Novell Documentation: Volera Excelerator 2.3 - Transparent/L4 RTSP Streaming Proxy

Transparent/L4 RTSP Streaming Proxy

IMPORTANT: If your network has both QuickTime and Real RTSP traffic, you must use the L7 switch option. For more information, see Transparent/L7 Streaming Proxy.

Key Functionality

An L4 switch on the same network as the client workstation intercepts media player requests from the client and sends them to the appliance. The transparent streaming proxy service processes the QuickTime requests for the players.

Benefits of Transparent RTSP Streaming Proxy with an L4 Switch

Assuming the default streaming transport settings 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.

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.	The choices you have depend on whether the players on your network will use HTTP tunneling or UDP, RTSP.
Set up transparent streaming proxy services on the appliance	In the browser-based tool, click Cache > click Media Cache > Transparent > 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 35. 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 L4 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 port 554 traffic to a transparent proxy address on the appliance.	See B in Figure 35.
Set up players	Assuming the default player configuration settings have not been changed, transparent L4 RTSP 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.
