If you have enabled an authentication profile (other than a basic profile) on a service that is handling HTTP-tunneled MMS or QuickTime object requests, the object requests will fail.
Excelerator handles HTTP-tunneled objects using the same system parameters as it uses for HTTP objects. Therefore, the authentication method specified for the HTTP service will also be used for HTTP-tunneled requests.
However, media players support only basic authentication. Therefore, if a non-basic authentication profile is specified for the service, requests for HTTP-tunneled objects will fail.
The browser-based management tool allows multiple streaming services of the same type on the same port.
For Apple QuickTime RTSP and Windows Media services, you should ensure that each streaming service is set to use a unique port.
In contrast, for Real Media services, you should ensure that all RealProxy services use the same port and that this port is not used by any other non-RealProxy service.
For example, if an Apple QuickTime RTSP streaming service is set to use port 554, then all Real services must be configured to use a port other than 554, such as 555.
The base Excelerator RTSP transparent service attempts to cache both QuickTime and Real traffic. However, the Real content will not play.
If you have both QuickTime RTSP and Real RTSP traffic on your network, you need to purchase the Media Excelerator for RealProxy to handle the Real traffic and configure the Real services to use a port that is not used by another service type. For more information on using ports with streaming services, see Port Considerations.
Applying changes in the browser-based management tool may disrupt any cache streams currently being accessed by network users.
Excelerator 2.x's SMC parameters default settings are for unlimited network bandwidth.
You must set the Maximum Downstream Bandwidth parameter to match your network. Otherwise, Excelerator can serve streaming media output that exceeds the capacity of your network hardware, including the appliance's network cards.
When this happens, the resulting back log can result in lost packets and other more severe problems, including the Excelerator system crashing.
For information on this and other SMC tuning parameters, see "Streaming Management Configuration Dialog Box" in the Volera Excelerator 2.3 Administration Guide.
