CGNAT

The Internet is running out of unassigned IPv4 addresses, and the industry hopes that IPv6 addresses will solve the problem. However, communications service providers (CSPs) need a solution today to provide services to a growing number of customers.

CGNAT is a solution that implements the functions of network address translation in the network of a telecom operator. The system is aimed to solve the problem of shortage of global IPv4 addresses while maintaining the existing telecom infrastructure. Therefore, many providers are adopting carrier-grade network address translation (CGNAT) to extend IPv4 networks. It thus solves the problem of IPv4 addresses exhaustion, working entirely in a virtual environment without the need for specialized, dedicated hardware.

NFWare vCGNAT is a carrier-grade NAT function that allows transparent IP addresses and protocols by giving one IP address to several clients. vCGNAT is a centralized NAT placed in the service provider's network to help extend the life of an IPv4 network infrastructure and mitigate IPv4 address exhaustion by using address and port translation in large scale. It thus solves the problem of IPv4 addresses exhaustion, working entirely in a virtual environment without the need for specialized, dedicated hardware. It provides the high-quality IP addresses and throughput speed that telcos demand in order to deliver the best customer experience. NFWare is one of the first IP routing technology companies to offer a virtualized CGNAT.
