Administering Your Server 55
Anything that can be addressed using a URL can be a network service—for example, file
servers and WebDAV servers. When a service is added to your network, the service uses SLP
to register itself on the network; you don’t need to configure it manually. When a client
computer needs to locate a network service, it uses SLP to look for services of that type. All
registered services that match the client computer’s request are displayed for the user, who
then can choose which one to use.
SLP Directory Agent (DA) is an improvement on basic SLP, providing a centralized repository
for registered network services. You can set up a DA to keep track of services for one or more
scopes (groups of services). When a client computer looks for network services, the DA for
the scope in which the client computer is connected responds with a list of available network
services. Because a client computer only needs to look locally for services, network traffic is
kept to a minimum and users can connect to network services more quickly.
See Chapter 16, “SLP DA Service,” for information about this service.
QuickTime Streaming Service
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 Web site:
www.apple.com/quicktime/products/qtss/
You can use QuickTime Broadcaster in conjunction with QTSS when you want to produce a
live event. QuickTime Broadcaster allows you to stream live audio and video over the
Internet. QuickTime Broadcaster meets the needs of both beginners and professionals by
providing 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.
When teamed with QuickTime Streaming Server or Darwin Streaming Server, QuickTime
Broadcaster can produce a live event for delivery to an audience of any size, from an
individual to a large global audience.
