AMQP is a standard wire-level protocol and semantic framework for high performance enterprise messaging.
From the AMQP website:
AMQP is an Open Standard for Messaging Middleware.
By complying to the AMQP standard, middleware products written for different platforms and in different languages can send messages to one another. AMQP addresses the problem of transporting value-bearing messages across and between organisations in a timely manner.
AMQP enables complete interoperability for messaging middleware; both the networking protocol and the semantics of broker services are defined in AMQP.
For more information on what AMQP is, please see the AMQP Working Group's overview page.
