Due: M Apr 2 In class

Each person in class should work individually on this project.
1. Complete sections I - VI of the NS Tutorial

2. In the figure below, A, B, and C send large streams of data to D using TCP. Each node is much faster than the network it is attached to and sends as fast as it can. (a) What is the steady-state bandwidth realized by each stream node? (b) Quantify the variability of bandwidth over different timescales by plotting a graph that has a time interval on the x axis and the minimum, 10%-tile, median, 90%-tile, and maximum bandwidth achieved over an interval of the specified length.

3. Extra credit.
