h2. Definition of our integration process

Today you will bufferize messages, to process them all in one by _MathOperations_.


You will use Enterprise Integration Patterns (EIP, see below for explanations) to create this process :
* Several messages are sent to an *EIPAggregator* pattern, which bufferize all incoming messages.
* Trigger message is sent to *EipAggregator.*
* *EipAggregator* sends an aggregated message to *EipSPlitter*.
* *EipSplitter* splits the aggregated message back into multiple messages.
* *EipSPlitter* sends the multiple messages to the operation *AddIntegers* on the service *MathOperations.*
* *MathOperations.AddIntegers* processes the messages and send you the responses.
