WMS Guard

Contents

Overview

Windows Media Services (WMS) enables you to stream multimedia content over networks that range from low-bandwidth, dial-up Internet connections to high-bandwidth, local area networks.

Voynex WMS Guard is WMS plug-in which extends the functionality of the WMS. With the help of the WMS Guard it is possible to

  • restrict access to the media files and live content
  • prevent hotlinking to the streaming media content
  • authorize clients against the database
  • get statistical information about streaming media

WMS Guard is extremely useful for statistics gathering and billing. It supports the following billing schemes: pay-per-time (pay-per-minute), pay-per-connection (pay-per-view), pay-per-title (pay-per-movie), Pay-per-traffic, One-on-One (exclusive access)

More then that, you can bill clients using your own custom billing scheme. Example: client purchases exclusive access to the media stream with the time restriction. This billing scheme can be implemented by writing custom authorization script.

Using WMS Guard you can easily obtain and process various statistical information on the streaming media such as: URL of the streaming content, client IP address, HTTP referrer, etc.

Voynex WMS Guard can save all statistical information, warnings and error messages in the log file.

* The referrer, or HTTP referer, identifies the address of the web page which links to it. By checking the referrer, the new page can see where the request came from. Referrer logging is used to allow websites and web servers to identify where people are visiting them from, for promotional or security purposes.

System architecture

System in general works as shown on the Conceptual scheme:

system architecture

When website visitor clicks the link to the media content (example mms://www.videoserver.net/movie.asf?ticket=123), media player connects to media server and opens stream for playing. WMS Guard is notified on this event and sends request to the web server. This request includes URL of the streaming media, client IP address and other information. Gateway sends to the plug-in the service type and number of purchased time units. Basing on the response of the gateway WMS Guard tells WMS to grant or to deny the access to the media content.

When client stops playback, media player on the client side disconnects itself from media stream. WMS Guard plug-in is notified on disconnection event and sends statistics to the gateway.

Detailed explanation of the interconnection between the plug-in and the gateway is described in Voynex WMS Guard Protocol Specification.
