Abstract: A data processing system and method of data processing are provided. The system comprises first and second data processing agents and data storage shared coherently between the both data processing agents to store a message data structure to provide a message channel between them. A further data storage is accessible to both data processing agents to store message channel metadata, which provides message status information for the message channel. The message channel metadata is one of a plurality of message channel metadata types defined for a corresponding plurality of message channel types between the first and second data processing agents, and at least one of the first and second data processing agents is responsive to an initialization trigger to establish the message channel with a selected message channel type.
