Because the Helix Universal Server delivers Windows Media, you can now take advantages of a superior technology that uniquely ensures zero points of failure as follows:
Helix Servers automatically route player requests to back-up servers in the event of a service failures or unplanned outages
Redundant live sources can be treated as one in the event of source failure
Redundant network paths can be configured to circumvent single points of failure in the distribution chain
With the Autorestart feature, a failed process will automatically be restarted without the need for administrator intervention
RealPlayer will automatically and seamlessly connect to an alternative server should a failure occur with the primary stream.
That's what a reliable, end-to-end system does.
None of these features are supported in the Windows Media server.
How important is it that your broadcast actually reaches its audience?
