BNG/BRAS solution description

NOVIFLOW-ORDNANCE CLOUD-BASED BNG/BRAS-as-a-SERVICE SOLUTION

NoviFlow’s NoviSwitches combined with Ordnance’s Broadband Aggregation Software offer Network Operators, Cloud Providers and Enterprises Unprecedented Price/Performance in Truly Scalable, Carrier-Grade BNG/BRAS Solution

NoviFlow and Ordnance have joined forces to deliver a BNG/Broadband Remote Access Server (BRAS) solution; the first in a family of performance and cost-optimized Virtual Carrier Services uniting NoviFlow’s high performance forwarding planes with Ordnance’s next-generation telecommunications software platform.

 

WHAT THE BNG/BRAS SOLUTION DOES
  • Combines the separation of control and data planes of Software Defined Networks (SDN) with the resource optimization of Network Functions Virtualization (NFV), turning BNG/BRAS functionality into an on-demand service instantly accessible to customers via an online web portal or API.
  • Provides carriers with the ability to offer end users self-provisioned products and services, slashing service delivery costs, management complexity, and the time it takes to deliver new products and services to market.
  • Delivers Traffic Management and Hierarchical Quality-of-Service (H-QoS) by leveraging NoviFlow’s FlowShaper network processor-based H-QoS and traffic management technology the same network processors already deployed around the world in chassis-based edge routers costing up to 10x more. (See news release NoviFlow Releases FlowShaper.)
BNG/BRAS SOLUTION COMPONENTS

The BNG/BRAS solution comprises two major elements:

  1. The control plane which includes the SDN controller, BNG/BRAS application and required protocol stacks, and
  2. One or more NoviFlow NoviSwitch programmable pipeline edge switches.

1) NoviFlow NoviSwitch OpenFlow Edge Switches

  • Programmable Packet Pipeline implemented on Powerful Multi-Core NPU Silicon
  • Huge QinQ Mapping Tables (Million+ virtual circuits)
  • QoS and Traffic Shaping per User Circuit (requires NoviWare 400.2 and above)
  • Metering per User Circuit
  • Routing of Control traffic (via QinQ tags)
  • Cybersecurity mitigation can be added to Pipeline

2) Ordnance BNG/BRAS Control Plane Software

  • Separation of control plane from forwarding plane for flexible scaling on either plane
  • X86-based VNF Architecture (recommended OS: Ubuntu Linux)
  • IPoE and PPPoE termination*
  • Per subscriber/product ACL’s/Firewall
  • Per subscriber/product HQoS shaping (requires NoviWare 400.2 and above)
  • Per subscriber/product HQoS policing (requires NoviWare 400.2 and above)
  • Product/Service based QoS
  • 1ad S-TAG/C-TAG Service Delivery
  • RESTFul API service provisioning
  • RESTFul API accounting & monitoring
  • MAC Address Authentication
  • DHCP Option 82 Authentication
  • PPPoE Username & Password Authentication
  • Distributed AAA database minimizes reconnect times caused by mass-disconnects

Options

  • Cloud Hosted or On-Premise Controller
  • RADIUS AAA option
  • Wholesale Tennancies
  • DPI/Cyber Security at the Edge
BNG/BRAS SOLUTION ARCHITECTURE

TYPICAL USE CASES
  • Policy Enforcement (QOS), Metering, shaping, scheduling
  • Access tunnelling (PPPoE, L2TP, QinQ, VxLAN, etc)
  • Session management forwarding between VNF and access
  • Access Control and Embedded Security
  • Session load balancing
  • Session statistic
  • IP core tunnelling (L2TP, QinQ, VxLAN, MPLS, PBB, etc)
  • Session forwarding from IP core to access
  • Session forwarding from access to IP core
  • IP routing protocols between VNF (route engine) and IP core
PORT CONFIGURATIONS

NoviFlow’s line of high-performance fully programmable NoviSwitch forwarding planes leverage the advanced packet handling capabilities of the NoviWare Network Operating Software running on high-performance network processors to significantly boost throughput. NoviSwitch is available in a variety of port configurations, with enhanced filtering options at line rates of 1Gbps, 10Gbps, 25Gbps, 40Gbps and 100Gbps, and support up to 16 million simultaneous flows, depending on the NoviSwitch model. As an added benefit, the NoviSwitch/NoviWare programmable match-action pipeline architecture is specifically designed to simultaneously support in a single device multiple network services such as switching, routing, service chaining, firewalling, load balancing, etc.
