	15	+The asynchronous routing has three relevant parts:

	17	+* All asynchronous onramps send their data to the routing
	18	+* Based on a decision made within the routing the message is routed to one or more offramp queues
	19	+* Each offramp queue will receive data based on the decision unless you add another filter before the messages are sent to the offramp queue

57		-As the asynchronous routing plays a role in routing messages between all asynchronous flows in the messaging solution you can imagine that making changes does not need to happen lightly. The other aspect is that when multiple projects are being built at the same time the asynchronous routing will house a multitude of changes that need to go to Acceptance or Production at the same time.

59		-One control mechanism we consider a best practice to guard yourself against those risks is to add a filter before data is placed on the offramp queue.
60		-By doing this consistently you can control when a specific offramp can receive data on any environment. In other words, when a certain system is not ready yet to receive data on Acceptance or Production but is ready on Test you can control this behavior with this solution.
