One thing that confused me through this model, is that how each processor keeps its directory's consistant with each other cores. However this is not the case as each processor's directory is responsible for a subset of the address space.

A factor that can increase latency with this protocol (as it does with snooping-based coherence protocols) is the wait for the acknowledgement signal from the other processor's cache.
