For this task we will be using Seattle, and in the first part of this assignment you will familiarize yourself with the Seattle demokit. Once you are comfortable with the demokit, we will run an all-pairs-ping on computers distributed around the world. The goal of running the all-pairs-ping is to observe non-transitive connectivity (when two computers cannot communicate, but they can both communicate with a third computer). Following this, we will set up one-hop detour routing to circumvent non-transitive connectivity to allow the computers to communicate through the intermediate node. The final part of the assignment investigates whether or not a computer is behind a NAT (network address translator) and illustrates the practical issues with communicating with a NATed node.||

 || ClickExampleExperiment || [[Image(ClickExampleExperiment.png, nolink, 50%)]] || This example experiment shows how to use GENI resources to test a simple non-IP routing technique. This experiment will be of interest to experimenters working with novel protocols, particularly those with Click-based implementations.[[br]][[br]]You will use ProtoGENI hosts and Click modular router software to build your network.[[br]][[br]]In order to try this example experiment, you should have GENI credentials and be familiar with using the omni command line tool.
