Signalling aspects 3

8.3.2 Signalling requirements for querying status

8.3.2.1 SDN application Status Query message and response message
The SDN application Status Query message is defined as APP-ASQ message.

The APP-ASQ message, indicated by the message type in the message header field, is sent by the SDN
controller to the SDN application in order to get the status of the SDN application.
Message format:
<APP-ASQ-Message> ::= < Message Header >

{ SDN-controller-Address }
{ SDN-application-Address }
{ SDN-application-ID }
*{ SDN-application-Attribute-ID }

Meanings and explanations:
1) SDN-controller-Address uniquely specifies the SDN controller;
2) SDN-application-Address uniquely assigned to the SDN application;
3) SDN-application-ID uniquely specifies the SDN application;
4) SDN-application-Attribute-ID is used for the SDN application attributes. There may be
multiple SDN application attribute items.

The SDN application Status Query response message is defined as APP-ASQP message.
The APP-ASQP message, indicated by the message type in the message header field, is sent by the SDN
application to the SDN controller in response to the APP-ASQ message.
Message format:
<APP-ASQP-Message> ::= < Message Header >
{ SDN-controller-Address }

{ SDN-application-Address }
{ SDN-application-ID }
*{ SDN-application-Attribute-ID }
*{ SDN-application-Status-Value }

Meanings and explanations:
1) SDN-controller-Address uniquely specifies the SDN controller;
2) SDN-application-Address uniquely assigned to the SDN application;
3) SDN-application-ID uniquely specifies the SDN application;
4) SDN-application-Attribute-ID is used for the SDN application attributes. There may be
multiple SDN application attribute items;
5) SDN-application-Status-Value is used for describing the status of the SDN application
specified by SDN-application-Attribute-ID.

8.3.2.2 SBAN Network Query message and response message
The SBAN network status request message is defined as SBAN-NQ message.

The SBAN-NQ message, indicated by the message type in the message header field, is sent by the SDN
application to the SDN controller in order to get the network status of the SBAN.
