    3030 * Broker. A broker mediates resource discovery and arbitration by controlling the scheduling of resources at one or more substrate providers over time. It may be viewed as a service that runswithin a GENI clearinghouse. A key principle in Orca is that the broker can have specific allocation power delegated to it by one or more substrate authorities, i.e., the substrate providers “promise” to abide by allocation decisions made by the broker with respect to their delegated substrate. This power enables the broker to arbitrate resources and coordinate allocation across multiple substrate providers, as a basis for federation and scheduling of complex slices across multiple substrate aggregates. Brokers exercise this power by issuing tickets that are redeemable for leases.
