dot3ExtPkgQueueSetsTable

A table of Extended package objects used for the management of the queue_sets. 
Entries are control and status indication objects of an EPON interface which 
are gathered in an extended package as an addition to the objects based on 
the [802.3ah] attributes. The objects in this table are specific for the 
queue_sets which are reported in the MPCP REPORT message as defined in 
[802.3ah] clause 64. The [802.3ah] MPCP defines a report message of the 
occupancy of the transmit queues for the feedback BW request from the ONUs. 
These queues serve the uplink transmission of the ONU and data is gathered 
there until the ONU is granted for transmission. The management table of 
the queues_sets is added here mainly to control the reporting and to gather 
some statistics of their operation. This table is not duplicating existing 
management objects of bridging queues, specified in [802.1d], since the 
existence of a dedicated transmit queuing mechanism is implied in the 
[802.3ah] and the ONU may be a device which is not a bridge, with embedded 
bridging queues. As can be seen from the message format, the ONU interface 
reports of the status of up to 8 queues and it can report in a single MPCP 
REPORT message of a few sets of queues. The number of queue_sets defines 
the number of the reported sets, and it can reach up to a value of 8. It 
means that a ONU can hold a variable number of sets between 0 to 7. The 
dot3ExtPkgQueueSetsTable table has a variable queue_set size which is 
limited by the dot3ExtPkgObjectReportMaximumNumThreshold object as an ONU 
can have fewer queue_sets to report. The 'Queue report' field reports the 
occupancy of each uplink transmission queue. The queue_sets can be used to 
report the occupancy of the queues in a few levels as to allow granting, 
in an accurate manner, of only part of the data available in the queues. 
A Threshold is defined for each queue_set to define the level of the queue 
which is counted for the report of the occupancy. The threshold is reflected 
in the queue_set table by the dot3ExtPkgObjectReportThreshold object. For 
each queue set, the report bitmap defines which queues are present in the 
report, meaning that although the MPCP REPORT message can report of up to 
8 queues in a REPORT message, the actual number is flexible. The 
dot3ExtPkgQueueSetsTable table has a variable queue size which is limited 
by the dot3ExtPkgObjectReportMaximumNumQueues object as an ONU can have 
fewer queues to report. Each object has a row for every virtual link, for 
each queue in the report and for each queue_set in the queue. The LLID 
field, as defined in the [802.3ah] is a 2bytes register (15bits field and 
a broadcast bit) limiting the number of virtual links to 32768. Typically 
the number of expected virtual links in a PON is like the number of ONUs, 
which is 32-64, plus an additional entry for broadcast LLID (with a value 
of 0xffff). The number of queues is between 0 and 7 and limited by 
dot3ExtPkgObjectReportMaximumNumQueues. The number of queues_sets is 
between 0 and 7 and limited by dot3ExtPkgObjectReportMaximumNumThreshold.
