It acts as a guideline to the user to input the necessarily required detail, which could be in the form of short notes and write-ups. Both types of routing slips achieve a similar function: one relating to computerized interoffice communications and the other to traditional interoffice communications.

Sometimes, though, we need to route a message not just to a single component, but through a whole series of components. Let's assume, for example, that we use a Pipes and Filters architecture to process incoming messages that have to undergo a sequence of processing steps and business rule validations.

Since the nature of the validations varies widely and may depend on external systems e. Each filter inspects the incoming message, and applies the business rule s to the message. If the message does not fulfill the conditions specified by the rules it is routed to an exception channel. The channels between the filters determine the sequence of validations that the message needs to undergo. Now let's assume, though, that the set of validations to perform against each message depends on the message type for example, purchase order request do not need credit card validation or customers who send orders over a VPN may not require decryption and authentication.

To accommodate this requirement we need to find a configuration that can route the message through a different sequence of filters depending on the type of the message. 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?

Attach a Routing Slip to each message, specifying the sequence of processing steps. Wrap each component with a special message router that reads the Routing Slip and routes the message to the next component in the list. We insert a special component into the beginning of the process that computes the list of required steps for each message.

It then attaches the list as a Routing Slip to the message and starts the process by routing the message to the first processing step. After successful processing, each processing step looks at the Routing Slip and passes the message to the next processing step specified in the routing table.

In this blog post, I'll explain in depth the routing slip pattern and how you can leverage it within enterprise integration scenarios.

As always I'll have a look at the benefits, but also the pitfalls will get some well-deserved attention. A routing slip is a configuration that specifies a sequence of processing steps services. This routing slip must be attached to the message to be processed. Each service processing step is designed to receive the message, perform its functionality based on the configuration and invoke the next service. In that way, a message gets processed sequentially by multiple services, without the need of a coordinating component.

The schema below is taken from Enterprise Integration Patterns. An example of a simple routing slip can be found below. The header contains the name of the routing slip and a counter that carries the current step number. Each service is represented by a routing step. A step has its own name to identify the service to be invoked and has a specific key-value configuration pairs.

Remark that this is just one way to represent a routing slip. Feel free to add your personal flavor…. When defining a service, you need to design it to be generic. The executed logic within the service must be based on the configuration, if any is required. Think on the desired way to invoke services. If required, a combination of sync and async can be supported.

Integrations are composed of reusable and configurable building blocks. The routing slip pattern forces you to analyze, develop and operate in a streamlined manner. Reuse is heavily encouraged on different levels: the way analysis is performed, how patterns are implemented, the way releases are rolled out and how operational tasks are performed.

One unified way of working, built on reusability. Your integration is completely driven by the assigned routing slip. There are no hard-coded links between components. This allows you to change its behavior without the need of a re-deployment.

This configuration also serves as a great source of documentation, as it explains exactly what message exchanges are running on your middleware and what they exactly do. Once you have set up a solid routing slip framework, you can increase your release cadence. By leveraging your catalogue of reusable services, you heavily benefit from previous development efforts.

Just update the routing slip configuration and it has an immediate effect on your production workload. A routing slip is agnostic to the underlying technology stack. The way the routing slip is interpreted, is of course specific to the technology used.

This introduces ways to have a unified integration solution, even if it is composed of several different technologies. It enables also cross technology message exchanges.

As an example, you can have an order that is received via an AS2 Logic App, being transformed and sent to an on premise BizTalk Server that inserts it into the mainframe, all governed by a single routing slip config. If a message encounters an issue, operations personnel can immediately consult the routing slip to see where the message comes from, what steps are already executed and where it is heading to.

This visibility can be improved, by updating the routing slip with some extra historical information, such as the service start and end time. Why even not including an URL in the routing slip that points to a wiki page or knowledge base about that interface type? Not every integration project is well-suited to use the routing slip pattern.

When a high level of reusability is detected, the routing slip pattern might be a good fit. A common pitfall is adding too much complexity into the routing slip. Try to stick as much as possible to a sequential series of steps services that are executed. Some conditional decision logic inside a routing slip might be acceptable, but define clear boundaries for such logic.

Do not start writing you own workflow engine, with its own workflow language. Keep the routing slip logic clean and simple, to stick to the purpose of a routing slip. In case of maintenance of the surrounding systems, you often need to stop a message flow. One option is to stop a message exchange at its source, e. You can stop the generic service that sends a message to SAP, but then you also stop sending other message types… Think about this upfront!

A very common pain-point of a high level of reuse, is the impact of upgrading a generic service that is used all over the place. There are different ways to reduce the risks of such upgrades, of which automated system testing is an important one.

Within the routing slip, you can specify explicitly the version of a service you want to invoke. In that way, you can upgrade services gradually to the latest version, without the risk of a big bang deploy. Define a clear upgrade policy, to avoid that too many different versions of a service are running side-by-side.

A message exchange is spread across multiple loosely coupled service instances, which could impose a monitoring challenge. Many technologies offer great monitoring insights for a single service instance, but lack an overall view across multiple service instances. Introducing a correlation ID into your routing slip, can highly improve the monitoring experience.

This ID can be generated the moment you initialize a routing slip. Routing slips are a very powerful mechanism to deliver unified and robust integrations in a fast way.

Feel free to add your personal flavor… Assign Routing Slip There are multiple ways to assign a routing slip to a message. A service must consist of three steps: Receive the message Process the message, based on the routing slip configuration Invoke the next service, based on the routing slip configuration There are multiple ways to invoke services: Synchronous : the next service is invoked without any persistence in between e.

Asynchronous : the next service is invoked with persistence in between e. Configuration based Your integration is completely driven by the assigned routing slip. Faster release cycles Once you have set up a solid routing slip framework, you can increase your release cadence.

Technology independent A routing slip is agnostic to the underlying technology stack. Pitfalls Not enough reusability Not every integration project is well-suited to use the routing slip pattern.

Too complex logic A common pitfall is adding too much complexity into the routing slip. Limited control In case of maintenance of the surrounding systems, you often need to stop a message flow. Hard deployments A very common pain-point of a high level of reuse, is the impact of upgrading a generic service that is used all over the place.
