Explains the concept of delays in network interfaces and circuits, including how delay is represented, configured, and why asymmetric delay matters.
Delay is a property that
-
indicates the time it takes for a data packet to travel from the source to the destination across a network path
-
can be set in the Add or Edit page of the Interfaces and Circuits, and
-
is indicated by the Delay column in the Interfaces and Circuit tables.
Asymmetric delay
Starting with the 7.2.0 release, Cisco Crosswork Planning allows you to set different delay values on interfaces associated with circuits. In other words, each interface in a circuit can have its own delay metric, rather than a single delay value for the circuit as a whole.
Columns related to delay
There are two columns related to Delay in the Interfaces and Circuits tables.
-
Delay: One-way transmission latency in milliseconds (ms).
-
Delay sim: (Derived) Simulated one-way transmission latency. All Cisco Crosswork Planning delay calculations that use the L3 circuit delay, such as Metric optimization, use the Delay sim value.
