Computer Science 555 - Reading Report #2 -- Fall 2012

Due: Wednesday, October 10, 2012, 11:00 p.m.

Discuss the differences in the requirements for naming systems for a directory service intended for use across a wide area (e.g. consider the domain name system), as compared with the naming requirements for a web server or content management system intended to support collarboative work on a university campus.

• In your discussion, consider how the differences in requirements will affect:
  • Granularity of names
  • Caching of names and placement of caches
  • The use of replication
  • Use of distribution in the naming system
  • Consistency/syncronization requirements and mechanisms
• Note that the questions in this assignment are about naming and implementation of naming systems. We have discussed the relevant issues in our discussion of naming systems and syncronization.
• Note also that in your dicussion of the web server or content management system you might want to highlight the difference between the management of the names of objects in such a system from the management of the content itself.

INSTRUCTION:

The report must be submitted by 11:00 p.m. on October 10th. Students may receive an automatic extension of 48 hours total that may be applied across the four homework assignments (note that you do not get to use this to extend the due date of the research paper). If you turn(ed) in one of your assignment 8 hours late, then you will only have 40 hours remaining in extensions to use on subsequent assignments.

The report should be approximately 3 pages, or roughly 1200 to 1500 words.

GUIDELINE:

This is a lot to cover in so few words - so our advice is to write a first pass at your answer that is longer, and then edit out material that is redundant or not to the point. The use of tables can be very effective in conveying your ideas in a small area, but the tables must be integrated with your textual discussion, and not the only item in your submission.
