Bus snooping

Bus snooping or bus sniffing is a scheme that a coherency controller (snooper) in a cache monitors or snoops the bus transactions in order to maintain a cache coherency in distributed shared memory systems. A cache that has a coherency controller (snooper) inside is called as Snoopy cache. The scheme was introduced by Ravishankar and Goodman in 1983.
