Attribute
Meaning
Sustained Downlink Data
Rate
Specify the rate at which the AP should be replenished with credits (tokens)
for transmission to this SM. This default imposes no restriction on the uplink.
See
Maximum Information Rate (MIR) Parameters on Page 2-2
Interaction of Burst Allocation and Sustained Data Rate Settings on
page 2-3
Setting the Configuration Source on page 2-6
Uplink Burst Allocation
Specify the maximum amount of data to allow this SM to transmit before
being recharged at the Sustained Uplink Data Rate with credits to transmit
more. See
Maximum Information Rate (MIR) Parameters on page 2-2
Interaction of Burst Allocation and Sustained Data Rate Settings on
page 2-3
Setting the Configuration Source on page 2-6
Downlink Burst Allocation
Specify the maximum amount of data to allow the AP to transmit to this SM
before the AP is replenished at the Sustained Downlink Data Rate with
transmission credits. See
Maximum Information Rate (MIR) Parameters on page 2-2
Interaction of Burst Allocation and Sustained Data Rate Settings on
page 2-3
Setting the Configuration Source on page 2-6
Hi Priority Channel
See
High-priority Bandwidth on page 2-4
Setting the Configuration Source on page 2-6
Priority Precedence
Allows operator to decide if 802.1p or DiffServ priority bits should be used
first when making priority decisions.
PPPoE Control Message
Priority
Operators may configure the SM to utilize the high priority channel for
PPPoE control messages. Configuring the SM in this fashion can benefit the
continuity of PPPoE connections when there are issues with PPPoE sessions
being dropped in the network. This prioritization may be configured in the
DiffServ tab in the Configuration menu of the SM.
Prioritize TCP ACK
To reduce the likelihood of TCP acknowledgement packets being dropped, set
this parameter to Enabled. This can improve throughput that the end user
perceives during transient periods of congestion on the link that is carrying
acknowledgements.
