Methods and systems for enabling publish-subscribe message transmission in a distributed environment

Abstract

Messaging systems and methods for routing messages between network nodes of a distributed computing system are disclosed. The messaging system includes a plurality of network nodes. Each network node includes a shared memory comprising a shared memory region configured to store messages, a publisher, and a first bridge module. The first bridge module determines if a subscriber for a shared memory region of that network node exists on a remote network node, where the remote network node does not include the publisher. Upon determining that the subscriber exists on the remote network node, the first bridging module reads a plurality of messages from the shared memory region, and transmits the plurality of messages to a second bridge module of the remote network node. The second bridge module is configured to write the plurality of messages to a remote memory region on the remote network node.
