This read-create value, in cells per second, configures the Sustainable Cell Rate (SCR) for traffic in the remote-to-local direction of this connection. An admin sets this to define the average long-term rate the connection is expected to sustain from the remote endpoint, distinct from the burst-oriented peak cell rate. For example, for a VBR connection expecting bursty but bandwidth-averaged inbound traffic, the admin would configure this sustainable rate below the remote PCR to describe the connection's realistic average throughput.
