Advanced Network Technologies and Services Laboratory

Networking (Business Data Communication) 2019

This course provides an introduction to fundamental concepts in the design and implementation of computer communication networks, their protocols, and applications. Topics to be covered include layered network architecture, physical layer, and data link protocols, network and transport protocols, routing protocols, and applications. Examples will be drawn from the Internet TCP/IP protocol suite. The course also includes two programming assignments, in which students gain hands-on experience with basic network programming and development of simple network applications.

Announcements (Fall 2019)

Due to the limited seats and TA workload, we cannot afford too many students in both classes. However, it is possible for students to switch between 306007001 and 306007011. Overall, we can only accept around 86 students. The priority would be junior/senior MIS students, MIS graduate students, and MIS double major students.
On the average, we will have weekly homework (including textbook homework, lab assignment, and term assignment). It is difficult to manage multiple heavy-load courses so please seriously considering not taking this course.

Homework

You must submit your homework via the homework submission system (http://hsiaom.nccu.edu.tw:8888/index/ ) before due date/time. Late submission is NOT allowed unless reasonable excuses are emailed to the TA/lecture when homework is announced.
ONLY Portable Document Format (PDF) is allowed in the system; homework in any other format (which may increase TA's load) will be pending (possibly forever).
ID and password will be given in the class. Each student has an individual account in the system. Giving your password to your classmate is considered as cheating.
