The value of this attribute determines the method
through which buffering resources are allocated to
ports sharing a pool of buffers.
The buffering resources associated with a series
of ports are finite. This buffer pool may be
statistically allocated to the individual ports
sharing the pool or they may be allocated such that
the traffic pattern dictates which ports temporarily
consume the majority of the buffers.
The value of this attribute determines the level
of buffer sharing or over-allocation that can take
place among ports sharing a buffer pool. Higher
levels of over-allocation increase the likelyhood
(under heavy load) of a relatively few number of
ports consuming all the buffers in a pool, causing
packets to be dropped on other ports due to buffer
starvation.
A value of 'minimumOverAllocation(1)' indicates
that only a small amount of resource sharing is
allowed. Greater resource sharing is allowed if the
value of this attribute is 'mediumOverAllocation(2)'
and the chance of over-allocation occurring is
maximized by the specifying that 'maximumOverAllocation(3)'
is desired.
In lossless mode, the buffer allocation and thresholds
are such that pause frames are generated to the endstations
prior to frames being discarded due to lack of available
buffers, allowing the end stattions to back off. This
mode allows for lossless behavior at the expense of throughput.
The value of this attribute is consulted when
the system is initialized. Changing the value of
this attribute will therefore not take effect
until after the system is restarted.
