3.1.4 Higher-Layer Triggered Events

The multicast session is initialized when a client requests content using the WDS Multicast Session Initiation Protocol for delivery, as specified in [MS-WDSMA].

An administrator action can cause a kick trigger to be sent, causing the multicast session to remove a client from the multicast session. The kick trigger MUST be processed as specified in section 3.1.5.6.

An administrator action can cause a demote trigger to be sent, causing the multicast session to demote a client to a lower speed multicast session. Demote triggers are processed as specified in section 3.1.5.10.

The WDS Multicast Application Protocol, as specified in [MS-WDSMA], can cause a POLL trigger to ask the WDS Multicast Transport Protocol to send a payload to all clients using a POLL packet. The POLL trigger is processed as specified in section 3.1.5.4.

The WDS Multicast Application Protocol, as specified in [MS-WDSMA], can cause a data trigger in order to provide a data payload to be sent using this same protocol. The data trigger is processed as specified in section 3.1.5.9.4.
