Directory Coherence Protocols
In this chapter, we present directory coherence protocols. Directory protocols were originally developed to address the lack of scalability of snooping protocols. Traditional snooping systems broadcast all requests on a totally ordered interconnection network and all requests are snooped by all coherence controllers. By contrast, directory protocols use a level of indirection to avoid both the ordered broadcast network and having each cache controller process every request.
