Virtual Server RTSP Service Configuration Menu
The following menu example is application-specific and includes only the application-specific commands. For all common commands, refer to /cfg/slb/virt <server id>/service/basic-slb Virtual Server Basic SLB Service Configuration Menu.
The objective of RTSP SLB is to intelligently switch an RTSP request, and the other media streams associated with a presentation, to a suitable RTSP server based on the configured load balancing metric. Typically, an RTSP client establishes a control connection to an RTSP server over TCP port 554 and the data flows over UDP or TCP. This port can be changed however.
Note: When you enable RTSP, Alteon performs delayed binding (dbind) and waits for the RTSP payload. In such a case, the backend connection does not open until the payload is received. Alteon reserves port 554 for RTSP. In case you are required to use port 554 as a basic-slb or disable Alteon not to delay bind for service 554, use the command, nortsp ena. This makes Alteon to act service 554 as a basic-slb or simple Layer 4 port.

Virtual Server RTSP Service Configuration Options (/cfg/slb/virt/service/rtsp) 
Command Syntax and Usage
rtspslb hash|pattern|l4hash|none
 
Specifies how to select the RTSP server, whether based on Layer 7 parameters or not.
Values:
*l4hash — Alteon performs server load balancing based on the Layer 4 hash metric.
*none — Alteon performs server load balancing based on all Layer 4 metrics.
*hash — Alteon performs hash on the URL to select a server.
*pattern — Alteon selects the server by matching strings configured per real server to the received URL.
Default: none
softgrid <enable|disable>
 
Specifies whether to enable SoftGrid load balancing.
Alteon supports load balancing tailored to the SoftGrid suite for the delivery of sequenced applications and the maintaining of persistence while applications are launched from the SoftGrid Client. Once an application is delivered to the SoftGrid Client, it can be run on the client computer.
Default: disable
nortsp <enable|disable>
 
Enables or disables RTSP SLB for DSR configuration.
