Port Numbers

Photon Cloud

In most cases you don't have to think about port numbers, as the client SDKs use a default port to reach the Photon Cloud Name Servers.

Every time a Photon server forwards a client to another server, the assigned address includes the port. This means that the port number of the Name Server is the most important one as this is not fetched.

Port numbers are specific per transport protocol and often per server type. For reference, the table below lists commonly used ports for Photon. These are available on the Photon Cloud.
