MIR Data Entry Checking
Uplink and downlink MIR is enforced as shown in Figure 56.
In these figures,
entry
refers to the setting in the data rate parameter, not the burst
allocation parameter.
Figure 56 Uplink and downlink rate caps adjusted to apply aggregate cap
For example, in the SM, if you set the Sustained Uplink Data Rate parameter to 2,000
kbps and the Sustained Downlink Data Rate parameter to 10,000 kbps, then the uplink
and downlink MIR that is enforced for the SM can be calculated as shown in Figure 57.
Figure 57 Uplink and downlink rate cap adjustment example
In this example case, the derived 1,167-kbps uplink and 5,833-kbps downlink MIR sum to
the fixed 7,000-kbps aggregate cap of the SM.
Committed Information Rate (CIR)
The Committed Information Rate (CIR) capability feature enables the service provider to
guarantee to any subscriber that bandwidth will never decrease to below a specified
minimum unless CIR is oversubscribed or RF conditions are degraded. CIR is
oversubscribed when there is not enough available bandwidth to support CIR configuration
for all subscribers. In this condition, SMs which are configured with a nonzero CIR will all
operate at the maximum data rate supported by the link (subject to Maximum Information
Rate and Burst Rate/Allocations). SMs which are configured with a CIR of 0 kbps will not
transmit until CIR-configured SMs have completed transmission. CIR may be configured
independently for high priority traffic and for low priority traffic.
CIR parameters may be configured in the following ways:
• Web-based management GUI
• SNMP
• Authentication Server (RADIUS) - when a SM successfully registers and authenticates,
CIR information is retrieved from the RADIUS server.
uplink cap enforced =
uplink entry x aggregate cap for the SM
uplink entry + downlink entry
downlink cap enforced =
downlink entry x aggregate cap for the SM
uplink entry + downlink entry
uplink c ap enforced =
2,000 kbps x 7,000 kbps
2,000 kbps + 10,000 kbps
= 1,167 kbps
downlink cap enforced =
10,000 kbps x 7,000 kbps
2,000 kbps + 10,000 kbps
= 5,833 kbps
