Status-Resource

The Status-Resource message is used to provide a simple flow control mechanism between the local node and the application to prevent the application from exhausting its resources. It flows from the application to the node, and is used with a PLU connection.

It is only used on the PLU connection where the application specifies in the PLU CICB that pacing requires application participation. See Pacing and Chunking for further details.
