Universal Messaging is fast, reliable, scalable, and flexible Java message-oriented middleware (MOM) that provides messaging functionality such as clustering, scheduling, and interface plug-ins, with standard support for the messaging paradigms of publish/subscribe, message queues, and P2P, as well as support for JMS. Universal Messaging also supports a significant part of the AMQP 1.0 standard wire protocol for messaging, specifically the parts that are exposed through the JMS API.

Universal Messaging serves as the intermediary that routes data from publishers to subscribers. It can function as the messaging backbone for resources across your enterprise and can support an event-driven architecture, in which subscribers receive documents and then perform predefined actions. Integration Server can encode/decode those documents as protocol buffers.
