Post-Lab Questions
Please enter the answers to these questions into your lab notebook.
1. Up to the point where a router buffer becomes full, which
protocol (Reno or Vegas) has better performance (explain)?
2. Assume that there is no cross traffic on and end-to-end path,
and that the capacity on that path is much greater than a
single end host - which protocol (Reno or Vegas) will get
better performance (explain)?
3. Provide an illustration of the evolution of CWND for Reno and
Vegas on a path that has a capacity that is less than a single
end host.
4. Which will have a bigger impact: implementing a new
congestion control protocol on servers or implementing it on
clients (explain)?
5. How might you infer the size of both the link capacity and
RWND from the performance graphs provided by ethereal?
