This attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the transmit data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
transmit packet-wise functions are Early Packet Discard (EPD) and
Partial Packet Discard (PPD).
EPD allows the connection to discard an entire frame once the
transmit queue has reached the EPD threshold. EPD increases the
'goodput' of a link, since discarding an entire frame means that
some queue capacity is guarded for some other frame which is
already partially transmitted. All cells of the frame are discarded
from the Beginning of Message (BOM) cell up to and including the
End of Message (EOM) cell.
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded.
All cells are discarded up to but not including the EOM cell. The
PPD function increases the 'goodput' of the link, since cells which
are only going to be discarded at the AAL5 reassembly point are
not transmitted.
On CQC-based ATM cards, the packet-wise discard functions are
PPD and EPD. PPD is available at VCC cell-transfer points. PPD is
not applicable at frame-cell conversion points, and is not applicable
for Vpcs. PPD is configured by this attribute. Packet-wise discard
should only be enabled for connections carrying AAL5
segmentation traffic. Setting the value to enabled for any other
traffic type may result in all traffic being discarded. On CQC-based
ATM FPs, EPD is automatically enabled at frame-to-cell conversion
points, independent of the setting of this attribute.
On CQC-based ATM cards, at a permanent VCC connection
endpoint, this attribute is not applicable and is ignored. If AAL5
segmentation and reassembly has been requested, PPD and Early
Packet Discard (EPD) are automatically enabled.
On ATM IP cards, packet-wise discard functions include EPD and
PPD. PPD and EPD apply to individual VCCs and VCCs within
VPCs at all connection points, including tandem VPC connections.
Both PPD and EPD are controlled by this attribute. This attribute
may safely be set to enabled for any connection (Vcc or Vpc) on
ATM IP FPs since they have the ability to automatically detect
AAL5-segmented traffic on a connection, and only enable packet-
wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to transmit traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to transmit traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the backward direction. When this
attribute is set to disabled, backward frame discard is not requested
in the SPVC call setup.
The transmit packet-wise discard functions that are active are
visible in the Vcc/Vpc Tm txPacketWiseDiscard operational
attribute.
