Token based networking: Experiment NL-101

This short communication outlines an experiment where tokens, associated with application oriented IP streams, authorize access to an optical lightpath during iGrid 2005. The experiment showed the practical viability of this mechanism to perform access control and resource management within optical networks. The experiment was conducted in collaboration with the Virtual Machine Turntable (NL-103) experiment, which used the mechanism to obtain access to continental and transatlantic optical network segments that connected Virtual Machine sites.
