How Oracle SOA Suite and OSB Communicates?

There are four types of communication by which Oracle SOA Suite and Oracle Service Bus
communicates.

1. OSB invoking SOA/SCA Synchronously: The direct Binding component of SOA/SCA is invoked by the OSB business service,through SOA Direct Transport.                                             
2. OSB invoking SOA/SCA Asynchronously: The direct Binding component of SOA/SCA is invoked by the OSB business service,through SOA Direct Transport and the call-back message from the BPEL service will be handled by an OSB proxy service through the Service Bus Transport.                                                                                                                                          
3. SCA/SOA invoking OSB Synchronously: The OSB consists of a proxy service, accepting the call from a SOA suite mediator component through Service Bus Transport.                                   
4. SCA/SOA invoking OSB Asynchronously: The OSB consists of a proxy service, accepting the call from a SOA suite mediator component through Service Bus Transport and call-back messages are implemented in asynchronous manner.
