(http://integrationpatterns.com/MessageBus.html)http://integrationpatterns.com/MessageBus.html 2008 Progress Software Corporation9 SOA-23: Enterprise Integration Patterns in Sonic ESB Message Bus pattern An enterprise contains several existing systems that must be able to share data and operate in a unified manner in response to a set of common business requests. 2008 Progress Software Corporation10 SOA-23: Enterprise Integration Patterns in Sonic ESB Control Bus pattern How can we effectively administer a messaging system that is distributed across multiple platforms and a wide geographic area? (http://integrationpatterns.com/ControlBus.html)http://integrationpatterns.com/ControlBus.html 2008 Progress Software Corporation11 SOA-23: Enterprise Integration Patterns in Sonic ESB Use a Control Bus to manage an enterprise integration system. The Control Bus uses the same messaging mechanism used by the application data, but uses separate channels to transmit data that is relevant to the management of components involved in the message flow. Control Bus pattern 2008 Progress Software Corporation12 SOA-23: Enterprise Integration Patterns in Sonic ESB Guaranteed Delivery pattern How can the sender make sure that a message will be delivered, even if the messaging system fails?

The routing can be based on a number of criteria such as existence of fields, specific field values etc. (http://integrationpatterns.com/ContentBased Router.html)http://integrationpatterns.com/ContentBased Router.html 2008 Progress Software Corporation16 SOA-23: Enterprise Integration Patterns in Sonic ESB CBR pattern Incoming message routed to exactly one destination based on the content of the message 2008 Progress Software Corporation17 SOA-23: Enterprise Integration Patterns in Sonic ESB CBR pattern implementation Standard ESB Content Based Routing service xcbr rules file Routed to first rule that matches 2008 Progress Software Corporation18 SOA-23: Enterprise Integration Patterns in Sonic ESB Recipient List pattern The logic embedded in a Recipient List can be pictured as two separate parts even though the implementation is often coupled together. The first part computes a list of recipients. The second part simply traverses the list and sends a copy of the received message to each recipient. (http://integrationpatterns.com/RecipientList.html)http://integrationpatterns.com/RecipientList.html 2008 Progress Software Corporation19 SOA-23: Enterprise Integration Patterns in Sonic ESB Recipient List pattern Incoming message routed to one or more destinations based on the content of the message 2008 Progress Software Corporation20 SOA-23: Enterprise Integration Patterns in Sonic ESB Recipient List pattern implementation Standard ESB Content Based Routing service xcbr rules file Routed to all rules that match 2008 Progress Software Corporation21 SOA-23: Enterprise Integration Patterns in Sonic ESB Detour pattern The Detour uses a simple context-based router with two output channels. One output channel passes the unmodified message to the original destination. When instructed by the Control Bus, the Detour routes messages to a different channel. This channel sends the message to additional components that can inspect and/or modify the message. Ultimately, these components route the message to the same destination.

It consumes messages off the input channel and publishes the unmodified message to both output channels. To insert the Wire Tap into a channel, you need to create an additional channel and change the destination receiver to consume of the second channel. Because the analysis logic is located inside a second component, we can insert a generic Wire Tap into any channel without any danger of modifying the primary channel behavior. This improves reuse and reduces the risk of instrumenting an existing solution.

If the message content matches the criteria specified by the Message Filter, the message is routed to the output channel. If the message content does not match the criteria, the message is discarded.
