Virtual CG-NAT

6WIND Virtual CG-NAT (Carrier-Grade Network Address Translation) is a high-performance, software-based solution designed to help service providers and enterprises efficiently extend their IPv4 networks and enable a smooth transition to IPv6. It aggregates millions of concurrent connections, scales bandwidth from 1G to over 400G, and supports deployment on bare metal, virtual machines, or containers in private and public clouds. The solution is ideal for overcoming IPv4 exhaustion, optimizing network resources, and supporting rapid subscriber growth.

Features

• Carrier-Grade NAT: Supports NAT44, NAT64, and DNS64 for large-scale address and protocol translation.
• High Scalability: Handles up to 30 million simultaneous connections per 32GB RAM and 35Gbps per CPU core, scaling to over 400Gbps per instance.
• Flexible Deployment: Runs on standard x86 and ARM servers, supporting bare metal, virtual, and containerized environments.
• Advanced NAT Features: Includes endpoint-independent mapping/filtering, port preservation, hair-pinning, and address pooling.
• Comprehensive Management: CLI, NETCONF/YANG, SNMP, and advanced logging and monitoring capabilities.
• Multitenancy and VRF Support: Enables secure, isolated networking for multiple tenants.

Capabilities

• IPv4/IPv6 Transition: Enables seamless migration and coexistence of IPv4 and IPv6 networks.
• Resource Optimization: Shares small pools of public addresses among many users, maximizing network capacity.
• Dynamic and Deterministic Port Allocation: Supports multiple port allocation modes for flexible resource management.
• High Availability: Designed for carrier-grade reliability and uptime.
• Policy-Based Routing and QoS: Advanced routing, rate limiting, and traffic management features.

Benefits

• Overcome IPv4 Exhaustion: Efficiently extend IPv4 networks and support rapid subscriber/device growth.
• Cost Efficiency: Deploy on commercial off-the-shelf hardware for reduced capital and operational expenses.
• Operational Flexibility: Deploy in any environment—bare metal, virtualized, or cloud-native.
• Enhanced User Experience: Rich NAT features ensure seamless connectivity and service quality.
• Future-Proof Networking: Supports modern network architectures and evolving service requirements.
