CENG 564/463 Network Programming

This course teaches how to design and implement network programs, protocols and systems in a distributed environment under TCP/IP using the Java programming language. The course tries to give some hands-on experience as well as some theoretical background. We will use the Internet and the Web as our test beds, and Java as our programming language.

The following topics are presented in the course: Communication models of network programs, concurrency and concurrent programming, patterns for concurrent and networked objects, Java I/O streams, Java net package and introduction to network programming with high level classes, TCP socket programming, UDP socket programming, multicast communication model and multicast sockets, accessing network databases with JDBC, distributed applications with RMI, Java web programming, servlets, JSP, Java based wireless applications development and J2ME, security in network applications and introduction to EJB.

The course will involve programming assignments, one midterm, a project, and a final exam. All programming is in Java. Students will conduct and present in-depth programming assignments and a project using distributed and concurrent software design techniques (design patterns), contemporary software development processes (like XP), tools (Together 6.1, JBuilder 9, MySQL, ...) , notations (like UML).

Prerequisites

CENG 564/463 is an advanced undergraduate course and also is a graduate course. We will be covering topics from a number of other courses: CENG 102 Computer Programming (Java programming language), CENG 362 Computer Networks, CENG 217 Object Oriented Programming, CENG 341 Operating Systems and CENG 302 Software Engineering. You will be required to understand a lot of diverse material and apply it in network programs. It also does require a high level of Java programming skills.

Textbooks

There is no single textbook that adequately covers such a diverse range of topics that are taught in this course. Buying multiple textbooks is clearly not very appealing financially. I therefore will try to prepare my own lecture handouts and slides available as course notes and they will be available at the photocopy center or on the web site of the course. Here are some textbooks that are helpful for various parts of the course:

Grading (tentative)

15 % : Homework Assignments
30 % : Project
25 % : Midterm (near the middle of the course)
30 % : Final Exam (a comprehensive exam at the end of the course)

Homework: There will be homework in every 2 or 3 weeks. The purpose of the homework is to give you a chance to exercise the knowledge gained from the recent class material.

Attendance: Attendance is important in order to learn the topics in a timely manner. Attendance will be forced by taking attendance and by making quizzes at random times.

Quizzes: There will be short quizzes at random times. We may not inform you about the quizzes. A quiz may be done at any time during a lecture period.

Project: The project is very important for a course of this kind.

Midterm Exam: There will be one midterm exam that will be given around the mid of the semester.

Final Exam: There will be one final exam that will be given during final exams period of the semester.

Academic Integrity

We will be very careful in grading the projects, homeworks, exams so that everybody gets the grade that he/she deserves. Copying will not be tolerated and will be checked and punished rigorously.

The Fatih University has a very strict policy on academic dishonesty. All work on homeworks and examinations must be strictly individual. Violations of this policy will result in an F grade for the class and may result in suspension/expulsion from the university.
