The Operating System for Bangladesh's Internet Infrastructure.
Replace your ৳50 lakh hardware BRAS with software. A modular platform with 13+ plug-and-play modules — billing, RADIUS, OLT management, CGNAT compliance, traffic graphs, hotspot, compliance logging, CRM, accounting, HR, and inventory — all on commodity hardware at wire-speed.
A KaritKarma ProductThe Problem
Bangladesh's ISP industry is stuck in 2015.
Expensive hardware, fragmented tools, manual operations, and zero local software solutions. Every ISP is reinventing the wheel.
Bangladesh has over 2,500 licensed ISPs serving 40+ million broadband subscribers. Most run on expensive hardware BRAS from ZTE, Huawei, or Nokia — costing ৳50-200 lakh per unit — with separate tools for billing, RADIUS, monitoring, and customer management that never integrate properly.
Hardware BRAS Cost
ZTE, Huawei, Nokia hardware BRAS devices cost a fortune and lock you into vendor ecosystems with expensive support contracts.
Fragmented Operations
Separate tools for billing, RADIUS, monitoring, provisioning, CRM, accounting, HR, and inventory that don't talk to each other. Data silos everywhere.
Manual Provisioning
Every new subscriber requires manual router configuration, IP assignment, and RADIUS setup. Human error is guaranteed.
Local Solutions
No Bangladeshi OSS/BSS exists. ISPs depend on foreign software that doesn't understand bKash, BTRC, or local workflows.
Software-Defined BNG
Replace hardware BRAS with pure software.
The first Bangladeshi software vBNG running on commodity x86 hardware. VPP/DPDK data plane, FRRouting control plane, ISC Kea DHCP, and deterministic CGNAT — all integrated into ISPChamp. ISPChamp is built by KaritKarma Limited, a Dhaka-based enterprise and fintech software company, and supports multi-vendor routing (MikroTik, Cisco, Juniper, Huawei, ZTE) alongside 6 OLT vendors natively.

Router Automation
One API for every router vendor.
The same automation ISP operators love in MikroTik — now available for Cisco, Juniper, Huawei, and ZTE. Configure PPPoE, IPoE, queues, firewall, NAT, and hotspot across any vendor from one dashboard. PPPoE and IPoE coexist seamlessly — run PPPoE on existing MikroTik edge routers while migrating newer deployments to IPoE via the software vBNG. Every operation supports transactional rollback.
Bangladesh ISPs typically run mixed-vendor environments — MikroTik at the edge, Cisco or Huawei at the core, with ZTE OLTs. ISPChamp automates all of them through a unified API, eliminating vendor-specific scripting and manual CLI sessions.

FAQ
Common questions
What is ISPChamp?
ISPChamp is a complete OSS/BSS and Software-Defined BNG platform built for internet service providers. It replaces hardware BRAS devices with a software data plane (VPP/DPDK) while unifying billing, subscriber CRM, RADIUS integration, OLT management, CGNAT compliance, payment processing, and multi-tenant operations into a single platform. Built with Go microservices and Next.js portals, it runs on commodity x86 hardware at wire-speed (100 Gbps).
Can ISPChamp replace my hardware BRAS?
Yes. ISPChamp's software vBNG module uses VPP/DPDK for wire-speed packet processing, FRRouting for BGP/OSPF, and ISC Kea for DHCP. It supports IPoE with DHCP Option 82 from any OLT vendor (ZTE, Huawei, BDCOM, CDATA, VSol). Per-subscriber QoS, CGNAT, and ACLs run entirely in software on standard x86 servers with 100G NICs, eliminating the need for proprietary hardware BRAS.
What OLT vendors does ISPChamp support?
ISPChamp includes native SNMP drivers for 6 OLT vendors: ZTE C300/C600 (22 OIDs), Huawei MA5800 (25 OIDs), BDCOM GP3600 (18 OIDs, dual GPON/EPON), CDATA FD1104/FD1108, VSol V1600G, plus a generic driver using IF-MIB and ENTITY-MIB standards. Each driver handles ONU discovery, signal level monitoring (Rx/Tx power), and firmware tracking.
Does ISPChamp support bKash and Nagad payments?
Yes. ISPChamp has built-in payment providers for bKash (OAuth-based), Nagad (RSA-signed), and SSLCommerz. The payment reconciliation engine runs daily with multi-pass matching (exact → unmatched gateway → unmatched local → amount mismatch), auto-resolution, settlement tracking, and exponential backoff retry for failed transactions.
Is ISPChamp BTRC compliant?
Yes. ISPChamp includes deterministic CGNAT logging with BTRC-format CSV export, hourly gzip rotation, configurable retention (default 365 days), and RFC 5424 syslog forwarding. Every NAT session is traceable via deterministic port allocation — the same subscriber always maps to the same (NAT IP, port block) for forensic traceability.
How does multi-tenancy work?
ISPChamp is built as a multi-tenant SaaS platform. Every database query includes tenant_id scoping. Each ISP tenant gets isolated data, billing configuration, RADIUS policies, and user roles. The Darwan authorization service enforces RBAC with 40+ granular permissions and 6 predefined roles (superadmin, ISP admin, operator, viewer, partner, customer).
What routers does ISPChamp support?
ISPChamp supports multi-vendor router automation: MikroTik RouterOS (50+ actions), Cisco IOS/IOS-XE, Juniper Junos, Huawei VRP, and ZTE ZXROS. Actions include PPPoE server configuration, queue management, firewall rules, NAT, hotspot, IP pool assignment, and address lists. All operations support transactional rollback if any step fails.
How much does ISPChamp cost?
ISPChamp is a multi-tenant SaaS platform with per-subscriber pricing. There are no hardware costs — it runs on standard x86 servers. Pricing scales with the number of active subscribers, starting from small ISPs with a few hundred connections. Contact our sales team for a quote tailored to your subscriber count and feature requirements.
How long does deployment take?
A typical ISPChamp deployment takes 2-4 weeks depending on ISP size and existing infrastructure. This includes tenant provisioning, RADIUS integration, OLT driver configuration, payment gateway setup, subscriber data migration, and staff training. The SaaS model means no on-premise hardware — just point your RADIUS to ISPChamp and configure OLT SNMP access.
What add-on modules are available?
ISPChamp offers 7 add-on modules that can be enabled per tenant: Traffic Graphs (MRTG-style monitoring), Log Server (BTRC compliance logging), Hotspot & Captive Portal, CRM & Lead Management, Accounting & Finance, HR & Payroll, and Inventory & Asset Management. Each module integrates seamlessly with the core platform. ISPs pick only the modules they need.
