10 Protocol layering

IP protocol, ARP, ICMP, DHCP

Content: IPv4 (RFC 791), ARP, ICMP (RFC 792), Path MTU Discovery (RFC 1191), DHCP (RFC 2131, RFC 2132)
Course Book and other reading material:
- Comer (5th Edition):
  Ch. 4 Classful Internet Addresses,
  Ch. 5 Mapping Internet Addresses To Physical Addresses (ARP),
  Ch. 6 Internet Protocol: Connectionless Datagram Delivery (IPv4),
  Ch. 7 Internet Protocol: Forwarding IP Datagrams,
  Ch. 8 Internet Protocol: Error and Control Messages (ICMP),
  Ch. 22 Bootstrap And Autoconfiguration (DHCP);
  RFC 1191
  The course book covers the area sufficiently but the discussion on Path MTU Discovery is (nearly) missing (RFC 1191 covers it)
- Optional material:
  How to work with IP addresses: some useful information can be found here

TCP protocol, congestion control and performance

Content: TCP basics (RFC 793), TCP MSS (RFC 793), RTO calculation (RFC 6298), TCP Congestion Control (Reno) (RFC 5681), NewReno (RFC 6582 [or 3782]), TCP SACK (RFC 2018, RFC 6675), Limited Transmit (RFC 3042), Larger Initial Window (RFC 3390), window scaling, timestamp (RFC 1323), Active Queue Management (RFC 2309), RED ( RED paper), ECN (RFC 3168)
Course Book and other reading material:
- Comer (5th Edition): Ch 12 Reliable Stream Transport Service (TCP):
  Reliable Transport and TCP basics (Ch. 12.1-11),
  TCP details (Ch. 12.12-18, 12.24-33),
  TCP Congestion Control (Ch. 12.19-23);
  RFC 5681, RFC 6582 [or 3782], RFC 6675, RFC 3042, RFC 3390, RFC 3168, and RED paper to the extent that one understands the operational principles. E.g., for TCP SACK (RFC 6675) it should be good enough to read Sections 1-5 (pp. 1-10) and for ECN (RFC 3168) Sections 1, 4-5.0, 6.0-6.1.1.0, 6.1.2-6.1.3 (pp. 3-4, 6-10, 12-15, 18-20)
  The course book discusses the TCP basics and Congestion Control but is not very clear in part nor detailed enough, and the state-of-the-art congestion control mechanisms are discussed only briefly (e.g., NewReno Recovery, SACK Recovery, ECN) or not at all (e.g., Limited Transmit, Larger Initial Window). Also the need for Active Queue Management and RED as one of the widely used implementations of AQM are only briefly discussed. For full information on these refer to the corresponding RFCs and the RED paper (see above). For NewReno, the previous version of the RFC [RFC 3782] might be easier to follow than the current version [RFC 6582].
- Optional material:
  The Kurose&Ross book discusses mainly the basics but not much of the state-of-the art congestion control mechanisms that are best available in the corresponding RFCs (see above).

CIDR, NA(P)T, IPv6

Asiasisältö / Content: CIDR, NAT (RFC 3022), IPv6 (RFC 2460), ICMP6v (RFC 4443), IPv6 Autogonfiguration (RFC 4862)
Course Book and other reading material:
- Comer (5th Edition):
  Ch. 9 Classless and Subnet Address Extensions,
  Ch. 19 Private Network Interconnection,
  Ch. 31 A Next generation IP (IPv6),
  Ch. 30.1-11 IPsec
  RFC 4862 IPv6 Stateless Address Autogonfiguration
  The Comer book has decent discussion on the basics but IPv6 autoconfiguration is covered very briefly, but this information is available in RFC 4862.
- Optional material:
  The Kurose&Ross book discusses the basics but some issues only very briefly Again these are better available in the corresponding RFCs (see above).

Internet routing: RIP, OSPF, BGP

Content: Routing basics, Autonomous Systems, Intra and Inter AS Routing (IGP, EGP), Hierarchical Routing, Internet Routing and Routing protocols: RIP-1 and RIP-2 (RFC 1058, RFC 2453), OSPF (RFC 2328), BGP (RFC 4271)
Course Book and other reading material:
- Comer (5th Edition):
  Ch. 13 Routing Architecture,
  Ch. 14 Routing Between Peers,
  Ch. 15 Routing Within An Autonomous System;
  RFC 2328, Sections 2, 3 and 4, pp. 13-47.
  The Comer book has decent discussion on the basics but it contains some unclear text and errors (e.g., description of RIP-2 Next Hop field usage (see correct explanation in Sec. 4.4 of RFC 2453 for RIPv2) and RIP-2 is covered quite briefly. In addition, partitioning an AS into areas, OSPF support for hierarchy within an AS (OSPF Areas) as well as description of different link state advertisement (LSA) types are not covered. Discussion on the missing OSPF features is avaiable in RFC 2328, Sections 2, 3 and 4, pp. 13-47.
- Optinal material:
  Includes a brief description on OSPF areas. The discussion on Internet routing protocols is more accurate in the corresponding RFCs (see above).

Multicasting and Multicast routing

Content: Broadcast and Multicast Routing Algorithms, IGMP (RFC 3376, [RFC 2236]), Overview of the Internet Multicast Routing protocols: DVMRP (RFC 1075), MOSFP (RFC 1584), CBT (RFC 2201, RFC 2189), PIM (RFC 4601, RFC 3973)
Course Book and other reading material:
- Comer (5th Edition):
  Ch. 16 Internet Multicasting
  The Comer book has decent discussion on the basics though overview on the various Internet multicast protocols is very brief.
- Optional material:

Mobility, Mobile IP

Content: Mobility, Mobile IP (RFC 5944), Mobile IPv6 (RFC 6275)

Comer (5th Edition):
Ch. 18 Mobile IP
The Comer book has decent discussion on the basics though Mobile IPv6 is missing in 5th ed. (6th ed. has a bit more).
Optional material:

Multimedia Networking support in the Internet and Internet QoS

Content: Introduction to Multimedia Networking principles and requirements, RTP (RFC3550), RTCP (RFC3550), RTSP (RFC 2326), SIP (RFC 3261), Scheduling and Policing, Intserv (RFC 1633), RSVP (RFC 2205), Diffserv (RFC 2475, 3260)
Course Book and other reading material:
- Comer (5th Edition):
  Ch. 28 Voice and Video Over IP (RTP, RSVP, QoQ)
  The Comer book has quite short discussion on the topics but no additional material is required on this course. RTSP overview is missing but can be find in the Kurose&Rose book, for example. Comer book (5th ed.) is a bit unclear on RSVP protocol resource reservations. The actual resource reservation is executed with the RESV message, not with PATH message.
