The rapid growth of the internet has resulted in IPv4 addresses becoming a scare resource, which is increasing the costs to buy or lease IPv4 addresses.
One approach to deal with the finite number of IPv4 addresses is to share the remaining IPv4 addresses among larger numbers of customers. How does this work?
Carrier Grade NAT
Carrier Grade Network Address Translation (CGNAT) enables a single router to act as an agent between the internet and a local private network, so that one public IP address can represent hundreds or even thousands of devices within the private network.
By sharing a public IP address among many private IP addresses, NAT limits the number of public IP addresses a broadband provider has to use, conserving its IPv4 addresses. This enables service providers to sign up new subscribers without having to purchase expensive IPv4 addresses in the open market.
CGNAT Solutions
There are many CGNAT solutions in the market with specialized features and functions, and most of these solutions run on proprietary hardware. However, there is one feature in common among these CGNAT solutions: High Cost.
netElastic Introduces a Virtual CGNAT
netElastic CGNAT is a cost-effective alternative to higher priced solutions. netElastic’s software-based solution can help service providers lower costs by up to 80% compared to traditional CGNAT solutions.
The heart of netElastic CGNAT is a high-performance virtual router, which includes a scalable software architecture that delivers a high-level of translation performance. netElastic CGNAT also has built-in support for application layer gateways to ensure applications are addressable, and operate reliably and transparently through CGNAT.
