# Multi-Protocol Gateway
This section introduces multi-protocol gateways, including ZMQ gateway, SOME/IP Gateway, and DDS Gateway.
The ZeroMQ (also known as ØMQ, 0MQ, or zmq) gateway allows the bridging of ZMQ applications with MQTT systems.
The SOME/IP gateway is responsible for transforming MQTT messages into SOME/IP messages and vice versa. SOME/IP is a middleware solution for automotive Ethernet-based E/E (electrics/electronics) systems.
DDS (opens new window) is a standard for high-performance, scalable, real-time, platform-independent, and predictable publish-subscribe messaging. The Object Management Group (OMG) manages the standard. Cyclone DDS (opens new window) is a popular implementation of the DDS standard.
