NetTime system
NetTime system
The following diagram illustrates the NetTime system. This system is required for the
Profile XP/Open SAN environment.
For the K2 storage environment there is not an exacting requirement for clock
synchronization, but you can use NetTime to keep logging entry times in sync on
Production Network machines. Client machines do not need NetTime.
Prepare NetTime
This section provides instructions for NetTime on the Profile XP/Open SAN
NewsBrowse system. On the K2 storage NewsBrowse system, the requirement for
clock synchronization is only to keep log entries matching on production network
machines. On the K2 storage NewsBrowse system, you do not need to install NetTime
on NewsBrowse clients.
NetTime keeps the system clocks on NewsBrowse machines in sync. Since the Profile
Media Servers and single-channel encoders use the house timecode feeds, the other
machines need to be kept in sync as well. On systems that control ingest and have
single-channel encoders, the primary purpose of NetTime is to keep the Ingest
Scheduler, which runs on the NewsBrowse server, and the NewsBrowse client
machines synchronized to house time. On systems that do not control ingest, NetTime
is still useful to keep clocks synchronized so that system logs can be correlated.
The following procedure uses a single-channel encoder as the Adrienne Absolute
Time Server. If your system does not control ingest and has no single-channel
encoders, you can use any machine as the Adrienne Absolute Time Server.
The single-channel encoder runs the Adrienne Absolute Time Server. NetTime clients
on the production network reference the Adrienne Absolute Time Server. A NetTime
server runs on the NewsBrowse server, which rebroadcasts the time to the client
network. NetTime clients on the client network reference the NetTime server.
