Abstract
In a publish/subscribe data processing broker network having a plurality of broker data processing apparatuses each of which has an input for receiving published messages directly from a publisher application and/or receiving subscription data from a subscriber application, a first broker apparatus has: a software unit for receiving via said input subscription data from a subscriber application; a software unit for providing an acknowledgement to said subscriber application to acknowledge that the subscription data has been received; a software unit for propagating said subscription data to a group of other broker apparatuses; a software unit for determining whether said means for propagating has propagated said subscription data to the group of other broker apparatuses; and a software unit for receiving via said input an indication from said subscriber application that said acknowledgement should not be sent to the subscriber application until the means for determining has determined that said means for propagating has propagated said subscription data to the group of other broker apparatuses.
