Real Time Messaging Protocol

From Wikipedia, the free encyclopedia

Real Time Messaging Protocol (RTMP) Is a proprietary protocol developed by Adobe Systems (formerly developed by Macromedia) that is primarily used with Macromedia Flash Media Server to stream audio and video over the internet to the Adobe Flash Player client, but can also be used for general remote procedure calls (RPC).

The protocol is being reverse engineered by an open source project (Red5 server).

Flex Data Services also uses RTMP.

WebORB is an alternative to FDS for .NET.

The default connection port is 1935. Since many corporate networks and home firewalls block this port it is advised to stream via HTTP, port 80.

However, depending on the application, this may not be an acceptable option. One of the primary benefits of using this protocol for carrying your server requests is the ability to implement server push messaging with minimal latency.
