Relay Nodes


Relay servers are recommended for the use case of one (or a few) broadcasters to many subscribers. They are basically repeaters which boost the signal of the broadcast.

Relay nodes autoscale according to the number of edges and alarm threshold value. The maxLimit for relays nodes should be the same as for your edge servers. When you set the maxLimit for your edge servers, you should divide that by your edge connectionCapacity to determine the number of relay servers that you will need, and then set that as the maxLimit for your relays.

Example: This is a one to many scenario, but it's for a large event. One broadcaster/one stream, but over 1,000,000 subscribers.

  • origin server connectionCapacity set to 50.
  • edge server connectionCapacity set to 400.
  • Given the connection capacity of the edges, we would need 2,500 edge servers to support 1,000,000 subscribers. 2,500/400=6.25, so the maxLimit for the relay nodes can be set to 7.
