Overview

The Bandwidth Estimator helps calculate fair internet bandwidth allocation across multiple client groups, offices, departments, hotspots, VLANs, or customer segments using weighted bandwidth distribution. It estimates usable download and upload capacity after reserved bandwidth and calculates how much bandwidth each group and individual user may receive based on configured priority weights.

Common Use Cases

How to Use

1
Enter the total available download bandwidth from your internet connection.
2
Enter the total upload bandwidth capacity.
3
Set a reserve percentage to keep part of the bandwidth unused for stability and burst protection.
4
Add client groups such as offices, departments, VLANs, hotspot groups, or customer segments.
5
Specify the number of users in each client group.
6
Set download and upload weight values to prioritize certain groups over others.
7
Review the calculated allocated bandwidth and estimated per-user speeds for each group.

Example Scenario

Office and Guest WiFi Sharing

A company has a 300 Mbps download and 100 Mbps upload internet connection with 10% reserved bandwidth. The office network is given higher priority than guest WiFi using weighted allocation, allowing business-critical users to receive more stable bandwidth during peak usage.

Technical Notes

Bandwidth is distributed proportionally based on configured download and upload weights rather than equally between all client groups.

Reserved bandwidth reduces the usable internet capacity to maintain network stability, avoid full saturation, and improve latency during traffic spikes.

Per-user bandwidth is estimated by dividing allocated group bandwidth by the number of users within that group.

Download and upload allocation are calculated independently, allowing different prioritization for upload-heavy or download-heavy workloads.

The estimator models fair bandwidth sharing and planning scenarios but does not enforce traffic shaping or queue management directly.

Common Mistakes

Frequently Asked Questions

Reserve bandwidth keeps part of the internet capacity unused to improve network stability, reduce congestion, and maintain lower latency during peak traffic.

Weighted allocation distributes bandwidth proportionally based on configured priority values instead of splitting bandwidth equally between all groups.

No. This tool estimates bandwidth distribution and planning values but does not generate router configuration directly.

Per-user bandwidth is calculated by dividing the allocated group bandwidth by the total number of users in that group.

Yes. Some environments such as video conferencing, cloud backup, or streaming may require different upload and download priorities.
