Mechanism for connecting disparate publication and subscribe domains via the internet

摘要

The invention uses two channel adapters to couple to publication and subscription (PUB/SUB) systems together via the Internet. Each channel adapter is based on the existing PUB/SUB engine of that domain, as well as the protocol used in the network channel between the adapters. For transport across the network, the inventive adapters convert the event information into a format acceptable by the network. The delivered information is then reconverted back into the event format for use in the other domain. To guarantee delivery across the network, the inventive adapters use plurality of states and status messages to indicate the status of delivery, receipt, and publication of the events. The communication between the adapters is bidirectional such that one pair of adapters manages all event traffic between two publish/subscribe domains. The adapters store the events in repositories, and maintain separate queues for inbound and outbound events.
