Asteraix Distributed Broadband Network Gateway Solution
BNG | Small & Medium ISPs
Asteraix’s Turnkey Distributed BNG Solution powered by AsterNOS-VPP(Open Router OS Powered by SONiC & VPP) is specifically designed for small and medium Internet Service Providers (ISPs) seeking a cost-effective, scalable alternative to traditional Broadband Network Gateway (BNG) infrastructure. Asteraix delivers a truly integrated, ready-to-deploy package optimized for operators serving 500-3,000 subscribers per location.
Traditional BNG Architecture
- BNG authenticates subscribers, manages their IP sessions, enforces QoS policies, and routes traffic between their connections and the core network.
- OLT at the head end connects to a single feeder fiber.
- Fiber runs to a passive optical splitter (non-powered).
- ODN relays the signal to multiple ONUs.
- ONU provides connectivity to end subscribers (home/business).
Asteraix BNG Architecture Overview
Access Arch. Comparison:
Traditional BNG vs. BNG powered by AsterNOS-VPP
- Cost-effective DPU+Switch architecture in 1RU pizza box, lower power consumption, and compact server rack implementation.
- Powered by SONiC and VPP, a combination of best practice open-source NOS with high-performance access control, NATTING and HQoS.
- Unified deployment and operation by Controller from cloud or on-premise, optimized for Wi-Fi access.
- XGSPON OLT Stick support as well as 100G Ethernet, suitable for small-to-medium scale access scenarios.
Standalone AAA/BSS/MGMT vs. Controller-Integrated
- Rapid Service Provisioning & ZTP deployment by centrally managing OLT stick, AP, switch, router, and BNG with configuration automatically generated and pushed based on pre-defined network topology.
- Unified, multi-dimensional monitoring view with real-time visibility into network-wide traffic, device health, and downstream subscriber or terminal status.
- Advanced operations with an integrated alarm system and webhook support, allowing external notification through platforms such as WeChat and Slack for events including power, fan, and interface link failures.
- Built-in AAA, DHCP server with Multi-Tenant Subscriber Management, supporting role-based IP assignment, OAuth 2.0 portal authentication, and flexible user and administrator control.
