Signalling aspects 3

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 flow may need this ID to specify the intended status;
6) Flow-Status-Value is used for describing the status of the flow specified by Flow-ID.
8.2.3 Signalling requirements for service creation

8.2.3.1 SBAN Flow Initiation message and response message

The SBAN Flow Initiation message is defined as SBAN-FI message.
The SBAN-FI message, indicated by the message type in the message header field, is sent by the SDN
controller to the aggregate node in order to initiate the flow in the SBAN node.
Message format:

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

*[ 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) Port-ID uniquely specifies the port of the SBAN node;
5) Flow-ID uniquely specifies the flow sent by the SDN controller;
6) Flow-Parameter-ID is optional; some of the parameter status may need this ID to specify the
intended flow status.
The SBAN Flow Initiation response message is defined as SBAN-FIP message.

The SBAN-FIP 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-FI message.

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

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