Unlike the other computer
network courses, this course is organized in a top-down manner --
that is, it begins at the application layer and works its way down
toward the physical layer. The top-down approach has several
important benefits. First, it places emphasis on the application
layer, which has been the high "growth area" of computer networking.
Indeed, many of the recent revolutions in computer
networking--including the Web, audio and video streaming, and
content distribution--have taken place at the application layer. An
early emphasis on application-layer issues differs from the
approaches taken in most other courses, which have only a small (or
nonexistent) amount of material on network applications, their
requirements, application-layer paradigms (e.g., client/server), and
the application programming interfaces. Once you understand the
applications, then you understand the network services needed to
support these applications. You can then, in turn, examine the
various ways in which such services might be provided and
implemented in the lower layers.
Because the course has the
Internet focus, it is organized around a five-layer Internet
architecture rather than around more traditional seven-layer OSI
architecture. These five layers consist of the application,
transport, network, link, and physical layer.
You not only see
how popular applications and protocols work, but also learn how easy
it is to create their own network applications and application-level
protocols. By providing socket programming examples in Java, the
central ideas without confusing students with complex code is
highlighted. Undergraduates in computer science and electrical
engineering should not have difficulty following the Java code.
Thus, with the top-down approach, you get early exposure to the
notions of application programming interfaces (APIs), service
models, and protocols--important concepts that resurface in all of
the subsequent layers.
1. distinguish internet, intranet, extranet, the Internet, and grid
2. describe the core and edge of the Internet (4, 5)
3. define and exemplify circuit-switched and packet-switched
networks (2, 3)
4. understand and explain application, transport, network, and link
layer protocols of the Internet (2, 3)
6. compare and contrast TCP/IP and UDP transport protocols (3, 4)
5. write socket-based programs using HTTP, SMPT, and UDP protocols
7. understand multimedia networking and apply RTSP and RTP protocols

||10% (two quizzes: 5 points
||50% (two exams: 25 points
course consists of lectures, quizzes, programming assignments on
computer network, and three exams.
Quizzes will be
held handed out for your practice two-three weeks, just to quickly
Programming Assignments should
be submitted by email: email@example.com before the
date on which it is due. For
late submissions there will be a penalty of 10% for lateness. Late
submissions will not be accepted after the day solutions are made
available to the class. Please work individually on all assignments.
Please study the assignment specifications, code your programs, and
test them independently. Stop by my office if you have difficulty in
understanding the assignment or the course material discussed in the
Exams will be closed-book/notes. Material
from handouts, textbooks and assignments will be included in the
scope of the exams.
The purpose of these
different instruments is to have a positive learning experience,
critical thinking about computer networking issues, and some sound
grasp of fundamentals. If you feel any of these instruments is not
working for any reason, please send me email and I will consider a
change in the format of delivery.
