Select your availability mode

When creating a new input, selecting the availability mode allows you to control the level of resilience to failures of SRT senders, Quortex Link and SRT receivers.


What could go wrong ?


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 output, 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 2 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.


Single input stream


Single input stream


Use Single input stream 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 Single input stream with non-critical contents only. For your premium contents, consider using Dual input stream.

With Dual input stream with automatic failover, input reliability is increased, while delivering once to outputs.


For improved resiliency, we recommend the use of 2 independent Internet Service Providers to connect each SRT stream to Quortex Link.



The best protection against failure is achieved when you have the same number of receivers and transmitters.

In this case, we allow advanced configuration, via API, to create redundancy path in different availability zone.


Do not hesitate to reach out to us if you want to implement this redundancy configuration.
