3 Signalling aspects

Message format:

<SBAN-SQ-Message> ::= < Message Header >
{ SDN-controller-Address }
{ SBAN-node-Address }
{ SBAN-node-ID }
*{ Node-Type-ID }

*[ Node-Parameter-ID ]
*[ Auto-Node-ID ]
*[ Auto-Node-Parameter-ID ]

Meanings and explanations:
1) SDN-controller-Address uniquely specifies the SDN controller;
2) SBAN-node-Address uniquely specifies the SBAN node address, which may be equal to Master-
Aggregate-node-Address;
3) SBAN-node-ID uniquely specifies the SBAN node;
4) Node-Type-ID uniquely specifies the type of status enquired by the SDN controller;
5) Node-Parameter-ID is optional, some of the status may need this ID to specify the intended
status. One possible example would be the port number (or ID) of the designated port;
6) Auto-Node-ID and Auto-Node-Parameter-ID are optional and have the same meaning with
item 4 and item 5, respectively. The auto here means the aggregate node will automatically report
the specified status to the SDN controller in case of changes.

The SBAN node status response message is defined as SBAN-SQP message.
The SBAN-SQP message, indicated by the message type in the message header field, is sent by the master
aggregate node to the SDN controller in response to the SBAN-SQ message.
Message format:
<SBAN-SQP-Message> ::= < Message Header >

{ SDN-controller-Address }
{ SBAN-node-Address }
{ SBAN-node-ID }
*{ Node-Type-ID }
*[ Node-Parameter-ID ]

*{ Node-Status-Value }
Meanings and explanations:
1) SDN-controller-Address uniquely specifies the SDN controller;
2) SBAN-node-Address uniquely specifies the SBAN node address, which is equal to
Master-Aggregate-node-Address;
3) SBAN-node-ID uniquely specifies the SBAN node;

4) Node-Type-ID uniquely specifies the type of status enquired by the SDN controller;
5) Node-Parameter-ID is optional, some of the status may need this ID to specify the intended
status. One possible example would be the port number (or ID) of the designated port;

6) Node-Status-Value is used for describing the status of the SBAN node specified by
Node-Type-ID.
