8.2.2.2 SBAN Node Port Status Query message and response message

The SBAN node status request message is defined as SBAN-PSQ message.
The SBAN-PSQ 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 port status of the SBAN node.
Message format:

<SBAN-PSQ-Message> ::= < Message Header >
{ SDN-controller-Address }
{ SBAN-node-Address }
{ SBAN-node-ID }
{ Port-ID }

*{ Port-Type-ID }
*[ Port-Parameter-ID ]
*[ Auto-Port-ID ]
*[ Auto-Port-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) 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) Auto-Port-ID and Auto-Port-Parameter-ID are optional and have the same meaning with
item 5 and item 6, respectively. The auto here means the SBAN 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-PSQP message.

The SBAN-PSQP 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-PSQ message.

Message format:
<SBAN-PSQP-Message> ::= < Message Header >
{ SDN-controller-Address }
{ SBAN-node-Address }
{ SBAN-node-ID }

{ Port-ID }
*{ Port-Type-ID }
*[ Port-Parameter-ID ]
*{ Port-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 may be equal to Master-
Aggregate-node-Address;
