A '''packet switch''' is a switching node in a data transmission network using [[packet]]s (as opposed to [[circuit switching]]).

The first packet switches were [[minicomputer]]s provided with [[serial line]] interfaces (since [[synchronous]] serial lines the only data transmission technology available for the first packet data networks), such as the [[Interface Message Processor]s of the [[ARPANET]].

The early generations of [[router]]s, used in the first decades of the [[Internet]], were similar, but could use interfaces to the various [[local area network]] technologies (e.g. [[Ethernet]]).

More recently, very high speed packet switches use custom [[hardware]].
