Network Performance Monitoring (NPM) is the process of visualizing, monitoring, optimizing, troubleshooting and reporting on the service quality of your network as experienced by the customers.
▶ Factors that impact network performance
• Bandwidth
Bandwidth commonly measured in bits/second is the maximum rate that information can be transferred.
• Throughput
Throughput is the actual rate that information is transferred.
• Latency
Latency is the delay between the sender and the receiver decoding it, this is mainly a function of the signals travel time, and processing time at any nodes the information traverses.
• Jitter
Jitter is a variation in packet delay at the receiver of the information.
• Error rate
Error rate is the number of corrupted bits expressed as a percentage or fraction of the total sent.
• Packet loss
Packet loss refers to the number of packets transmitted from one destination to another that fail to transmit.
