Systems Network Architecture

networking (SNA) IBM's proprietary high level networking

protocol standard, used by IBM and IBM compatible

mainframes.

Also referred to as "Blue Glue", SNA is a bletcherous protocol

once widely favoured at commercial shops. The official IBM

definition is "that which binds blue boxes together." It may

be relevant that Blue Glue is also a 3M product commonly

used to hold down carpets in dinosaur pens.
