# OASIS AMQP 1.0

Protocols · `AMQP 1.0` · verification: source checked

AMQP 1.0 is an OASIS standard open internet protocol for business messaging. It defines a binary wire-level protocol and a layered specification covering a peer-to-peer transport over TCP, a type system and encoding, a message format, transactions, and security layers. It is symmetric, with no wire-level distinction between clients and brokers.

## Specification

| Property | Value |
|---|---|
| Transports | tcp |
| Architecture | client server |
| Encoding | binary |
| Standard body | OASIS |
| Standard ref | AMQP 1.0 |

## Study notes

- Published as an OASIS Standard on 29 October 2012.
- The specification is organized as Parts 0-5: Overview, Types, Transport, Messaging, Transactions, and Security, plus an XML DTD.
- The protocol is symmetric: it defines no wire-level distinction between clients and brokers.
- Part 1 defines the AMQP type system and type encodings that every conformant implementation must implement.
- Part 2 defines a peer-to-peer transport protocol that operates over TCP; conformant implementations over TCP must implement Part 2.
- Part 3 defines the messaging layer and message format; implementations that process messages must implement it.
- Part 4 defines transactional messaging with two roles: transactional resource and transaction controller.
- Part 5 defines security layers for authenticated and/or encrypted transport.
- Conformant implementations must perform protocol negotiation and parse, process, and produce frames according to Parts 1 through 5.
- Conformant implementations must not require extensions outside the specification to interoperate with other conformant implementations.
- TCP server role implementations are strongly recommended to support SASL PLAIN and SCRAM-SHA1 mechanisms.
- TCP client role implementations should be configurable to connect to TCP server implementations following the security recommendations.
