• Explain network design processes and methodology.
• Create network architecture with specific design objectives.
• Select network components and details to realize the design.
• Assess network performance by applying the correct approaches.
• Demonstrate procedures to obtain meaningful network system requirements.
• Translate network system requirements into quantitative network design parameters.
• Model the proposed network for design creativeness and performance assessment.
• Identify network design for a cellular network that supports both voice and data.
• Apply network security technologies to network design.
• Develop a network design via a class project to utilize knowledge learned from the course.

Textbooks

You are not required to purchase any textbooks for this course. There are readings in every module from a variety of sources, including several textbooks and industry produced references. However, all readings are set up through the Sheridan Library eReserve system and may be accessed electronically by selecting the eReserves link in the course site.

Required Software

Webcam, microphone (if provided with computer, this is usually adequate along with adequate lighting and no background sound interference). Microsoft Office or equivalent software tool required. Software capable of drawing diagrams is required.

Student Coursework Requirements

It is expected that each module will take approximately 10-12 hours per week to complete. Here is an approximate breakdown: reading the assigned sections of the textbook (approximately 4 hours per week), listening to the audio annotated slide presentations (approximately 2 hour per week) as well as the Lightboard Studio demonstrations (approximately 1 hour per week), and working through the homework assignments
(approximately 4-5 hours per week).

This course will consist of four basic student requirements:

1. Discussion board assignments (15% of final grade)

Weekly discussion board assignments require you to think about real-world applications for the network design concepts you will be learning. You are required to respond to each discussion prompt as well as respond to at least two other students’ post.

2. Assignments (Five Total) (25% of final grade)

This course has five weekly “homework” assignments, found in modules 2, 4, 7, 9, and 12. The assignments are problems that you must complete individually and upload your work to Blackboard. You will have two weeks to complete each assignment. Each assignment is worth 5% of your final course grade. Assignments are to be uploaded in PDF format.

3. Midterm Exam (25% of final grade)

The midterm exam is in module 8. You have the entire week to complete the exam. It is an open book exam – to be completed independently. Your exam must be uploaded by the due date as a PDF. Late submissions will be penalized 10% per day.

4. Term Project (35% of final grade)
The term project starts in module 3. It is an individual project requiring you to create a network design. The project will apply network design processes learned in the class. There are project deliverables in modules 4, 7, 13, and 14. A complete description of the term project is posted in Module 3.

Grading Policy

Assignments are due according to the dates posted in the Blackboard course site. Students may check these due dates in the Course Calendar or the Assignments in the corresponding modules. Grades will post no later than one week after assignment due dates. A grade of A indicates achievement of consistent excellence and distinction throughout the course—that is, conspicuous excellence in all aspects of assignments and discussion in every week. A grade of B indicates work that meets all course requirements on a level appropriate for graduate academic work. These criteria apply to both undergraduates and graduate students taking the course.

The following grades are used for this course: A+, A, A– (excellent), B+, B, B– (good), C (unsatisfactory), F (failure), I (incomplete). A grade of F indicates the student’s failure to complete or comprehend the course work.

A course for which an unsatisfactory grade (C or F) has been received may be retaken. The original grade is replaced with an R. If the failed course includes laboratory, both the lecture and laboratory work must be retaken unless the instructor indicates otherwise. A grade of W is issued to those who have dropped the course after the refund period but before the drop deadline. The transcript is part of the student’s permanent record at the university. No grade may be changed except to correct an error, to replace an incomplete with a grade, or to
replace a grade with an R.

The Whiting School assumes that students possess acceptable written command of the English language. It is proper for faculty to consider writing quality when assigning grades.

For incomplete grades, please see the Graduate Programs catalogue for the Whiting School of Engineering.

The course grading scale is the following:
100–98 = A+
97–94 = A
93–90 = A−
89–87 = B+
86–83 = B
82–80 = B−
79–70 = C
<70 = F

Academic Policies

Deadlines for Adding, Dropping and Withdrawing from Courses

Students may add a course up to one week after the start of the term for that particular course. Students may drop courses according to the drop deadlines outlined in the EP academic calendar (https://ep.jhu.edu/student-services/academic-calendar/). Between the 6th week of the class and prior to the final withdrawal deadline, a student may withdraw from a course with a W on their academic record. A record of the course will remain on the academic record with a W appearing in the grade column to indicate that the student registered and withdrew from the course.

Academic Misconduct Policy

All students are required to read, know, and comply with the Johns Hopkins University Krieger School of Arts and Sciences (KSAS) / Whiting School of Engineering (WSE) Procedures for Handling Allegations of Misconduct by Full-Time and Part-Time Graduate Students.

Course Auditing

When a student enrolls in an EP course with “audit” status, the student must reach an understanding with the instructor as to what is required to earn the “audit.” If the student does not meet those expectations, the instructor must notify the EP Registration Team [EP-Registration@exchange.johnshopkins.edu] in order for the student to be retroactively dropped or withdrawn from the course (depending on when the "audit" was requested and in accordance with EP registration deadlines). All lecture content will remain accessible to auditing students, but access to all other course material is left to the discretion of the instructor.
