(RTMP). In a typical scenario, the Flash client is delivered to Flash Player by a web server

over HTTP. The Flash client then establishes a persistent connection to Flash

Communication Server using RTMP, allowing for an uninterrupted data stream to flow

between client and server [4]. The RTMP protocol of communication for Streaming media

is shown in Fig. 3.

Figure 3 flash media server provides a RTMP protocol of communication for

Streaming media for client.

4.2 RTMP

Real-Time Messaging Protocol (RTMP) is a protocol for client-server communication. It

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 Flash Player client, but can also be used for general remote procedure

calls (RPC). RTMP is basically a TCP/IP protocol designed for high-performance

transmission of audio, video, and data messages [4].

4.3 Client-Sever connection Flow

When the client connects to the server, the server calls application start method to run.

Next, the server-side will make and hold connection. The logic in this method determines

whether to accept or reject the connection. Back on the client side, the on status handler is

called to report whether the connection was accepted or rejected. When the client closes the

connection, the server-side disconnects and closes session [4]. The

connection flow

between clients with server is shown in Fig. 4.
