3 Signalling aspects

3) SBAN-node-ID uniquely specifies the SBAN node;

4) Port-ID uniquely specifies the port of the SBAN node;
5) Port-Type-ID uniquely specifies the type of the port enquired by the SDN controller;
6) Port-Parameter-ID is optional, some of the status may need this ID to specify the intended
status;
7) Port-Status-Value is used for describing the status of the port specified by Port-ID.
8.2.2.3 SBAN Flow Query message and response message

The SBAN Flow Query message is defined as SBAN-FQ message.
The SBAN-FQ message, indicated by the message type in the message header field, is sent by the SDN
controller to the master aggregate node in order to get the flow information of the SBAN node.
Message format:

<SBAN-FQ-Message> ::= < Message Header >
{ SDN-controller-Address }
{ SBAN-node-Address }
{ SBAN-node-ID }
*{ Flow-ID }

*[ Flow-Parameter-ID ]
*[ Auto-Flow-ID ]
*[ Auto-Flow-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) Flow-ID uniquely specifies the flow enquired by the SDN controller;
5) Flow-Parameter-ID is optional, some of the status may need this ID to specify the intended
status;
6) Auto-Flow-ID and Auto-Flow-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 Flow Query response message is defined as SBAN-FQP message.
The SBAN-FQP 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-FQ message.
Message format:

<SBAN-FQP-Message> ::= < Message Header >
{ SDN-controller-Address }
{ SBAN-node-Address }
{ SBAN-node-ID }
*{ Flow-ID }

*[ Flow-Parameter-ID ]
*{ Flow-Status-Value }
