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.

Assumptions

• Households: 3000

• Plan Rate: 300Mbps

• Device Capacity: 2x 100Gbps Busy-Hour activity: 80%

• Avg.user rate: 80Mbps

Traffic Estimation(Busy Hour)

=3,000 x 80% x 80 Mbps= 192Gbps
Well below 200Gbps
Reliably support 3,000 subscribers

Best-Fit Scenario

Low-density residential regions, like rural and remote areas.
