ETP Message Approach

For StandardETP v1.1

ETP has been designed to support multiple patterns, or styles of message transfer, especially with respect to message size, frequency, and complexity. Separate subprotocols of ETP are generally related to specific kinds of messages. This practice is somewhat in contrast with previous Energistics data service specifications, where each SIG had service contracts that were unique to the domain objects of that SIG. With ETP, the goal is to use a single set of protocols across multiple domain areas, with the differences in protocol focused more on the communication requirements. The initial release of ETP focused on high-speed streaming of channel data as described below.
