The link Latency (Multilink with 2 x E1) normaly is 160ms, but some times occurs a latency peaks (1000ms)even with low Bandwidth Consumption (20%).Anybody knows the problem origin ? TKS
Also please remember, that concord (and other tools) measures bandwidth utilization that is average over time (like 5 minutes). But router/switch ALWAYS sends packets at maximum speed. I.E. The link can have two states: Either 0% utilized, or 100% utilized, but over time the results average out. If latency test is done in a time of high peak (e.g. 20 seconds in those 5 minutes the link is almost constantly loaded to 100%) then your queues and tx-rings will fill and you will have latency peak at that time, since latency is measured at certain instances.
Therefore there can be occasional peaks.
