table
This table contains the attributes of the QoS enforce rules
present on the CMTS. 
          
These enforce rules define the criteria for identifying 
subscribers who over consume resources. This could be as 
simple as bytes transmitted over the last monitoring 
duration and checked at a rate equal to the sample rate.
          
In the sliding window concept used, the monitoring duration
is the size of the window. This window slides by an amount
that is equal to the sample rate. At every sample rate the 
bytes transmitted in the time equal to a monitoring duration 
is  checked. If this is found to be larger than the threshold
limit which is calculated by multiplying the defined average
rate by the monitoring duration per monitoring duration, 
the subscriber is flagged as over consuming.  Else the 
monitoring will continue.
          
For example let the monitoring duration be 360 minutes and
sample rate be 30 minutes. If the average rate is 2kbits/sec 
then every 30 minutes we check if the bytes transmitted in 
the last 360 minutes exceeded 5.4Mbytes bytes. If so, the 
subscriber is over consuming.
          
The enforce rule has a one to one mapping to QoS profiles 
in case of DOCSIS1.0 (and DOCSIS1.0+ modems) and to 
service class names in case of DOCSIS1.1 and 
DOCSIS2.0 modems.
          
It defines the registered QoS parameter set and an enforced 
QoS parameter set be applied if found to be violating the 
registered QoS parameter set.
The enforce rule also defines a penalty period for which
the enforced QoS parameter set will be applied. The 
registered QoS parameter set will be restored when the 
penalty period expires.
          
The monitoring can be of two types:
1) Legacy/Basic monitoring: There is only one threshold and 
   one monitoring-duration and the monitoring-duration
   can be more than one day and within a day there is no
   distinction among hours as peak or offpeak hours. An
   example would be: 
   monitoring duration   : 2 days
   Average rate          : 2kbits/sec
          
2) Peak-offPeak monitoring: A maximum of two peak durations 
   can be defined with in a day and the remaining hours are 
   treated as off-peak and the monitoring will happen during
   these offpeak hours if the offpeak duration and threhold
   are defined. The monitoring-duration and threshold for 
   all three, first peak, second peak and offpeak can be 
   different. Here, the monitoring duration for any of the 
   peaks or offpeak cannot be more than a day. An
   example when both peaks and offpeak are defined is:
   First peak:
         monitoring duration: Between 6am to 9am i.e., 3hours
         Average rate       : 2kbits/sec
   Second peak:
         monitoring duration: Between 6pm to 10pm i.e., 4hrs
         Average rate       : 3kbits/sec
   Off peak:
         Remaining hours in the day i.e.,
         12 midnight to 6:00am,
         9am to 6pm and 10pm to 12mignight.
         monitoring duration: 2 hours
         Average rate       : 1kbits/sec.
