Supplied parameters
The application supplies the following parameters:
- opcode
AP_DEFINE_RTP_TUNING- path_switch_attempts
- Number of path switch attempts to set on new RTP connections. Specify
a value in the range 1-255. If you specify
0(zero), CS Linux uses the default value of 6. - short_req_retry_limit
- Number of times a Status Request is sent before CS Linux determines
that an RTP connection is disconnected and starts Path Switch processing.
Specify a value in the range 1-255. If you specify
0(zero), CS Linux uses the default value of 6. - path_switch_times
- Length of time in seconds for which CS Linux attempts to path switch
a disconnected RTP connection. This parameter is specified as four separate
time limits for each of the valid transmission priorities in order:
AP_LOW,AP_MEDIUM,AP_HIGH, andAP_NETWORK. Each of these must be in the range 1-65535. The value you specify for each transmission priority must not exceed the value for any lower transmission priority.If you specify
0(zero) for any of these values, CS Linux uses the corresponding default value as follows:- 480 seconds (8 minutes) for
AP_LOW - 240 seconds (4 minutes) for
AP_MEDIUM - 120 seconds (2 minutes) for
AP_HIGH - 60 seconds (1 minute) for
AP_NETWORK
- 480 seconds (8 minutes) for
- refifo_cap
- The RTP protocol uses a timer called the Re-FIFO Timer. The value of
this timer is calculated as part of the protocol, but this parameter specifies
a maximum value in milliseconds beyond which the timer cannot increase. In
some situations, setting this maximum value can improve performance. Setting
a value of 0 (zero) means that the timer is not limited and can take any value
calculated by the protocol.
The default value for this parameter is 4000 milliseconds, with a minimum value of 5 milliseconds. If you specify a value in the range 1-4, the value of 5 will be used.
- srt_cap
- The RTP protocol uses a timer called the Short Request Timer. The value
of this timer is calculated as part of the protocol, but this parameter specifies
a maximum value in milliseconds beyond which the timer cannot increase. In
some situations, setting this maximum value can improve performance. Setting
a value of 0 (zero) means that the timer is not limited and can take any value
calculated by the protocol.
The default value for this parameter is 8000 milliseconds, with a minimum value of 5 milliseconds. If you specify a value in the range 1-4, the value of 5 will be used.
- path_switch_delay
- Minimum delay in seconds before a path switch occurs. Specifying a delay
avoids unnecessary path switch attempts caused by transient delays in network
traffic, in particular when there is no other route available.
Specify a value in the range 0-65535. The default value is zero, indicating that a path switch attempt can occur as soon as the protocol indicates it is required.
