<b>IE and the AE deployed in the different machine?</b>

Thats not necessary.Generally both the engine lies in the same system...but to increase the perfomance some decentralized AE's are also used in diffren system..

IE is in ABAP stack where as AE is in JAVA stack....they communicate internelly using Jco connector...

Hi Joy

The Integration Server is the SAP Exchange Infrastructure runtime component for receiving messages and controlling how these messages are forwarded. During configuration of the XI system landscape, an SAP Web AS client is assigned the role of Integration Server. The following two engines work together in this client to control the message flow:

· The Integration Engine is responsible for central Integration Server services, for example, routing and mapping.

· The Business Process Engine is responsible for executing and persisting integration processes.

Furthermore, the majority of the adapters run on the central Adapter Engine, which is installed on the J2EE Engine of the SAP Web AS, and which can take over inbound and outbound processing on the Integration Server from the Integration Engine. In this way, the central services of the Adapter Engine (for example, persistence), can be used by all adapters.

Thanks !!

If i remember correct it is HTTP

IE and AE are generally installed on the same SAP instance, but then for perfomance/connectivity reasons you can also have multiple AE installed on different machines and connected to the same IE.
