Monday 10/20
-
Due:
Class:
- IP
- 30 min exam. Counts as 1/2 of an exam. Covers chapter 3 and
section 4.1. Emphasis is on chapter 3.
Study Guide is here.

Wednesday 10/22
-
Due:
Class:
- Review Exam
- Important Chapter 4 Coverage Information:
- 4.5: We will cover only the introduction and first paragraph
of sections 4.5.1 and 4.5.2. We will cover the concepts of 4.5.3
(terms: AS, AS routing protocol, gateway routers, and inter-AS routing
protocol.)
- 4.7: Only the terms: Broadcast vs. Multicast and IGMP.
- Routing basics: In this section, we will not cover all the details
of algorithms. You are expected to work through Dijkstra's algorithm
(p 371) and we will have a homework problem on it. You will be
resonsible to know the definitions of these terms:
- Link state vs. Distance Vector algorithms
- What is transmitted between routers in LS and DV algorithms
- DV issues: Bad news travels slowly. Poisoned reverse.
- Autonomous Systems. Distinction in intra-AS routing protocol vs.
inter-AS.
- Basics of RIP and OSPF
- OSPF areas (as distinct from AS's)
- What BGP is for. eBGP vs. iBGP.
- Introduce ICMP Wireshark Lab
- ICANN and IP addresses (See notes).
-
Friday 10/24
-
Due:
- Chapter 4 Review Questions:
R19 (This is really two questions:
what fields have a common function and are they the same length and
coding.)
- Wireshark ICMP lab. Note that while this lab could be done on any machine, you might find some of the mechanics easier on the
TS-111 LINUX machines. The lab requires you to print traces and the output
of the "ping" command which is more awkward in Windows.

Wednesday 10/29
-
Due:
- Wireshark traceroute lab.
- Wireshark DHCP lab.
- Read article on ipv6 and answer these questions:
- Current projections say ipv4 address should last how long?
- Did the tests tend to measure ipv6 native traffic or tunneled?
- What caused the spike in ipv6 traffic?
Was the spike a signifcant proportion of ipv4 traffic?
Class:
- Briefly mention broadcast/multicast. You will be responsible only
for what the terms mean and that there is a protocol called
IGMP used in multi-cast, not for the details.
- Introduce the Link Layer
- Error detection/correction
-
Friday 10/31
-
Due:
- Chapter 4 problems:
R25,
P22. P22b: Using just distance/vector (i.e. number of
hops), will these routes change and if so, what will be the route from x:
x-z, x-s, x-t, x-w, P29, P30 (for P30, don't try to read the details of
BGP in the text - just try to answer based on what makes sense using
a basic understanding of what BGP does. You do need to know that when
going outside an AS, BGP prefers routes which go through the smallest
number of AS's)
Class:
- Review Wireshark labs
- Multi-access - we will cover
the distinction between partioning, random access, carrier-sense
protocols, and taking turns.
- ARP
- Ethernet
-
Monday 11/3
-
Due:
- Chapter 5: R1, R2(For these possible link-layer services, which do
IP or TCP provide: Framing, link-access, reliable delivery, flow control,
error detection, error correction, full duplex.), R3, R4, R7
Class:
- Review homework
- Hubs and switches
- Introduce PPP - we will cover PPP only at a summary level
-
Wednesday 11/5
-
Due:
- Chapter 5: R9, R10, R12, R13, R14, P22 (assume 4 hosts in each of the
3 departments plus the two servers for 14 hosts), P23, P24. For Figure
5.26, remember the round icon is a router and the square ones are
switches.
Class:
- PPP and ATM. ATM: We will cover only the fundamentals, not different
versions of AAL. We will cover what is meant by IP over ATM.
- Introduce Networking lab. Note: This lab
assignment is "under construction."
-
Friday 11/7
-
Due:
- For the networking lab intro, turn in
your definition of a viable subnetting scheme. In class, we will discuss
your solutions and pick the one we will use for the lab. The homework is
in the section of the networking lab
entitled Student Activities in items marked Homework.
Class:
-
- Review networking lab subnetting. Start lab if time.

-
Due:
- Read sections 8.1, 8.3.3 and 8.6.
Class:
- Tour Malone I/T networking facilities. Meet at I/T -
Enter NE corner Haviland - I/T help desk.
-
Wednesday 12/3
-
Due:
- Wireshark 802.11 lab. This lab uses a trace which comes with the text due
to the difficulty of obtaining traces from Wireless cards. The trace can
be obtained from the textbook website as noted in the PDF file or from
R:\erodd/Wireshark_802_11.pcap. When the lab asks for "which frame", it is
best to answer with time-stamp, rather than frame number - this is how
we will reference frames in class.
Note: This lab will not be collected and graded. We will go over
it in class. The quiz on Friday will assume an understanding of this lab.
Class:
- Review wireless Wireshark lab
- Security - Firewalls
- New Experimental alternative to SIRs - It will be helpful if we
everyone there to trial this new instrument.
-
Friday 12/5
-
Due:
Class:
- Major quiz on wireless and SSL and what we learn in
the I/T tour. Counts as 1/2 exam.
Security terms we covered:
- Symmetric key
- public key
- MAC
- Certificate
- Digital Signature
- SSL - where it fits
- SSL flow
- Review quiz
