Transfers in discreet mode are called discreet transfers. Discreet transfers are sent or received in the background when the sending and receiving computers are not heavily loaded. Based on the load, the DTS agent determines when to send the transfer and calculates the optimal transfer rate, so that the discreet transfer has minimal impact on the computer performance and the user productivity.
Discreet mode optimizes performance while minimizing load on the computers participating in the transfer. Therefore, discreet transfers are most often performed at a slower rate than in normal mode. Discreet transfers are recommended for transfers that have a lower priority than normal transfers.
The rate at which a discreet transfer progresses is determined automatically and dynamically by the DTS agent. The DTS agent monitors the load (both CPU usage and the machine network usage) on the sending and receiving computers. When a computer is loaded lightly, the DTS agent uses the spare resources available. However, if the load increases, the agent relinquishes resources, giving priority to other tasks being performed on the computer. In this way, discreet mode optimizes computer performance while transfers are being performed.
Restrictions
Discreet mode is not supported in Data Transport Service r1 and r1.1, Service Pack 1. For all transfers, any discreet mode specifications are ignored if either the initiating or responding DTS agent is running an earlier version of Data Transport Service that does not support discreet mode. Such transfers are successful, but are sent and received in normal mode.
Discreet mode applies only to point-to-point transfers; it does not apply to broadcasts, multicasts, or fanouts.
