Rate
[SBCAdmissionControl_
Rate]
Defines the rate (in seconds) at which tokens are added to the token
bucket per second (i.e., token rate).
The default is 0 (i.e., unlimited rate).
Notes:
You must first configure the Maximum Burst parameter (see below)
before configuring the Rate parameter.
The token bucket feature is per IP Group, SRD, SIP request type, and
SIP request direction.
Maximum Burst
[SBCAdmissionControl_
MaxBurst]
Defines the maximum number of tokens (SIP dialogs) that the bucket can
hold. The device only accepts a SIP dialog if a token exists in the bucket.
Once the SIP dialog is accepted, a token is removed from the bucket. If a
SIP dialog is received by the device and the token bucket is empty, then
the device rejects the SIP dialog. Alternatively, if the bucket is full, for
example, 100 tokens, and 101 SIP dialogs arrive (before another token is
added to the bucket, i.e., faster than that defined in the Rate field), then
the device accepts the first 100 SIP dialogs and rejects the last one.
Dropped requests are replied with the SIP 480 “Temporarily Unavailable”
response. Dropped requests are not counted in the bucket.
The default is 0 (i.e., unlimited SIP dialogs).
Note: The token bucket feature is per IP Group, SIP Interface, SRD, SIP
request type, and SIP request direction.
