The multicast session has designated a client as the Master Client and is sending data provided by the WDS Multicast Application Protocol.

SessionState MUST be set to PreStartState on initialization.

Multicast Address: A multicast IP address and UDP port assigned to the multicast session by the server. The WDS Multicast Session Initiation Protocol, as specified in [MS-WDSMSI], provides the multicast address for use by multicast session.

Unicast Address: An IP address of the network interface card and a UDP port being used by the multicast session to communicate to clients. The WDS Multicast Session Initiation Protocol, as specified in [MS-WDSMSI], provides the unicast address for use by the multicast session.

SessionId: An ID assigned to the multicast session by the server; MUST be unique across all multicast sessions on the server. The WDS Multicast Session Initiation Protocol, as specified in [MS-WDSMSI], provides the session ID for use by the multicast session.

NextClientId: A 32-bit numeric value that specifies the ID to assign to the next client that joins the multicast session; MUST be set to a random 32-bit value on initialization.

Server Security Mode: Specifies the security mode for packets sent by the server. The WDS Multicast Session Initiation Protocol, as specified in [MS-WDSMSI], provides the server security mode.

Client Security Mode: Specifies the security mode for packets sent by the client. The WDS Multicast Session Initiation Protocol, as specified in [MS-WDSMSI], provides the client security mode.
