4Secure Message Queue Transport (4MQT™)
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.
