Egress Message Throttling Configuration Set elements

Table 3-8 describes the fields on the Egress Message Throttling Configuration Sets View, Edit, and Insert pages. Data Input Notes apply only to the Insert and Edit pages; the View page is read-only.

Table 3-8 Egress Message Throttling Configuration Set Elements

Field (* indicates required field) Description Data Input Notes
* Egress Message Throttling Configuration Set Name A name that uniquely identifies the Egress Message Throttling Configuration Set.

Format: String: case-sensitive; alphanumeric and underscore (_); must contain at least one alpha; cannot begin with a digit.

Range: 1 - 32 characters

* Max Egress Message Rate

A maximum Egress Message Rate (EMR) on a connection being throttled

Note:

The EMR is calculated every 100ms by subtracting the oldest traffic count from the newest traffic count, and averaging the difference over the elapsed time between them.

Format: numeric

Range: 10 - 10000

Default: none

* Throttle Threshold Level 1 (%) Throttle Threshold Level 1. When Threshold exceeds Level 1, Congestion Level is set to 1

Format: numeric

Range: 2 - 100

Default: 100

* Abatement Threshold Level 1 (%) Abatement Threshold Level 1. When Threshold falls below Level 1, Congestion Level is set to 0.

Format: numeric

Range: 1 - 99

Default: 80

Throttle Threshold Level 2 (%) Throttle Threshold Level 2. When Threshold exceeds Level 2, Congestion Level is set to 2.

Format: numeric

Range: 4 - 100

Default: none

Abatement Threshold Level 2 (%) Abatement Threshold Level 2. When Threshold falls below Level 2, the Congestion Level is set to 1.

Format: numeric

Range: 3 - 99

Default: none

Throttle Threshold Level 3 (%) Throttle Threshold Level 3. When Threshold exceeds Level 3, Congestion Level is set to 3.

Format: numeric

Range: 6 -100

Default: none

Abatement Threshold Level 3 (%) Abatement Threshold Level 3. When Threshold falls below Level 3, the Congestion Level is set to 2.

Format: numeric

Range: 5 - 99

Default: none

* Convergence Time (msec)

The time it takes in milliseconds to converge on a per second rate. If the convergence time is less than 1000 milliseconds, the rate is Convergence Time (msec) extrapolated. If the convergence time is greater than 1000 milliseconds, the rate is averaged.

The rate convergence time is the amount of time it takes for the measured rate to converge on the actual rate.

Format: numeric

Range:
  • 250
  • 500
  • 1000
  • 2000
  • 4000

Default: 250

* Abatement Time (msec)

This value specifies the amount of time that a throttled connection's Egress Request Rate must remain below an abatement before allowing it to abate to a lower CL.

For example, if the following is true:
  • Max EMR = 1000 messages per second
  • Abatement Threshold-3 = 80% * 100=> 800 messages per second)
  • Abatement time = 500 milliseconds
  • Current Congestion Level = CL3

Then all of the message rate calculations during a contiguous 500 msec must be less than 800 MPS in order for the congestion level to be reduced from CL3 to CL2.

Format: numeric

Range: 200 - 10000

Default: 500
