Direct Stream Failover (DSF) is an optional service for clients who wish to provide a source URL that can be used as a last resort failover. This failover source can be used in addition to the regular audio source(s) which may already include dual encoders in High Availability mode. The DSF source can be the same audio signal coming from another CDN, or a different audio signal coming from any supported live source, including another Triton-based station.
Typically, this service would apply to the following use cases:
As a last-resort backup stream in the unlikely event that both of a station’s Station Manager HA streams go down.
As a redundant HA backup stream for stations that are already using SST as their streaming source.
In either case, the DSF pull source is set up but not actually streaming; streaming only kicks in when triggered by a failure of the primary source.
Direct Stream Failover (DSF) is not intended as a replacement or an alternative to High Availability mode for Station Manager; rather it is an optional stream backup of last resort. For non-Station Manager setups, it can be used as an affordable way to achieve “HA-like” redundancy.
Details
To enable DSF, speak with your Triton Digital Customer Success Manager or Solutions Specialist. They will provide assistance in setting up your redundant pull source and will enable it as a DSF on the Triton network.
Requirements
The DSF pull source must be functional and reliable, and must conform to the SST setups described in Server-side Transcoding (SST).
You must provide your DSF’s URL to your Triton Digital Solutions Specialist, who will help you test the system to ensure it works correctly.
