4. 4 Introduction EECS 864: Course Information n Student lecture on one (or more) topic(s) n Major semester team design project n Homework: problems will be assigned n One Tests

5. 5 Introduction EECS 864: Grading n Test = 100 points/test n Student lecture(s)= 125 points n Homework = 25 points n Semester Project = 200 points n Class participation= 50 points n Total = 500 points *Subject to modification

6. 6 Introduction EECS 864 Homework Rules n All work containing more than one page must be stapled - no paper clips and no folded corners. In order to facilitate grading of homework problems, homework shall meet the following specifications: 1. Written (single-sided) on 8.5"x11" paper. 2. For text and equations, typewriten or use an HB or No. 2 pencil (or darker), or blue or black ink. (Pencil is preferred.) No other colors please, except in diagrams or graphs. 3. All pages should be numbered i/j in top right hand corner, with your name appearing at the top of each page. It is O.K. to use your initials after the first page. 4. All work must be shown for full grade - be as thorough as possible. 5. Writing should be legible and literate - if the grader cannot read your handwriting,you will receive no credit for the problem.

7. 7 Introduction EECS 864 Homework Fromat 6. Answers are to be boxed and right justified, with the variables, values (if any) and units (if any), included in the box. Right justified means placed on the right side of the page. 7. Leave half an inch between consecutive parts of a question, and draw a line across the page at the end of each complete question. 8. No part of a question should appear in any margin of the paper. 9. Diagrams and graphs should be of a good size (say at least 3x5 sq. inch), and may contain colors. Diagrams and graphs must be titled, labeled, and clearly drawn. Tables should also be titled. 10. Graphs should be scaled (put number on axes), labeled (put names /units on axes), and titled at the bottom of the graph. Any graph which occupies an area of less than 3x5 sq. inch and which is not titled will not be graded. 11. Where possible use conventional units such as bits/sec, Hz and km

9. 9 EECS 864: Grading n Initial grading scale: ä 90 - 100 A ä 80 - 89 B ä 70 - 79 C ä 60 - 69 D

10. 10 Introduction EECS 864: Grading n Only under VERY extreme conditions will make up tests be given. n I MUST be notified BEFORE you miss a test otherwise you WILL get a 0. n No late homework will be accepted.

11. 11 Introduction Some Student Lecture Topics n Algorithms for optical network restoration(Chapter 7) n Algorithms for wavelength rerouting (Chapter 4) n Routing in wavelength conversion networks ( Section 3.4) n Performance of wavelength conversion networks (Section 3.5) n Sparse wavelength conversion networks (Section 3.6) n Placement of wavelength converters (Section 3.7) n Ethernet Passive Optical Networks (PONs) n Traffic Scheduling algorithms for PONs n Restoration in GMPLS n P-cycles for network protection n Algorithms for Traffic Grooming in Optical Networks

12. 12 Introduction Student Lectures n To be done in power point n To include specific examples to illustrate the concepts. n No overview only lectures, must include examples, must go beyond just summarizing a paper/algorithm. n Goal is to educate the class about the topic. n Each student will provide the class with references to their lecture material.
