Exceeding Engineering Limits - What Happens?
Hi, I am trying to put together some documentation explaining what happens when some engineering limits are exceeded for the following metrics. Although I am familiar with a number of these metrics, there are many I am not.
If anyone could assist or point me in the right direction it would be appreciated. Even if you can only offer input to one metric. I would assume that some of these metrics may have hard limits and can not be exceeded, unfortunately I am not in a position to test.
CPU Utilisation Eg. Sustained very high CPU can impact performance & control & data plane processes.
Memory Utilisation Eg. High memory utilisation can impact performance & control & data plane processes.
Throughput (PPS) Eg. Packet loss, which can lead to re-transmissions and additional traffic.
Backplane utilization Eg. Packet loss, which can lead to re-transmissions and additional traffic.
