Transport
Peer-to-Peer
Topology
The API implementations see more detail,
under the covers of AMQP.
In addition to MOM messaging, they
have to deal with the details of maintaining
and securing a network connection
between the client and the broker.
This is how the lower level transport
stack looks to a systems engineer.

Broker-to-Broker
Global
Forwarding
Global addressing will relay messages
from local queues on a client-local
broker to queues resident on the
destination organisations broker.
This is very similar to SMTP.
Also, as
with SMTP relaying is strongly
discouraged as it may compromiser.

End-to-End
MOM Topology
(WORK+)
This is the message transmission path
as the sending and receiving applications
perceive it.
It is important to note that the Message
transmission path is a game of
two halves; the deposit in a queue
half, and the collect from the queue
half.
This decoupling of sender and recipient
is the prime purpose of message
oriented middleware.

Diagram
This diagram shows the perceived
entities which the client an discover in
a compliant broker, and the relationships
between them.
A compliant broker may be implemented
differently, but MUST exhibit
these same perceivable entities.

Queues
Delivery into queues is the first half of
the end-to-end MOM delivery process.

Queues
I'm using the name “Stable Queues”
(a la Stable Storage) to encompass
the idea of a safety-deposit-box style
drop-point.
Collecting Messages from Queues in a
configurable way is the second half of
the MOM end-to-end process.

Message
Consumer /

Here, the JMS Selector concept is
modelled using AMQP Selector + Consumer
to pick Messages from the
Queue.

AMQP
PubSub can be
implemented
in 2 ways
1. MessageConsumer
2. TopicSubscriber
Here, the JMS Selector concept is
modelled using a Queue to represent
the Topic and AMQP Bindings to route
Messages from the Topic using Topic
Bindings to copy the Messages into
Private Queues, one Private Queue for
each subscriber to the Topic.

Global Addressing
Internet
Subscription
The aim of Global Subscription Relay
is to enable de-queuing of information
from a well known Address Queue
within another organisation, whilst
adhering to good Internet Security
practices.
The direction of connection initiation
should always be from higher trust
zones to lower trust zones.
Because of the active nature of this
activity, concerns to robustness and
prevention of resource abuse are
paramount...
