2 -In this microlearning, we will explain the basics of asynchronous routing that plays a vital role in the distribution of messages within the five-layer model of messaging.
2 +In this microlearning, we will dive into the essentials of asynchronous routing and its importance in managing message distribution within the five-layer messaging model. We will cover the key concepts, including how to route messages efficiently and manage output control.

65 65  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.
66 66  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.
