3 Signalling aspects

The SBAN-RE message, indicated by the message type in the message header field, is sent by the master
aggregate node to be registered in the SDN controller.

Message format:
< SBAN-RE-Message > ::= < Message header >
{ SDN-controller-Address }
{ Master-Aggregate-node-Address }
*{ Slave-Aggregate-node-Address }
*{ SBAN-node-Attribute }

Meanings and explanations:
1) SDN-controller-Address uniquely specifies the SDN controller;

2) Master-Aggregate-node-Address uniquely specifies the master aggregate node;
3) Slave-Aggregate-node-Address uniquely specifies the slave aggregate node. There may be
multiple slave aggregate nodes;

4) SBAN-node-Attribute is used for the aggregate node attributes. There may be multiple node
attribute items.

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

{ SDN-controller-Address }
{ Master-Aggregate-node-Address }
{ SBAN-node-ID }
{ Result }

Meanings and explanations:
1) SDN-controller-Address uniquely specifies the SDN controller;

2) Master-Aggregate-node-Address uniquely specifies the master aggregate node, which may be
renamed as SBAN-node-Address when the master aggregate node represents SBAN node;

3) SBAN-node-ID uniquely specifies the SBAN node, which is assigned by the SDN controller and is
globally validated. After the SBAN node has registered successfully, this ID is used in subsequent messages,
including the messages from the SDN controller to the SBAN node and from the SBAN node to the SDN
controller;
4) Result shows the handling results of registering the SBAN node in the SDN controller.

8.2.1.2 SBAN Node Port Register message and response message
The port information of the SBAN Node Port Register message is defined as SBAN-PR message.

The SBAN-PR message, indicated by the message type in the message header field, is sent by the master
aggregate node to be registered in the SDN controller.
