22.214.171.124 Identifying ETP Protocols
|For Standard||ETP v1.1|
Each of the ETP protocols is assigned a numeric identifier as part of this specification, and all messages are identified with this number in the message header. The Core protocol is Protocol 0, and the initial channel data protocol is Protocol 1. This pattern of assigning numeric identifiers to key enumerations in the protocol is used regularly, to allow for the smallest, most efficient binary transfers.
