Select your availability mode
When creating a new source or destination, selecting the availability mode allows you to control the level of resilience to failures of SRT senders, Quortex Link and SRT receivers.
A media streaming flow is a composed of several hardware and software components.
For Quortex Link, the flow starts from the sender device at one end of the SRT connection. Data will be streamed through the local network, then through the network of an Internet Service Provider, to the regional data center where Quortex Link has set the other end of the SRT connection. Quortex Link may then transfer over Internet to the regional data center chosen for the destination, where a SRT connection will be established to the receiver device through other ISP and local networks.
Despite using professional equipment, possibly any of those component may fail, transiently or permanently.
Availability modes provide resiliency to such failures. Quortex Link offers several availability modes, depending on the desired level of protection.
Given the large number of possible failures in a media streaming flow, many factors needs to be considered when defining a resilience policy.
Quortex Link provides several modes covering a large range of use cases.
Please reach Quortex Link for further guidance on choosing your availability mode and reaching you resilience goals.
Use Standard Availability when you can use only one SRT device. This is the most cost effective distribution architecture.
A failure of your SRT equipment, or of the network between your equipment and Quortex Link may impact the distribution of your content.
We recommend using Standard Availability with non-critical contents only. For your premium contents, consider using High Availability or Premium Availability.
Use High Availability when you can feed your source using two redundant SRT devices. This will ensure uninterrupted delivery, even in case of failure of an SRT device or the ground-to-cloud network connectivity.
We will automatically deploy a highly available infrastructure in the cloud, over two physically separate locations.
For improved resiliency, we recommend the use of 2 independent Internet Service Providers to connect each SRT stream to Quortex Link.
Use Premium Availability when you can feed your source using two redundant SRT senders, each sender delivering two separate streams. This is the most secured architecture, providing you the highest availability for your critical contents.
We will automatically deploy a highly available infrastructure in the cloud, over two physically separate locations.
The best protection against failure is achieved when the same availability mode is used for both the source and destination.
However, a destination can use a lower availability mode than its source. This is typically usefull to reduce delivery cost to less critical destinations, or if this destination doesn't have a redundant receiver.
A destination can't use an availability mode higher than its source.

Selecting different availability modes for source and destinations
The best protection against failure is achieved when the same availability mode is used for both the source and destination.
However, a destination can use a lower availability mode than its source. This is typically usefull to reduce delivery cost to less critical destinations, or if this destination doesn't have a redundant receiver.
