Throughput Monitor
UNDERLOAD TRIGGER NUMBER
The number of samples within the window that must be below the next lowest target capacity for
the UNDERLOAD condition to occur.
U
NDERLOAD WINDOW SIZE
The number of sample periods (up to 32) that you should use as the sliding window.
I
DLE TRIGGER NUMBER
The number of samples within the window that must be below the specified utilization for the
IDLE condition to occur.
I
DLE WINDOW SIZE
The number of sample periods (up to 32) that you should use as the sliding window.
I
DLE PERCENT UTILIZATION
The percentage of available bandwidth on the last connection that traffic samples must fall below
for the connection to be considered IDLE.
Note: The system monitors for the IDLE condition when only one connection to a site exists, and
that connection is a switched connection.
THROUGHPUT MONITOR BACKGROUND INFORMATION
A powerful feature of the CyberSWITCH is its ability to add and drop calls depending on the
amount of WAN traffic. If no information is being sent, the call will be terminated. The system will
also make additional calls to a site if it is determined that extra bandwidth is needed.
The Bandwidth Management feature works by sampling the amount of data that is transmitted and
received on the connections between two units. Each sample is compared to the levels associated
with the different conditions. The results of these comparisons are kept in a sliding window. The
window size, number of samples that trigger an event, and sampling frequency are configurable.
The default Throughput Monitor configuration will work for initial installation. These parameters
can be changed to better match the bandwidth needs of your location.
Correctly tuning these parameters is important in order to eliminate unnecessary data calls. The
default value for the sample rate is a 5 second sample period. The following chart provides the
default values for the remaining throughput monitoring parameters.
Note: For adding calls, these parameters only apply to calls initiated by the system.
