What are some of the more common network performance metrics that are utilized?
What will be an ideal response?
ANSWER: Some of the more common performance metrics are as follows:
* utilization-This metric refers to the actual throughput used as a percentage of available bandwidth. No network should operate at maximum capacity. Identify patterns of utilization and ensure that available bandwidth accounts for utilization spikes.
* error rate-Bits can be damaged in transit due to EMI or other interference. The calculated percentage of how often this occurs is the error rate.
* packet drops-Packets that are damaged beyond use, arrive after their expiration, or are not allowed through an interface are dropped. Packet drops result in delayed network communications while devices wait for responses or have to resend transmissions. Knowing what's normal for your network will help you identify problems when packet drop rates vary.
* jitter-All packets experience some latency. When successive packets experience varying amounts of latency, resulting in their arriving out of order, the user experience is degraded. This is called jitter, a problem that can be addressed through traffic management techniques.
