Assignments for CSE 588
The purpose of the weekly assignments for this course is two-fold; not
only do they serve as a way of reviewing and enhancing the knowledge you
acquired in lecture, they also prepare you for the following lecture.
Assignments are due every Thursday at the beginning of class.
They are to be submitted by paper.
Eastside students may submit late homeworks by email
(in text, HTML, or Postscript format, either embedded
in the document or using a MIME-attachment) to
The first few minutes of each class will be dedicated to discussing the

Homework #3, due April 24th at the beginning of class
- Read this paper (or PDF format).

- Start looking at Chapter 8.
We talked about host configuration in class last night, using RARP,
BOOTP and DHCP. These provide a way for the end-system to get an IP
address. What other configuration info besides an IP address does a host
need in order to function, that is, to send/receive IP packets on the net
and to figure out where to send them? What else needs to happen if the
host is acting as a server (e.g. web or ftp) ?
IPv6 has 128 bit addresses, up from 32 bits in IPv4. How might these
big addresses be used to solve the problem of host autoconfiguration?
(Assume Ethernet-connected hosts.) What implications would such a
strategy have for the Address Resolution Protocol (ARP) ?
- Please submit a detailed outline for paper #1.
Submissions should include both a paper copy at the beginning
of class. Please follow this up with an email
version within 24 hours of class.
Remember to use text/plain or text/html for the version you
send by email
(for one thing, so that we can easily edit out your name!).
Homework #2, due April 17th at noon
- Continue reading chapters 3 and 4; begin reading chapter 5.
- Chapter 3: 21, 22, 23
- Chapter 4: 1, 2
- Chapter 5: 15
- 11111 is 4B/5B's coding for idle. What problems are there with
this scheme? What could be used to fix this problem?
- Some CRC can be used to correct small numbers of errors. Why?
Why do link protocols simply discard frames with incorrect CRCs
rather than attempting correction?
- Why have the powerful error checking (CRC) at the lower layers
and the less powerful checking at the upper layers (Internet
- In FDDI, when a claim frame is received, a station with a TTRT
equal to the claim may or may not replace the claim frame with
its own. Why not pass it on, knowing that its TTRT requirement
has been satisfied?
