3 Signalling aspects

Message format:

<SBAN-NSI-Message> ::= < Message Header >
{ SDN-controller-Address }
{ SDN-application-Address }
{ SDN-application-ID }
*{ Network-service-ID }

*[ Network-service-Parameter-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) Network-service-ID uniquely specifies the network service sent by the SDN application;
5) Network-service-Parameter-ID is optional; some of the parameter status may need this ID to
specify the intended network service status.
The SBAN Network Service Initiation response message is defined as SBAN-NSIP message.

The SBAN-NSIP message, indicated by the message type in the message header field, is sent by the SDN
controller to the SDN application in response to the SBAN-NSI message.

Message format:
<SBAN-NSIP-Message> ::= < Message Header >
{ SDN-controller-Address }

{ SDN-application-Address }
{ SDN-application-ID }
*{ Network-service-ID }
*[ Network-service-Parameter-ID ]
*{ Network-service-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) Network-service-ID uniquely specifies the network service sent by the SDN application;
5) Network-service-Parameter-ID is optional, some of the status may need this ID to specify the
intended status;

6) Network-service-Status-Value is used for describing the status of the network service
specified by Network-service-ID.

9 Security considerations

The SBAN includes the forwarding function (i.e., SBAN nodes), the control function (i.e., SDN controller) of
network equipment and SDN applications, similar to the other SDN scenarios. SBAN follows the security
consideration in [ITU-T Y.3300].
