ISP Bandwidth Management — Traffic Control

Reviewed by the NowaCRM ISP operations team Last updated: May 18, 2026

Quick answer

Bandwidth is your most valuable resource as an ISP. Over-provision and you waste money. Under-provision and subscribers churn. NowaCRM gives you granular control over bandwidth allocation — per subscriber, per plan, per time of day — using RADIUS-based rate limiting and real-time network monitoring.

01

Per-Subscriber Bandwidth Control

Every subscriber gets exactly the bandwidth their plan allows. NowaCRM assigns download and upload speeds via RADIUS attributes during PPPoE authentication. MikroTik rate-limits, Cisco VSAs, and standard RADIUS bandwidth attributes are all supported. Speed changes happen in real-time via CoA — no session restart required.

02

Real-Time Bandwidth Monitoring

Track bandwidth consumption across your entire network in real-time. Per-subscriber, per-NAS, and aggregate views show you exactly where bandwidth is being used. Identify heavy users, detect anomalies, and spot congestion before subscribers complain. Historical usage graphs help with capacity planning.

03

Plan-Based Speed Profiles

Define speed profiles in your broadband plans — base speed, FUP throttled speed, burst speed, and burst threshold. NowaCRM translates these into the correct RADIUS attributes for your NAS vendor. Upgrade a plan's speed and all subscribers on that plan receive CoA packets updating their bandwidth instantly.

04

Peak Hour Management

Network congestion typically peaks during evening hours. NowaCRM can help you identify peak patterns through bandwidth analytics and usage reports. Combined with FUP management, you can implement policies that ensure fair bandwidth distribution during high-demand periods.

05

Bandwidth Usage Reports

Generate daily, weekly, and monthly bandwidth reports per subscriber, per plan, per partner, or per NAS. Track average usage vs. plan allocation. Identify underutilized plans (opportunity for downsell) and overutilized plans (upsell candidates). Export to Excel or schedule automated email delivery.

FAQ

Frequently Asked Questions

How does NowaCRM control subscriber bandwidth?

NowaCRM assigns bandwidth limits via RADIUS attributes during PPPoE authentication. For MikroTik, it uses the Mikrotik-Rate-Limit attribute. Speed changes are applied instantly via RADIUS CoA.

Can I monitor bandwidth usage in real-time?

Yes. The dashboard shows real-time session data including per-subscriber bandwidth consumption, per-NAS aggregate usage, and historical usage graphs.

Does it support burst speed?

Yes. Plans can define burst speed and burst threshold. These are translated into the appropriate RADIUS attributes for your NAS vendor (e.g., MikroTik burst parameters).

Can I generate bandwidth usage reports?

Yes. Daily, weekly, and monthly reports can be generated per subscriber, plan, partner, or NAS. Reports can be exported to Excel or scheduled for automatic email delivery.
