ATD-2 TTP Traffic Management Messages 
 
Traffic Management Restriction​ messages are published as two flows: steady state and resync. 
 
Steady State messages are sent in real-time as traffic management information changes. (See ​Traffic 
Management Schema Data​ for details). 
 
Resyncs consist of ​Traffic Management Restriction​ messages being sent for current traffic management 
information. They are preceded and succeeded by ​Periodic Start​ and ​Periodic End​ messages to 
distinguish themselves from the steady state messages. The resync is intended to be used by systems 
during startup or error recovery. ​Heartbeat​ messages are sent every 4.5 minutes and contain only header 
information. 
 
A ​System Start​ message is sent out during the TTP system startup that will immediately be followed by a 
resync message. Resyncs will continue to be sent out every 15 minutes.

TTP Message Headers 
Traffic Management Restriction Messages published by TTP are JMS Text Messages, containing a 
standard JMS header augmented with TTP specific information. 
 
System start and resync start/end messages will consist of only a header. They can be distinguished by the 
SYNC and DATA_GROUP values in the header. 
 
Traffic Management Restriction messages also include a message body consisting formatted Traffic 
Management information (See ​Traffic Management Schema Data​ for details). They can be distinguished 
by the DATA_GROUP and  MESSAGE_TYPE values in the header.

Message Specific Header Properties 
  
Property Name Description 
AERODROME ID of the aerodrome the system applies to (e.g., KCLT) 
SYNC Indicates whether the message is a synchronization or flight data 
message. 
System start/sync message: sys 
Resync message: per 
Steady state message: rtm  
DATA_GROUP Identifies the TTP Service. Will always be set to 
TrafficManagementRestrictions for this service. 
MESSAGE_TYPE Used along with the SYNC header to determine the message type and 
content. 
  
Various combinations of MESSAGE_TYPE and SYNC: 
 
- SYNC= “sys”; MESSAGE_TYPE= “SystemStart” -Restart of the 
TTP service.  
 
- SYNC= “per”; MESSAGE_TYPE= “PeriodicStart” - Beginning 
of a sync event.  
- SYNC= “per”; MESSAGE_TYPE= 
“TrafficManagementRestrictions” - Contains all information 
about Traffic Management Restrictions during a sync event. 
- SYNC= “per”; MESSAGE_TYPE= “PeriodicEnd” - End of a 
sync event.  
 
- SYNC= “rtm”; MESSAGE_TYPE= 
“TrafficManagementRestrictions”  -Real time updates about 
Traffic Mgt Restrictions. 
  
- SYNC= “rtm”; MESSAGE_TYPE= “Heartbeat” - This message 
is sent periodically to convey to the consumer that their 
connection to the TTP service is still active. 
TFDM_RELEASE TFDM Release version providing this message (e.g. 12_1_B8_2P2). 
  
This property is currently not implemented for ATD-2. Value will be 
null. 
SCHEMA_VERSIO
N 
FIXM US Extension Schema Version (e.g.  4.1.1). 
TIME_STAMP Date and time of the message in Zulu time (e.g. 
"yyyy-mm-ddThh:mm:ssZ") 
UUID Universally unique identifier for the message.  This should not be used by 
the consumer and is only intended for TFDM debug purposes.

messages.
