Striim 3.9.4 / 3.9.5 documentation

Using TCP/IP instead of multicast UDP

By default, as discussed in System requirements, a Striim cluster uses multicast UDP to discover and add servers. Alternatively, you may configure a cluster manually using TCP/IP. This will have no impact on performance.

To do that, on each server in the cluster, edit striim/conf/ and set the following options:

ServerNodeAddress=<node list>

The ServerNodeAddress value is a comma-separated list of the IP addresses of all servers in the cluster, for example, ServerNodeAddress=,


The ServerNodeAddress setting must be the same on all servers in the cluster.

You must also open port 5701 for TCP on each server.

Then restart the servers, as described in Starting and stopping Striim.
