What are network performance metrics?


Network performance explains the level of satisfaction that network users derive from using their network. It entails the quality of service a network user receives from the web. Below, we will discuss the various metrics for ascertaining the performance quality of any network.


1. Bandwidth

This is one of the network performance metrics that is measured in Hertz or bit per second. Bandwidth explains the amount of data transmitted through a network in a given amount of time. Hertz categorizes signals transmitted in analog form, while bit per second is used to classify signals transmitted in digital format.

2. Throughput

Throughput refers to the particular amount of deliverable or service produced at the production end and successfully delivered at the receiving end. In-network relates to the amount of data transmitted successfully through a network bandwidth.

Throughput checks the exact number of messages delivered through a network. We can say that a throughput exists within a network bandwidth, so throughput cannot exceed a network bandwidth but can be less than network bandwidth.

3. Latency

Latency in-network is said to be the lag time for message delivery in a network. It explains how long it takes for a message that leaves the sender end to arrive at the receiver end along with a network. If it takes longer for a message to be delivered along with a network, we can say a network has more latency, the lesser time it takes we can say the network has less latency.

4. Jitter

A jitter is a form of latency. It is experienced when a delay variation is caused by the delay of specific data packets sent through a network.

For instance, when we send audio data, video data, and image data through a network, the video and audio data may encounter latency along their transmission path. In this case, the receiving end would experience jitter because the video data is time-sensitive and needs no latency or delay for the successful transmission of data. This is the same with the audio data. But, when downloading a file, jitter is hardly a concern, as the data here is not time-sensitive, and the receiving end can receive the data whenever its download is complete.

5. Packet loss

Packet loss is used to categorize the amount of data packets sent from the sender end that did not arrive at the receiver end. This metric can be measured by identifying the number of data packets that left the sender end and calculating the amount of data that arrived at the receiver end. Now, we can know the number of data packets lost along the transmission process.

6. Bandwidth-delay product

The bandwidth-delay product is a performance metric that helps to capture lost data packets during transmission. It is a performance metric that ascertains buffering needs of a network system. This would help in capturing the lost data packets during the transmission of data along a network path.
