To combat aggressive subscribers, additional rate limits can be defined on usage.
These limits can be defined for Inbound, Outbound, and Half-Duplex traffic and
for Normal and Congested conditions.
Dyband has enabled a unique approach to combating aggressive users called a
Rate Ramp. The Dyband Shaper enables you to set an Acceptable Average
Rate each MP, and when usage exceeds that rate, to progressively reduce the
rate limit over time using a rate ramp. At the same time, two other policy settings
(Minimum Priority and Maximum Latency) may also be ramped under Congested Conditions,
either to mitigate or intensify the impact of the reduced rate limit.
The overall effect of Rate Ramps is that the aggressive subscriber's impact
on the entire network is minimized, enabling other users' traffic to pass, while
at the same time revealing to the aggressive subscriber a gradual reduction
in bandwidth as opposed to a sudden halt or dramatic reduction in traffic flow.
