Whereas synchronous drawbridges are based on component technologies, asynchronous drawbridges are based on message queues.
The message queues that are used for asynchronous drawbridges are both persistent and transactional.
The insertion of an infogram is transactionally coordinated with work being done by the donor fortress by DTC, the distributed transaction coordinator.
The receipt of an infogram is also transactionally coordinated by DTC, this time with work being done by the recipient fortress.
Sending of the infogram is fairly well coupled with receipt of the infogram.
Homogeneous asynchronous drawbridges are based on a configuration in which a component veneer is placed over ...
