It is interesting to me how most of the topics interrelate one way or another. To me, the end to end argument is also being applied here as well, as the author first describes the importance of flow control, and how not just the end to end flow control mechanisms are required, but also the routing and even at the gateway level, which is the queueing of packages.
The author does a good job explaining the definitions of fair and also fair scheduling. THe goal was to describe a new fair queueing algorithm, and undersatnd the performance of the FQ algorithm, and also to evaluate it by simulating it. The paper also briefly mentions the different abuses that could happen with a poorly designed system, including users spamming packets to block up the receiver's queue, users who spawn processes to eat up bandwidth etc.
All in all, the fair queueing does provide a major role in network congestion, but this paper doesn't mention anything about implementation costs, which from the next paper we infer that it doesn't scale well. Also, it isn't tested on a real network load, the paper even mentions that the tests implemented were limited, so real load testing is definitely needed.
