Chapter 2 Inside Mac OS X Server 47
IP Failover
You can configure IP failover to help maximize server availability.
IP failover is a way to set up a standby server that will take over if the primary server
fails. The standby server takes over the IP address of the failed server, which takes the IP
address back when it is online again. IP failover is useful for DNS servers, web servers
hosting websites, media broadcast servers, and other servers that require minimal data
replication.
Media Streaming and Broadcasting
QuickTime Streaming Server (QTSS) lets you stream multimedia in real time using the
industry-standard RTSP/RTP protocols. QTSS supports MPEG-4, MP3, and QuickTime file
formats.
You can deliver live and prerecorded media over the Internet to both Macintosh and
Windows users, or relay streamed media to other streaming servers. You can provide
unicast streaming, which sends one stream to each individual client, or multicast
streaming, which sends the stream to a group of clients.
 For more information about QTSS, refer to the QuickTime website
(www.apple.com/quicktime/products/qtss/).
 For information about managing streaming services on Mac OS X Server, see the
QuickTime Streaming Server administration guide.
Two QuickTime applications that come with Mac OS X Server help you prepare content
for streaming:
 QTSS Publisher lets you upload content to the streaming server and prepare it for
delivery. It provides these key features: creation and management of playlists,
generation of content directory websites, and editing of content annotations.
The QuickTime Streaming Server administration guide describes how to use QTSS
Publisher.
 QuickTime Broadcaster lets you produce a live event. QuickTime Broadcaster allows
you to stream live audio and video over the Internet. QuickTime Broadcaster provides
preset broadcast settings and the ability to create custom settings. Built on top of
the QuickTime architecture, QuickTime Broadcaster enables you to produce a live
event using most codecs that QuickTime supports.
