Attribute Meaning
Hi Priority Channel
See
• High-priority Bandwidth on page 156
• Configuration Source on page 62
Hi Priority Uplink
CIR
This field indicates the minimum rate at which high priority traffic
is sent over the uplink (unless CIR is oversubscribed or RF link
quality is degraded).
• Committed Information Rate (CIR) on page 155
• Setting the Configuration Source on page 159
Hi Priority
Downlink CIR
This field indicates the minimum rate at which high priority traffic
is sent over the downlink (unless CIR is oversubscribed or RF link
quality is degraded).
• Committed Information Rate (CIR) on page 155
• Setting the Configuration Source on page 159
Priority Precedence Allows operator to decide if 802.1p or DiffServ priority bits must
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. This
parameter, when enabled, can be particularly useful when
running bi-direction FTP sessions over the link. If a link is
primarily used for video surveillance, it is recommended to
configure this parameter to “Disabled”.
