Course
Description:
A study of various protocols and technologies and how they are used
in data communications on the Internet.
Learning
Outcomes
Upon successful completion of this course, the student will gain an
understanding of the TCP/IP protocol suite and how it is are used in
data communications on the Internet. The student will gain the
following understanding: RFC’s; the importance of standards;
underlying network technologies; OSI reference model & protocol
layering, TCP/IP reference model, Internet addressing (classful and
classless), subnetting, supernetting, variable-length, ARP; RARP;
BOOTP; DHCP; DNS, IP; ICMP; router functionality, dynamic versus
static routing, routing tables, unicast routing (RIP, BGP, OSPF),
routing algorithms (link state, distance vector), a multicast routing
algorithm (path vector), multicast routing protocols (MOSPF, DVMRP,
CBT, PIM), MBONE, IGMP, End-to-end datagram delivery, Flow
control, UDP and TCP, Private Networks, Virtual Networks, NAT
(address translation), Next Generation IP (IPv6, ICMPv6), Intranet,
Extranet, VPN Technology, Privacy, IP Level Security, and IPSec

will curve GRADES if the SCORE AVERAGE is lower than 70 (curving vs bellcurve approach, TCP/IP new topic) (give example of curving concept – next bullet)
•
No make-up exams – final will count for missed exam – can miss only 1 exam

Explanation for curving
• KSU’s Flexible Major-Choice Approach – No College Major
Entrance Exams
• Explain why we shouldn’t use traditional 10-point grading
approach for CS in “force-fitting” grades and “under-estimating”

ABET Accreditation
Heterogeneous student make up (vs homogeneous)
Gurus in class ?
Should we “Partially” or “Fully” cover the topic ? - which approach
is better for your in the long-range ?
– A more demanding subject matter compared to some others?
• Should the SD be dictated or flexible ?
• Should the Avg be dictated or flexible ?
• Students need not perceive the SCORE as their GRADE – but if
they insist on doing so , think of the exam SCORE as an
NATIONAL GRADE

Constructive Class Participation Grade
Purpose of class participation grade
No 2 students learn the same – No 2 Profs teach the same (or have the same
expectations) – class participation helps the Prof gauge and it also helps
other students – so important you get a grade for it
This grade comes from my personal perception and judgment. Here is my personal
guideline though:
8-6 very impressive student that made exceptional class contribution through out the course - all
questions were of significance - consistent and very constructive
5-4 Good class contribution (somewhat consistent to sporadic)
3-2 Occasional contribution
1-0 Didn't participate (or very negative and disruptive when they participated)
Note 1: Also, I look at positive and not-so-positive contributions balancing themselves out
Note 2: I don't count the cases when students simply respond to my questioning of them - that is my
attempt to create an environment where students feel comfortable to ask questions.
Note 3: I MORESO pay attention to quality and frequency of participation and NOT just frequency

Where do we stand PRIOR to taking CS4500 ??
This Class’s Background (Spring 13)
•
•
•
•
•
•
•
11 CS students (52%), 10 CS-Interest (48%) – Btw, why ?
Average GPA = 2.32 (low C)
Percent GPA less than 2.0 = 23%
Percent GPA 3.5 or greater = 14%
Percentage that made an “A” in 3530 the first time = 16%
Percentage that made an “A” in 3510 the first time = 8%
Percentage of students that either withdrew, fail or made a D grade
in 3530 = 11%
• Percentage of students that either withdrew, fail or made a D grade
in 3510 = 17%
• Percentage of students that either withdrew, fail or made a D grade
in 4500 (retaking 4500) = 8%
Gaining a good understanding of our background as it relates to CS4500
will help us better focus our efforts and be more successful in the course –

General Policies and Expectations:

•
Attendance at all classes is highly encouraged but NOT required. Concepts and
ideas discussed in one class are used as building blocks for more concepts and
ideas in the next class.
Any class session missed by the student is the student's responsibility to make up.
Makeup exams will NOT be given; instead, the last exam will count in place of
the missed exam.
Exams should be returned to the Professor in class right after the review for the
student to receive a grade. Grades are not logged until the students have reviewed
the exams for grading mistakes. If a student takes the exam from the classroom, a
grading penalty of 30-50% will be used due to the fact the Professor has no real
way of determining if the exam was tampered with or not.
Project assignments MUST be turned in on time to receive full credit. Late
project assignments will be graded severely – for each day the assignment is late,
the assignment’s grade will be reduced by 20%.
Students will not be allowed to makeup missed project assignments.
It’s hard to teach a subject like TCP/IP from a single source. The Professor will
use multiple sources to teach various concepts – multiple sources such as (1) text
book, (2) lecture notes, (3) handouts, (4) URL’s, and (5) project assignments.
Every topic detail WILL NOT necessarily be found in the our text.
Students are expected to read the text and any other supporting documentation the
Professor distributes.

In being successful in this subject, expect a minimum of 2-3 hours of study per
hour of lecture (6-9 hours per week)
The Professor expects students to take advantage of office hours when needing
clarification or help.
Purpose of class participation grade – no 2 students learn the same – no 2 Profs
teach the same (or have the same expectations) – I feel constructive class
participation is very important
The Professor greatly supports students sending emails at any time – it will be the
goal of the Professor to reply to emails within a 24-hour time span (not counting
weekends).
Be sure and provide the Professor a functioning personal email address for you
(on your Sign-up List) – already has KSU address
Lecture notes purpose: serve as a guide to the Professor – help organize and time
lecture
Guarantee: current lecture notes will be posted before the next up-and-coming
lecture (ie. lecture notes 1 will be posted before lecture 2 occurs)
See syllabus for withdrawal policy, enrollment policy, and the Academic Integrity
Statement. Be sure and give me the signed copy at the next class meeting
