ADCD adjustment

Typically, WAN adjustment requires that the NAM Probe is able to identify and correlate the traffic on both the LAN side and the WAN side, but this is not possible in certain scenarios.

Scenarios in which such traffic correlation is not possible:

  • Non-synchronized monitoring: when the protocol used on the WAN link cannot be analyzed in the middle of a TCP stream.
  • Packet loss: when any packet lost on the LAN or WAN breaks the synchronization and correlation between LAN and WAN analysis.
  • Missing WAN link traffic: when the correlation and adjustment could not be performed due to LAN or WAN traffic availability.

As a result, WAN adjustment cannot be performed for all operations and statistics are not adjusted to represent WAN performance.

This ADCD adjustment option enables you to take the average ADCD of operations for which it was measured and apply it to operations for which the NAM Probe was not able to calculate the ADCD, provided that these operations share the same server and client.

  • Client network mask
    A mask of a client network where operations will be considered for ADCD adjustment in the event of mismatched LAN/WAN traffic.
  • Server network mask
    A mask of a server network where operations will be considered for ADCD adjustment in the event of mismatched LAN/WAN traffic.
