You’re obviously thinking of a token-bucket based shaper here. CAKE uses a deficit-mode shaper which deliberately works a different way - it’s more accurate on short timescales, and this actually makes a positive difference in several important cases.
The good news is that there probably is a way to explicitly and efficiently share bandwidth in any desired ratio across different CAKE instances, assuming a shared-memory location can be established. I don’t presently have the mental bandwidth to actually try doing that, though.
