4Secure Message Queue Transport
4MQT is a lightweight application to facilitate the transfer of AMQP and MQTT messages across a segregated one-way link. 4MQT supports all conformant AMQP and MQTT implementations and works as a ‘greedy consumer’.
4MQT can be utilised to enable high availability and scalable data transfer. 4MQT typically runs onboard the OPDS platform but can also run on some linux flanking systems. In addition to transfer capability, 4MQT producers also have the ability to perform XML and JSON schema checks on messages before they are published to the broker.
Digital electronics or digital (electronic) circuits are electronics that operate on digital signals. In contrast, analog circuits manipulate analog signals whose performance is more subject to manufacturing tolerance, signal attenuation and noise.
