/ ARCHITECTURAL OVERVIEW

The Challenge: Automating Billing & Network Bandwidth for 45,000 Users

Internet Service Providers (ISPs) struggle with manual bill collection, late-night customer payment verification, and manual MikroTik router provisioning. Customers who paid at 11:00 PM had to wait until morning for human technicians to re-enable their connection, causing immense frustration and customer churn.

Core Architectural Capabilities

Sub-8 Second Auto-Unblock

Customer pays monthly fee via bKash; webhook hits CareITLab billing daemon, sending disconnect command to MikroTik router to immediately re-authorize connection.

Automated Bandwidth Throttling

Grace period management gracefully drops delinquent users to 128Kbps warning splash page instead of sudden disconnection.

Reseller & POP Bandwidth Allocation

Allows downstream ISP resellers to manage sub-clients within allocated overall bandwidth pipes.

Real-Time SNMP Latency & Link Monitoring

Monitors optical fiber distribution points (OLT/ONT) and alerts NOC team via Telegram if a core backbone link drops.

Long-Term Guardian Custody Guaranteed

CareITLab does not deliver static files and abandon your organization. Every platform we build is backed by direct code-level guardianship, proactive security patching, and ongoing performance tuning under our strict SLA frameworks.
