Legacy version!
This is documentation for a legacy version of Quickstream! If you want to read documentation of the newest version of Quickstream click here.
Example use cases¶
This documentation page contains example use cases with configurations for various scenarios.
High availability with two multicast input and output¶
This case is used by many Quickstream clients. It allows to send data trough Internet fully redundantly. It requires:
- Two independent UDP MPEG-TS multicast sources.
- Two Quickstream sender nodes.
- Two Quickstream receiver nodes.
- One or more UDP MPEG-TS receivers. They should support multicast main/backup configuration.
This scenario protects you against:
- Source loss
- Sender Node loss
- Receiver Node loss
It is recommended to use separate network providers for main and backup Nodes. Unless your network has some kind of redundancy like BGP routing.
Sources on sender side¶
Starting with the sender side. Let's assume that you have two independent UDP multicast MPEG-TS streams. Those streams could be from hardware encoder, playout, video mixer, etc. For example, the main multicast is udp://233.252.0.1:1234 and the backup multicast is udp://233.252.0.2:1234.
Now you need to configure four SRT connections on two Quickstream Nodes. Documentation on how to install and how to configure is available in other chapters of documentation.
SRT Connection on the sender side¶
Each connection has main and backup input and two direct outputs.
Configuration on main sender Quickstream Node¶
| Input/Output | Type | Connection |
|---|---|---|
| Main Input | UDP | 233.252.0.1:1234 |
| Backup Input | UDP | 233.252.0.2:1234 |
| Output 1 | SRT Listener | 192.0.2.2:5000 |
| Output 2 | SRT Listener | 192.0.2.2:6000 |
Configuration on backup sender Quickstream Node¶
| Input/Output | Type | Connection |
|---|---|---|
| Main Input | UDP | 233.252.0.2:1234 |
| Backup Input | UDP | 233.252.0.1:1234 |
| Output 1 | SRT Listener | 192.0.2.3:5000 |
| Output 2 | SRT Listener | 192.0.2.3:6000 |
SRT Connection on the receiver side¶
Each connection has main and backup input and one direct output.
Configuration on main receiver Quickstream Node¶
| Input/Output | Type | Connection |
|---|---|---|
| Main Input | SRT Listener | 192.0.2.2:5000 |
| Backup Input | SRT Listener | 192.0.2.3:5000 |
| Output 1 | UDP | 233.252.0.1:1234 |
Configuration on backup receiver Quickstream Node¶
| Input/Output | Type | Connection |
|---|---|---|
| Main Input | SRT Caller | 192.0.2.3:6000 |
| Backup Input | SRT Caller | 192.0.2.2:6000 |
| Output 1 | UDP | 233.252.0.2:1234 |
Outputs on receiver side¶
On the receiver side, we configured only one output per channel because there is no redundancy in multicast unless you configure source-specific multicast. If we configure two multicast streams with the same destination IP address and destination port they would interfere with each other. Simply it would not work.
You can configure your receivers to use those two multicast or manually switch between them.
