Summary: We present a novel approach to compare process calculi and their synchronisation mechanisms by using synchronisation patterns and explicitly considering the degree of distributability. For this, we propose a new quality criterion that (1) measures the preservation of distributability and (2) allows us to derive two synchronisation patterns that separate several variants of pi-like calculi. Precisely, we prove that there is no good and distributability-preserving encoding from the synchronous pi-calculus with mixed choice into its fragment with only separate choice, and neither from the asynchronous pi-calculus (without choice) into the join-calculus.
