1 Introduction

The WDS Multicast Transport Protocol is a multiple clients/single server protocol.

The protocol, in conjunction with the WDS Multicast Application Protocol, as specified in [MS-WDSMA] allows transmission of content to multiple clients using multicast UDP. The protocol provides a best effort mechanism for delivery of data to all clients.

The protocol provides mechanisms to allow clients to join a multicast session at any point during the lifetime of a multicast session and still be able to download content completely.

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
