Network optimization is a set of best practices used to improve network performance. A variety of tools and techniques can be used to monitor and improve network performance such as: global load balancing, minimize latency, packet loss monitoring and bandwidth management.
With advancements in cloud computing services, applications are now being delivered over the public internet, as well as in private data centers. For enterprises is now even more crucial to deliver secure, high-performance applications ensuring the highest quality of service to their end users. This involves a series of network optimization tools and techniques that can help to identify issues, allowing enterprises to choose the best course of action.
How to measure network performance
There are two ways of measuring network performance – passive and active. Passive measurement tools monitor applications already on the network, gathering performance data metrics.
This gives a realistic representation of real-time conditions, since it focuses on real apps. There is also no danger of network disruption, as there is no additional traffic. Active measurement tools generate data tailored to baseline performance. This does require additional traffic, so must be scheduled at appropriate times.
How to monitor network traffic
Traffic is one of the network optimization considerations when monitoring overall performance. For example, packet loss concerns packets of data that have failed to transmit to their destination. Enterprises can measure traffic on both ends to identify missing packets.
Other metrics for measuring performance include:
Bandwidth – this is the amount of data, measured in bits per second, that can be sent over a given time period.
Jitter – this refers to the variation in time delay for data packets sent over a network.
Latency – this is the amount of time it takes for data to travel from one location to another. This is particularly important as it needs to be as close to zero as possible.
Bandwidth vs. latency
Bandwidth is commonly mistaken for internet speed, but it actually relates to how much data can be received. This is connected to latency because latency also affects network performance, but this concerns delays.
While latency involves the time it takes to initiate communication, bandwidth is how fast the information can be presented to the user.
What affects network performance?
Poor infrastructure, for example old network hardware including routers and cables, can affect bandwidth and latency. Likewise, poor network security may slow down performance as this can drain much-needed bandwidth.
Badly designed applications may consume too much bandwidth, particularly if they are not compatible with the network environment. Lastly, performance limitations on the network, for example, inadequate hardware, can increase packet loss.
Thankfully, there are many solutions to solve these common problems. An application load balancer, for example, can distribute traffic across multiple targets.
