Each individual proxy per host uses a simple state machine to track the currently usage by that host. This state machine is used to track when a proxy is in use or not, but also for error detection. The proxy always stays in idle state, when there is no activity. There is a write state for when the proxy has been written and contains data that has yet to be written to a resource. There is a read state for when the proxy has read data from a resource and that entire data has not been fully read by the host. When a proxy access completes, final write or final read, then the state will go back to idle. The following sections show the utilization of these states.
