QUALITY OF SERVICE IN ASYNCHRONOUS MESSAGE TRANSFER

摘要

Asynchronous transfer of messages between different computing systems is accomplished using and "exactly latest" quality of service type that is implemented in a message transport infrastructure. In one aspect, in response to an action in a first computing system affecting the current state of the document, a message containing the current state of the document is posted for delivery to an outgoing message channel in a message exchange layer contained within the first system. At a time for asynchronous message transfer, and if a first quality of service type is specified for the transfer of messages containing the current state of the document, only a latest message containing the document that is posted to the outgoing message channel is forwarded for transfer to a second system.
