Put CSCD 433 - Lab 8 in the subject line

Question 1.
Think about the different Network layers and what you have learned so far about network design. Specifically, the end points vs. the network core for implementing services.
What do the Quality of Service models (QOS) add to the standard model of best effort service? Are they actually being used in 2017?

Question 2.
In class, we discussed congestion control mechanisms at the router in terms of interesting queue management such as Random Early Detection (RED).
RED is supposed to alleviate some problems with TCP as a result of the tail drop router policies. Can you briefly describe them. Can do a Google search for this information.

Question 3.
What is traffic shaping and how is it used in QOS situations? Who is likely to use this technique?
