Abstract
An event exchange mechanism for software systems is disclosed that utilizes a receiver-driven, publisher-subscriber model to overcome various problems in the prior art. The event exchange has a flexible addressing scheme so that a sending module need not be aware of all of its receiving modules. Yet, the event exchange still provides the ability to multicast messages to interested receivers. The system is also uniform since both data and control information can be exchanged using the same mechanism. Mechanisms for flow control are also provided so that a receiver can exert backpressure on a sender; this is especially useful for the transfer of multimedia data.
