Content Based Router

How do we handle a situation where the implementation of a single logical function (e.g., inventory check) is spread across multiple physical systems?

Message Filter

How can a component avoid receiving uninteresting messages?

Dynamic Router

How can you avoid the dependency of the router on all possible destinations while maintaining its efficiency?

Recipient List

How do we route a message to a list of (static or dynamically) specified recipients?


How can we process a message if it contains multiple elements, each of which may have to be processed in a different way?


How do we combine the results of individual, but related messages so that they can be processed as a whole?


How can we get a stream of related but out-of-sequence messages back into the correct order?

Composed Message Processor

How can you maintain the overall message flow when processing a message consisting of multiple elements, each of which may require different processing?


How do you maintain the overall message flow when a message needs to be sent to multiple recipients, each of which may send a reply?

Routing Slip

How do we route a message consecutively through a series of processing steps when the sequence of steps is not known at design-time and may vary for each message?


How can I throttle messages to ensure that a specific endpoint does not get overloaded, or we don't exceed an agreed SLA with some external service?


How can I sample one message out of many in a given period to avoid downstream route does not get overloaded?


How can I delay the sending of a message?

Load Balancer

How can I balance load across a number of endpoints?


How can I route a message to a number of endpoints at the same time?


How can I repeat processing a message in a loop?
