CIR is the minimum information transfer rate that the system is committed to
transfer under normal conditions (minimum reserved traffic rate).
MIR is the maximum information rate that the system will allow for the
connection (maximum sustained traffic rate).
The CIR/MIR rate is averaged over a minimum increment of time, which is defined
by the CT parameter.
The range of CIR/MIR for all Downlink flows and for Uplink BE and NRT flows is
from 32 (the default) to 54,000 Kbps.
For Uplink ERT flows where we have the advantage of periodic allocations, the
UGI (equal to CT/2) and the range for MIR are as follows:
The uplink CIR of eRT will be set internally to the value configured for MIR
In the Downlink of ERT flows UGI has no meaning and the configuration range for
CIR and MIR is 32-54000 Kbps. However, ERT QoS offers the advantages of
higher priority and lower latency values than BE or NRT QoS.
MIR cannot be lower than CIR for the same direction.
4.6.2.6 Multiple Service Flows
The Multiple Service Flows menu enables managing Multiple Service Flows,
including the Service Rule(s) associated with each Multiple Service Flow. The
menu for a selected Multiple Service Flow (after the basic parameters are defined)
enables access to the Service Rules submenu. At least one Service Rule must be
assigned to each Multiple Service Flow, up to a maximum of four Service Rules
NRT CIR, MIR
