This plugin works by splitting a payment that has to be relayed, into separate payments. One of the payments will follow the original route to the next node, keeping the original onion. The other payments will be routed via an alternative route to that next node. The next node will collect all payments and continue the payment as usual.

When the payment is successful, the Payer will receive a message that the payment succeeded in one part. The Payer will not have any knowledge about the route having been split downstream. In this sense, PSS is different from multi-path payments (MPP). MPP is initiated by the Payer, whereas PSS happens downstream from the Payer without the Payer’s involvement.
