Connections
Connections are Flash Communication Server client connections and are what determines the number of simultaneous users that are able to utilize your FlashCom application at any one given time. 10 Connections = 10 Simultaneous Users Max.

Bandwith
Your Streaming Bandwidth is the rate at which data is passed from the client to the server and the server to the client. Smooth video and clear sound, as well as delay time are all factors determined by your Streaming Bandwidth. Higher number = better stream.

Disk Space
The Flash Communication Server gives you the ability to store objects on the server, such as chat history, recorded audio streams, and recorded video streams. The size of these files vary depending on the length of the recorded stream. If your applications permit heavy recording then you may want a plan that offers more disk space.

Bandwith Usage
When data is transferred from your FlashCom application to the client, such as streaming video and audio, the amount of bandwidth used by your account increases. Bandwidth Allowance is the amount of data transfer packaged into your account, going over this amount costs per Gigabyte depending on your service plan.
