RealServer protocols


Supported protocols


The RealServer supports three protocols.





Choosing a protocol


The protocol is determined by the type of media you are streaming and to some extent on the client's network configuration. Using the correct protocol ensures that the media will be streamed as quickly as possible. Using the wrong protocol can result in poor streaming quality.


RTSP is the best protocol for media created with RealSystem G2 tools. It supports many media styles and is open standard. Older (legacy) media developed with RealSystems 5.0 and earlier should use the PNA protocol. HTTP can be used if the client is located behind a firewall and cannot be reached by RTSP and PNA.
