8 BEST Network Bandwidth Monitoring Software In 2023

Review, compare and select the best Network Bandwidth Monitoring Software from the list to prevent any major network collapse in the future:

You will experience a slow network connection, be it Internet or Intranet, and one of the main reasons for network delays is high bandwidth usage. Slow or bottlenecks are created by hardware or software resources on the network. Such congestion results in low bandwidth, which slows down the network or sometimes crashes the entire network, resulting in total disruption or crash.

One of the best prevention tools in such a scenario is network bandwidth monitoring software. In today’s growing world of IoT (Internet of Things) such software will notify performance issues in advance, which will help IT administrators or network administrators to take necessary actions before catastrophic failures occur.

In this publication, we will look at the top companies that offer software for bandwidth monitoring, their technical specifications, comparison details, and prices. We’ll also look at the factors affecting network bandwidth and how to choose the best network bandwidth monitoring software for your network.

Network Bandwidth Monitoring Software Review

An important role of this software is to monitor incoming and outgoing network traffic. It tracks various devices and their performance to find parameters such as bandwidth usage, latency metrics, data packets (uploads and downloads), device availability and downtime, unwanted packets, and more.

This software monitors all programs and hardware resources blocking bandwidth usage. The results are displayed in either metrics or graphs, which makes it easier for IT administrators to troubleshoot network failures and ensure smooth packet flow.

Pro-Tip: There are various bandwidth monitors, paid and free, designed for small and medium-sized businesses and large businesses, but the bare minimum should contain:

  • Auto-discovery of nodes and network metrics.
  • Device inventory and logging.
  • Configurable alerts.
  • Web-based management interface.
  • Centralized dashboard highlighting performance in graphs and metrics.
  • Intrusion detection.
  • Agentless installation.

If you are looking for granular level management and troubleshooting, then look for commands level management of network settings.

Fact Check: The need for continuous monitoring because of the increasing complexity and security of the network is growing enormously. The network bandwidth monitoring software market is projected to grow 9.9% (CAGR) to $2.93 billion by 2023.

As the following study shows, IT networks and systems contribute significantly to data center outages. In such scenarios, network bandwidth monitor software plays an important role in overcoming such failures.

Frequently Asked Questions

Q #1) How can I monitor bandwidth usage on the network?

Answer: You can use free or paid software to monitor your network bandwidth. If you are in the testing or evaluation phase, you can use the free software or can try the 30-day trial of paid software. If you plan to deploy on a LAN or enterprise network, it is better to use a proven paid version of the software.

Q #2) How can I monitor bandwidth usage per device for free?

Answer: You can use free network bandwidth monitoring software to monitor bandwidth usage, but it comes with basic functionality.

Q #3) Can SNMP monitor bandwidth?

Answer: Simple Network Management Protocol (SNMP) is a protocol used to obtain information about devices connected to an IP network. Network bandwidth monitoring software uses SNMP to get details about various devices (supporting SNMP) from the network to showcase information about bandwidth utilization.

Q #4) What is network bandwidth utilization?

Answer: This means the amount of bandwidth consumed on the network. Network bandwidth monitoring software is used to detect devices and other applications that are using high bandwidth. Such usage can slow down the network and disrupt the network.

Q #5) What is bandwidth capacity?

Answer: Network bandwidth is a capacity that indicates the maximum amount of data (packets) that can be transmitted over a wired or wireless network in a given period. It is represented by the number of bits, kilobits, megabits, or gigabits that can be transmitted in 1 second.

Q #6) What is bandwidth? Explain with example.

Answer: It indicates the speed of data transmission to a local network or Internet connection. The higher the bandwidth, the faster the connection and vice versa.

For example, a local gigabit connection (LAN) has a bandwidth of 1 GBPS or 1000 Mbps.

Factors Affecting Network Bandwidth

Following are some of the factors that lead to high bandwidth usage. Therefore, this bandwidth monitoring software that tracks devices and resources is useful so that IT administrators can take timely action to prevent major network collapse.

  • Faulty network device
  • Huge uploads and downloads
  • Latency
  • Streaming videos
  • Packets lost
  • Resource heavy applications
