Exercise Sheet 2

Instructions for uploading are the same as for Exercise Sheet 1. If you forgot them, you can read them again here.

Details about the three servers (UDP, TCP, HTTP) for Exercise 4

All three servers are running on our machine vulcano.informatik.uni-freiburg.de (IP address is 132.230.152.135).

The UDP server is running on port 8888 of that machine. You can send it a number and it will then send you back that number of bytes, in packets of 1000 bytes each. (That means you also have to read packets of 1000 bytes each.) The first ten bytes of each packet contain the packet id. That is interesting for checking which packets get lost and in which order packets arrive.

The TCP server is running on port 9999 of that machine. You can send it a request of the form GET /<number of bytes> HTTP/1.1, or you can just use a downloading program like wget or curl and time it.

The HTTP server is running on port 80, as web servers normally do. Just download the file http://vulcano.informatik.uni-freiburg.de/file_100M and measure the time. You can assume that no data gets lost.

For measuring your transfer and error rates, as requested by the exercise, repeat your experiments several times and also at different times, and form the average of these measurements (or report several numbers if you get very different results). You should ask for large amounts of data, like 10 MB or 100 MB.

Your solutions (files can only be read by the uploader and by us)
