1) The document describes a "wandering token" approach for coordinating access to shared resources among thousands of agents in a scalable way. 2) A simulation of the approach for a video on demand application showed that it protected the resource from overload while still granting regular access. 3) The wandering token circulates randomly among members, with a randomized timer governing when new tokens are generated to replace lost tokens. This provides a robust, distributed solution to coordinating access.
