Optimizing a Data Transfer › Phase 4: Transfer Mechanism Selection › Transfer Resource Utilization

Transfer Resource Utilization

Note the following considerations when choosing transfer mechanisms:

• Broadcast is less resource-intensive than fanout.
• Fanout is less resource-intensive than point-to-point.

For a one-to-many transfer, if the parameters for broadcast are supplied (and if the transfer is not resolved to an existing transfer held in the TOS, by the duplicate transfer resolution process), then broadcast is selected preferentially to fanout, and fanout preferentially to point-to-point. This preferential ordering of protocols is independent of the precedence rules governing parameter value selection.
