Description

[0002] A gateway, also known as a network connector or protocol converter, implements network interconnection above the network layer. It is a complex network interconnection device used only to connect two networks with different high-level protocols. Gateways can be used to interconnect both wide area networks (WANs) and local area networks (LANs). Industrial Internet gateways require a network cable to operate.
