1 Introduction
WDS Multicast Application Protocol is a single server, multiple client protocol.
The protocol uses the WDS Multicast Transport Protocol [MS-WDSMT] for transmission of content to multiple clients. The protocol relies on services provided by the WDS Multicast Transport Protocol [MS-WDSMT] to ensure all pieces of content are delivered to all clients in a multicast session.
The protocol allows clients to join the multicast session at any point during the lifetime of the multicast session, and still be able to get all pieces of the content.
