Network Address Translation (NAT)

  • »
Network Address Translation (NAT) - the network address translation system, which makes it possible to use one public address for multiple devices with local addresses. Service providers deploy NAT in such a way that multiple subscribers can share a single global IP address.

The positive properties of NAT:

  1. Ease of implementation for the telecom operator
  2. Ability to manage the network

The network address translation in the CGNAT solution enables telecom operators to extend the use of the limited IPv4 address space, to handle a large number of concurrent connections, and to simplify the migration to IPv6 addressing.

The advantages of address translation:

  • Decreased the use of public addresses
  • Increased flexibility of using addresses
  • Increased security

Mechanisms for scaling and improving the performance of IP networks of providers:

  • NAT44 will improve the efficiency of IPv4 address translation
  • NAT64 mechanism that allows access to content from IPv6 networks in IPv4

NFWare 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. NFWare is one of the first IP routing technology companies to offer a virtualized CG-NAT and it is optimized to run on standard x86 servers and in hypervisor.
