Controlling Congestion for SVCs
Congestion occurs when a network device receives more frames than it can
process, or sends more frames than the transmission line can transport. When you
enable congestion control, the router receives congestion notification messages
from the SVC experiencing congestion, and drops all outbound traffic destined for
that SVC until it no longer receives congestion notifications.
When you enable congestion control, you can set the length of time during which
the router counts congestion notifications. You can also set the maximum number
of congestion notifications that the router can receive during this time period. If
the router receives this number of congestion notifications within the time period
you specify, it stops transmitting data. The router resumes transmission when it
stops receiving congestion notifications.
If you enable congestion control, all SVCs on the interface use congestion control
and the values you specify for the congestion timer and congestion counter.
However, you can configure SVCs individually at the service level. In this case,
you can either disable congestion for an individual SVC, or select other
congestion control parameters for that SVC.
