Protocol Features
AMQP
Advanced Message Queuing Protocol (AMQP) is an Open Messaging Middleware standard upon which Qpid's wire protocol is based. The standard is maintained by the AMQP Working Group. Currently the following versions of the protocol exist:
- 0-8, released June 2006. This is the first working version of AMQP.
- 0-9, released December 2006. This version improves reliability aspects of the protocol.
- 0-10, released (no idea when).
- 1-0, not yet released, is slated to be the first final release of AMQP. Version 1-0 is currently in final draft (PR2).
