Assignment 1

Measure the latency and throughput of TCP and/or UDP (as noted below) across at least three pairs of machines using at least two different networks. For example, two CS servers (like rho and pi), or a CS server to a laptop, wired or wireless, or off-campus. Create a web page with graphs summarizing your results. All messages must use xor encoding of 64bit (8 byte, java "long") values, based on a (possibly random) key, and validated by the receiver. Include the following measurements: For timing, use System.nanoTime (or the closest equivalent if using other languages). Read through the Java networking tutorial. Also see and for some stripped-down examples of using server and client sockets. When using non-CS machines and networks, minimize unnecessary traffic while developing your programs. Beware of firewalls.
