1.3 Overview

A typical interaction between client and server involves the following:

1. The client has already obtained the following information.

   • Name or IP address of server.

   • Name of multicast namespace.

   • Name of the content in multicast namespace.

2. The client uses the Multicast Session Initiation Protocol to request content in the multicast namespace be set up for delivery using multicast transmission.

3. On receiving the request, the server sets up the multicast session for the specified content in the multicast namespace and sends the details of the multicast session to the client.
