CG-NAT: Fortinet &




Recent years have seen a tremendous and accelerating increase in demand for data networking capacity from carriers and enterprises. The multiplication of mobile and connected devices, the proliferation of streaming video-based applications, and cloud-based services will only augment the challenge of delivering capacity and ensuring quality as data moves from web to mobile to machines. To compound the issue, the surge in IoT and the recent global depletion of public IPv4 addresses strains existing IPv4 infrastructures and increases demand for CG-NAT IPv4 services.


NoviFlow’s CGNMapper and Fortinet’s CG-NAT service: Terabit capacity and dynamic scaling to stay ahead of today’s exponentially growing demand for CG-NAT services

The joint solution combines NoviFlow’s NoviMapper SDN-enhanced forwarding plane with Fortinet’s FortiGate CG-NAT service, effectively incorporating this service in the SDN network. Together, the NoviFlow/Fortinet solution delivers high throughput and dynamically scalable CG-NAT services in a programmable SDN networking environment that can handle complex flow processing, massive throughput, scalability, making it possible for Fortinet’s CG-NAT users to stay ahead of today’s exponentially growing demand. The solution delivers cost-effective filtering and load balancing functions and can handle over 1.5T of throughput while reducing total customer network CAPEX and OPEX.

  • Terabit Load Balancing from Private (CPE) side
  • Terabit Traffic Steering from Public (Internet side)
  • Proprietary algorithm that for the life of a Private flow, and its Public Internet response, both are pinned to a specific CGN Tool. This enables the NAT mapping of flows, and the associated database, to be divided and isolated to specific Tools within the Farm
  • Operational Dashboard to Visualize Tool state and loads
  • Enable Scaling capacity of Tool Farm
  • Simplify configuration and management of flows to tools
  • High Availability (HA) support for link, switch, CGN Tool, and CGNMapper Controller
  • API interface for integration with 3rd party Orchestration package if required
  • Cost-effective, dynamically scalable, multiple Terabit CG-NAT services
  • Efficiently address even the largest deployments and enable cost-effective dynamic scaling to right-size capacity for even the most highly variable demand
  • Automation of address handling reduces network complexity and operating costs
  • Works with existing Fortinet CG-NAT tool farms and installations
