	The '''System Communication Architecture''' (given as '''Systems Communication Architecture''' in some documents) is [[Digital Equipment Corporation\|DEC]]'s [[data network]]ing [[architecture]] for [[VAXcluster]] systems; it defines the major constituent [[protocol]]s, what functions each one performs, and how they interact. It allows the basic data-communication mechanism of a VAXcluster, the [[Computer Interconnect]], to be shared between the numerous functions needed to operate the VAXcluster.
