This attribute specifies the shaping recoup policy for the UBR
service category. This is the policy which is used to recoup shaping
opportunities which are lost when more than one connection
schedules a cell for the same transmit opportunity. In this case, one
connection is scheduled, and the cell from the other connection is
delayed by one cell time. This attribute affects how the transmit
time is calculated for the next cell on the delayed connection. This
attribute is ignored if this service category is not shaped.
When the connection which was delayed schedules the next cell to
transmit, it may calculate the time as a difference from either the
previous actual cell transmit time, or the time when the previous
cell should have been transmitted.
Setting this attribute to maximumEfficiency results in each
connection trying to recoup or regain any delays in scheduling. The
transmit time from the next cell is calculated from the time when
the cell should originally have been sent. Cell delay variation
(CDV) occurs in this case since the cells are sent with less than the
shaping delay between them. However, in general the shaper
recovers (recoups) lost opportunities and improves efficiency.
Setting this attribute to minimumCdv results in connections not
trying to recoup or regain any delays in scheduling. The transmit
time for the next cell is calculated from the time when the previous
cell was actually transmitted. This minimizes CDV, but results in
missed cell opportunities.
This attribute does not apply to standard Vpt Vccs and basic Vpts.
