- 8. Network Diagrams: Guidelines For each computer , indicate the operating system, as well as the software applications or servers running on it. For each connection among computers, indicate what protocol is used (e.g. RMI?) 1 2 3 Product Management System Chapter 3: Technical Diagrams
- 9. Examples of Network Diagrams 1 2 For computers in the same physical location , group them together using a dotted circle (e.g. “Office”) Indicate Internet using a “cloud” Customer Registration System Chapter 3: Technical Diagrams
- 10. Today’s Exercise: Cheap Air Exercise 3.1 , found in Chapter 3 of your lab workbook. Problem Statement: Your superior approached you to design the network diagram to link CheapAir ’s Call Centre operations with Headquarters. Submission Date: Start of your next DSCN class Chapter 3: Technical Diagrams
- 11. Today’s Exercise: Cheap Air Based on the guideline given to you, also follow closely the “ list of conditions ” (Figure 3-1) given to you with regards to CheapAir . Make assumptions if details are not given (You can use Oracle as a database, or Sun Java Application Server for your server.) Draw the diagram on the blank pages given at the end of Chapter 3; you may also draw a soft copy (using MS Word, etc) and then print it out and put in your lab workbook. Chapter 3: Technical Diagrams
