Module 7: Design Windows Media Services
Infrastructure
• Design Windows Media Services for live streaming
• Windows Media Services for on-demand content
• Improving performance for on-demand content
• Monitoring Windows Media Services
Lesson 1: Design Windows Media Services for Live
Streaming
• Overview Windows Media Services for Windows
Server 2008
• Standard edition vs. Enterprise edition
• Backwards compatibility with Windows Media
Services for Windows Server 2003
• Live streaming capabilities
• Planning for multi site deployments

Standard edition vs. Enterprise edition
Windows Media Services for Windows Server 2008
Enterprise Edition includes
• Multicast capability
• IGMPv3 support
• Caching and multi-tasking (play while archiving)
• Advanced FF/RW support
Backwards compatibility with Windows Media
Services for Windows Server 2003
• Full compatibility with existing content and streams
• WMS for Windows Server 2008 requires Server 2008
• If upgrading an existing installation, modify registry
Live streaming capabilities
Scenario
Origin
Intranet (some data
loss acceptable)
WMS 9 or later via UDP
Rtsp://server/publishing_point
Intranet (no data loss
acceptable)
WMS 9 or later via TCP
Rtspt://server/publishing_point
Servers separated by
firewall
WMS 9 or later via http
http://server/publishing_point
Rebroadcast multicast
stream to unicast
network segment
WMS 9 or later via MCast
MCast://%systemdrive%\Wmpub\Wmroot\file.
nsc
HTTP and MCast can also be used to connect to Media Services 4.1.
Planning for multi site deployments
Required Network Capacity
= Content bit rate x estimated number of clients
Multicast Streaming
Increases the capacity of a stream
Enable Multiple Bit Rate to
improve the performance of low bandwidth clients
Use IPSec for secure transfer between sites
Remote WMS
Lesson 2: Windows Media Services for ondemand content
• Design digital rights management
• Design content storage

Scenario
Origin
File server
(Share)
• Resource can run other services
Network Attached
Storage
(NAS)
• Dedicated appliance
Storage Area
Network
(SAN)
• Access using publishing point computer account
• Easy to configure
• Potentially the most expensive solution
• Higher performance with block level access
• Expandable as needed
 Increase caching performance by disabling file sharing mode

• Active Directory Lightweight Directory Services (AD
LDS)
• Dynamic Host Configuration Protocol (DHCP) Server
• DNS Server
• File Services
• Print Server
• Windows Media Services
