Approriate time interval to streaming a video file to client?

Question

I'm building a streaming video server. Now I must transfer sequence data (data packets) of a video file to client. But I don't know timer tick to transfer a data packet. If i transfer too fast, client don't have enough time to decode and display.I don't know whether it depend on Bitrate or other information of a video file ?.Video file i'm using is WMV. Protocol i'm using to streaming is Windows Media Http Streaming protocol. Programing language I'm using is C#.
 
Information of video file :
 
Audio: Windows Media Audio 48000Hz stereo 64Kbps [Raw Audio 0]
 
Video: Windows Media Video 9 320x240 24.00fps 230Kbps [Raw Video 1]
 
Whether have formular to calculate time interval to transfer data?
