These basic verification techniques are general approaches to WAN analysis and
troubleshooting that are accepted in the industry because of their systematic
appeal and proven effectiveness.

CIR is one of the most important features for Frame Relay Management. CIR is
a contract between the Service Provider and an User. This contract allows both
parties to exchange information under controlled traffic conditions. CIR is the
rate expressed in bits per second (bit/s) at which the network agrees to transfer
information under normal conditions. This rate is measured over the measure-
ment interval Tc. The default value of Tc is 1 second.

The Agilent Advisor performs CIR monitoring of 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 utilization in the Internet Reporter
