Primary features of Release 2.4
- VUE N:1 Redundancy Clusters
In an N:1 redundancy cluster the standby server automatically synchronizes the configuration with all the active servers within the redundancy cluster. The standby server can store the configurations of up to 10 active servers. The standby server does not assume the configuration of any particular active server until failover time, when it applies the failed active server's configuration and goes operational.
A single standby server continuously exchanges Heartbeat (HB) messages with all the active servers present in the RC using either one or two separate heartbeat network paths. These HB messages are exchanged every 100 milliseconds.
Any change in configuration on one of the active servers automatically propagates to the standby server within one second.
- Transport Stream Redundancy
Transport Stream Redundancy allows the specification of an alternate Multicast transport stream input, on the same VUE application server. The secondary transport stream is automatically switched to in the event that the primary input fails. This can be configured with SPTS and MPTS stream inputs.
A TS that is part of a TSR pair is considered failed if its bit rate drops to 0 Mbps or there is loss of both bonded NICs used for interface redundancy. If any of these conditions are met, the failover happens automatically. Failovers can be forced or suspended.
- Configuration of TSID values for Broadcast Service Groups
- A default Transport Stream ID (TSID) value can be specified for Broadcast Service Groups. This default value will be applied to all Transport Streams in the Broadcast Service Group. The TSID value can be overridden on a per Transport Stream basis. The default TSID value is zero.
- Reuse PAT TSID Support
- When enabled, this feature configures the VUE to use the TSID values that are carried in the PAT for a PassThru or AutoMap type input stream. When disabled, it configures the VUE to use the TSID values configured by VTM. Enabling/Disabling the "Reuse PAT TSID" configuration can be done on a per Output Transport Stream basis.
