Tempus Edge Messaging

Standard message formatting should be used by all edge applications. The purpose of standard message formatting is:

• reduce message parsing cost
• promote reusability between edge applications
• maintain flexibility for future edge application requirements
• improve the ease of application debugging

Message Anatomy

A Tempus Edge message is a single byte array that lives in the contentdata field of an IoFog message.

In general, Tempus Edge messages consist of 3 parts:

protocol:first byte of the array defining the Tempus Edge message protocol to use. type:optional second byte of the array defining the Tempus Edge message type for the given protocol. payload:optional remaining byte array containing a serialized protobuf message of the type defined by type.
