What is GSP in this context? Searching Python GSP brings up Generalized Sequence Pattern (GSP) algorithm [1] and Graph Signal Processing [2], neither of which seem to be a protocol. I also found "Generic Signaling Protocol" and "Global Sequence Protocol" which also don't seem relevant. Forgive me if GSP is some well know thing which I am just not familiar with.
