6-DoS (6 Degrees of Separation) is a 3-5 minute networking activity intended to help you experience and understand the processes by which people send messages to those with whom they are indirectly connected through their direct contacts. It provides participants experiential learning on the consequences of network awareness on information seeking and dissemination.

6-DoS has been built to be used in the form of a game. An administrator sets up the initial parameters of the session (game), such as the number of strong and weak contacts that the participants can choose. The participants choose their strong and weak contacts from within the group participating in the session. Each participant is then assigned a random “destination.” The participants are asked to send a message through one of their contacts such that it finally reaches the destination, while also forwarding any messages that they receive, such that each message reaches its own destination.

After the session, the participants are ranked based on the accuracy of their decisions in choosing the recipients of their messages from their contacts, and some key statistical measures of the participant network and the message flow are displayed. The session can be repeated with different parameters and the results compared.

Link to the software HERE. You will need to obtain a session key from the Administrator to participate in the session.

For the Administrator (who wants to run a session and needs a session key), please watch the 6-DoS admin video (below). The video tells you how to set up a session and generate a session key, which is required your participants to join your session.
