Stingray BNG/BRAS

Designed for internet service providers to manage data plans and control how users access the web

About

BNG (Broadband network gateway) or BRAS (Broadband remote access server) is one of the key components of Stingray Service Gateway. It ensures flexible control over user sessions, management of data plans by customer, and introduction of advanced options.

Solution Architecture

Advantages of Stingray BNG over traditional BNG server gateways

The combination of Layer-2 (PPPoE, DHCP) and Layer-3 modes (IPoE)
Implementing traffic termination (PPPoE, Q-in-Q, VLAN)
Multi-user support (one Login is multiple IP)
Dual Stack IPv4/IPv6 support
White list support based on hostname or URL, including *.domain mask
Increasing the speed of local resources or peer-to-peer networks regardless of the speed of the tariff plan

Prioritization Video, Online games, Web traffic
Traffic coloring (VLAN, IP, MPLS) and work with already colored traffic
Mini-Firewall
BGP and OSPF routing support
Proxying requests between BNG and Radius server thru PCRF server
Synchronize multiple BNG operations and provide redundancy

Stingray BNG operating modes

Operating Mode	Description	Option
SSH-managed BNG Layer-3 IPoE	IP and tariff plans preloading. In case of dynamic IP distribution a Radius monitor or complete implementation of Radius is needed
Radius-managed BNG Layer-3 IPoE	Authorization via Radius-server for the subscribers who already have an IP	Supporting VLAN/Q-in-Q tags
BNG Layer-2 DHCP Relay agent	Subscriber authorization via MAC-address at Radius-server. A DHCP-server is used for IP distribution	ARP proxy, ARP authorization, supporting VLAN/Q-in-Q tags
BNG Layer-2 DHCP Radius Proxy	Subscriber authorization via MAC-address at Radius-server. Instead of DHCP-server a Radius-server is used. DHCP is replaced by combining FastDPI + FastPCRF	Option 82 in the DHCP request, ARP proxy, ARP authorization, supporting VLAN/Q-in-Q tags
BNG Layer-2 PPPoE	PAP, CHAP, MS-CHAPv2, MAC-address authorization protocols are supported	Supporting VLAN/Q-in-Q tags
