Novell Documentation: Volera Excelerator 2.3 - Transparent/L7 Streaming Proxy

Transparent/L7 Streaming Proxy

IMPORTANT: If your network has both QuickTime and Real RTSP traffic, you must use this option for any transparent streaming services you create.

Key Functionality

An L7 switch on the same network as the client workstation intercepts media player requests from the client, identifies which requests are for QuickTime content, and sends only those requests to the appliance. (Other streaming media requests are sent to the target origin streaming server.) The transparent streaming proxy service processes the QuickTime requests for the players.

How Transparent Streaming Proxy Works with an L7 Switch

Benefits of Transparent Streaming Proxy with an L7 Switch

Assuming the default streaming transport settings (UDP, RTSP) have not been changed, transparent streaming proxy doesn't require player configuration.

After the switch and the appliance have been configured, proxy services are transparent to the player.

Setting Up Transparent Streaming Proxy with an L7 Switch

Figure 33 provides a visual map for the information in this section.

To	Do This	Notes
Ensure your basic network configuration is complete	See Basic Network Configuration Setup.
Set up the appliance to work around firewall limitations	For guidelines and more information, see Getting QuickTime Streaming Content Through Firewalls.
Set up transparent streaming proxy services on the appliance	In the browser-based tool, click Cache > Media Cache > Forward > Enable. Type a name for the transparent streaming proxy service. Ensure the Port field has 554 as its value. Click OK. Click Apply.	See A in Figure 33. If you enable logging, log files for the transparent streaming service will have the same name as the streaming service. For more information, see Client Accelerator Tab and Transparent Streaming Service Dialog Box (MMS).
Set up your L7 switch to route QuickTime player requests (port 554 traffic) to the appliance	Referring to the documentation for your switch, configure a support policy to redirect all port 554 traffic for URLs with .MOV extensions to a transparent proxy address on the appliance.	See B in Figure 33.
Set up players	Assuming the default player configuration settings have not been changed, transparent L7 streaming proxy doesn't require player configuration.	Streaming transport settings should be UDP, RTSP. Streaming proxy settings should not be enabled for an RTSP proxy server.
