Is SCPS protocol supported on a Citrix SD-WAN WANOP appliance?

Yes. The Citrix SD-WAN WANOP appliance supports SCPS protocol and accelerate data transferred using this protocol.

Can I use an SCPS-enabled appliance with a non-SCPS-enabled appliance?

Yes. If you must mix SCPS-enabled appliances with non-SCPS-enabled appliances, deploy them in such a way that mismatches do not occur. You can either use IP-based service class rules or arrange the deployment so that each path has matching appliances.

What happens if I use an SCPS-enabled appliance at one end non-SCPS-enabled appliance on the other end of the link?

If the appliance on one end of the connection has SCPS enabled and one does not, retransmission performance suffers. This condition also causes an “SCPS Mode Mismatch” alert.

What is the difference between the behavior of a SCPS-enabled appliance and default appliance?

The main difference between a SCPS-enabled and the default appliance behavior is that SCPS-style “selective negative acknowledgements” (SNACKs) are used instead of standard selective acknowledgements (SACKs).
