This read-create boolean enables or disables Virtual Source/Virtual Destination (VSVD) closed-loop rate control for this ABR connection, where enabling it makes the endpoint act as a Virtual Destination generating its own backward RM-cell feedback rather than relying purely on end-to-end control. An admin enables VSVD when they want closed-loop congestion control segmented at this switch rather than running purely end-to-end across the whole path, which can improve responsiveness on long or multi-segment connections. For example, on an ABR VPL terminating at this switch, the admin would enable this to have the endpoint generate its own RM-cell feedback locally instead of waiting for feedback from a distant endpoint.
