Object
table
A table of the extended package objects for queue management. 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 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. The format of the REPORT message, The 'Queue report' field reports the occupancy of each uplink transmission queue. The number of queue sets defines the number of the reported sets, as would be explained in the description of the ExtPkgQueueSetsTable table. For each set the report bitmap defines which queue is 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 Queue table has a variable size which is limited by the ExtPkgObjectReportMaximumNumQueues object as an ONU can have fewer queues to report. The entries in the table are control and status indication objects for managing the queues of an EPON interface which are gathered in an extended package as an addition to the objects which are based on the [802.3ah] attributes. Each object has a row for every virtual link and for every queue in the report. 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 ExtPkgObjectReportMaximumNumQueues.
