Paul, Here are the details on that one: This is useful for a target appliance which serves a large number of concurrent sessions with unsolicited data and adjusts the transport windows on a dynamic basis. In particular, inactive sessions (i.e., those which have not issued any SCSI commands for a reasonable time) may have their window reduced to reassign resources to the active sessions. One method is as follows. The target issues an Asynchronous Message - "target requests parameter negotiation" to provoke the initiator into consuming a command. The target responds to the Text request with an empty Text response and repeats the procedure until the window has been reduced to the desired level. If this is considered important ("this is not a problem in practice" opinions are welcome), there are obvious opportunities for improvement.
