Abstract
Disclosed is a communication transport message format for carrying control information, relevant only to a transport system and end user data. The end user data is prefixed by a length field. The length field is set to a value representing the number of bytes of user data plus the size of the length field. A bit in the length field is used as a 'continuation' or more-to-come indicator. Length field values that are less than the number of bytes of the length field are used to prefix control information.
