Service Level Agreement (SLA) Measurement
Another aspect of the Frame Relay service that often needs to be tested is
provisioning as defined by the CIR (Committed Information Rate). Figure 9
depicts a typical SLA measurement.
Note: This measurement is sometimes called Service Level Agreement (SLA)
testing or Service Level Definitions (see the Frame Relay Forum FRF.13
implementation agreement).

• The Agilent Advisor performs CIR monitoring for Frame Relay activity in real
time. The analyzer provides useful customer information such as:
• Statistical traffic activity per DLCI in graphical and tabular form
comparison of real traffic activity per DLCI against a fixed CIR value CIR
• Statistics in bits, frames and percentage per DLCI for:
-Non discardable traffic DE=0
-Below the Bc (Committed Burst).
-Discard Eligible traffic DE=1
-EIR (Excess Information Rate) Statistics in bits per second, frames per
second, and percentage per DLCI for:
-Traffic below Bc (CIR)
-Traffic above the Bc, but below the sum of Bc+Be.
-Traffic above the sum of Bc+Be.
• Ability to modify the Bc and Be parameters in post processing mode to play
different CIR scenarios.
•Store statistics for further analysis in the Agilent Reporter.
