CASE STUDY network . Carrier-grade NAT is often used for mitigating IPv4 address exhaustion .
A lot of the available solutions for enterprise networks have not been developed to solve this critical problem from the ground up . Along with the lack of inbuilt security and dependability means service providers need to be highly selective in their choice of carrier grade equipment .
Carrier-grade network address translation is the solution to this problem , which translates IPv6 addresses for IPv4 servers and allows ISPs to share one IP address among several subscribers .
Christopher Burrell , Head of Network at Vox , explains that the company needed a permanent solution to facilitate the allocation of IPv4 addresses over a long period of time and to accommodate future IPv6 allocations for its clients .
“ The scarcity of IP version 4 , IPv4 , addresses globally is causing certain Internet service providers and network service providers difficulties in bringing new customers on board ,” he explains .
XON . The added benefits for Vox customers include the ability to handle high-volume traffic without sacrificing speed and performance . The A10 solution also provides necessary denial-of-service attack protection to maintain stable connections to the customer base in the event of an attack . Security and robustness are crucial attributes for a carrier-grade service provider to offer .
NEC XON works specifically with A10 Networks because its CGN solution was built to be secure and robust from the ground up . NEC XON added its technical capabilities on top of the A10 solution ’ s capabilities .
A10 Networks ’ IPv4 preservation with CGN and IPv6 migration technologies are reliable solutions that help organisations and service providers increase subscribers , expand their IoT networks , and ensure connectivity .
A10 Thunder , Carrier Grade Networking , provides high-performance CGNAT with protocol translation that allows service providers and enterprise to extend IPv4 investment while simultaneously transitioning to IPv6 standards .
Paul Willemse , Technical Sales Consultant ,
NEC XON
Paul Willemse , Technical Sales Consultant at NEC XON , explains that with all the roughly 4.2 billion IPv4 addresses already assigned , service providers must assign one IP address to multiple users and use IPv6 addresses for new customers . They must also translate IPv6 addresses into a format that older IPv4 servers can understand to maintain compatibility .
Product selection
After thorough research and testing with various CGN vendors , Vox chose A10 due to its features and costeffectiveness , including local support through NEC
A10 Thunder CGN proactively solves IPv4 address exhaustion to overcome the challenges associated with the rapid increase of IP address demands for Internetconnected devices and BYOD roll-out .
Thunder CGN delivers advanced CGNAT features to help service providers and enterprises extend IPv4 connectivity , transition to IPv6 and reduce TCO , while supporting network and infrastructure transformation to cloud-native , 5G , and edge technologies .
As network addressing and IPv6 transition architectures can vary greatly across and within an organisation , customers need a solution that provides the broadest support for industry standards and meets different IP address and protocol translation requirements simultaneously .
Thunder CGN enhances infrastructure security and availability to ensure applications remain addressable and operate transparently through address translation with multiple mechanisms , such as integrated DDoS protection for NAT pools and application layer gateways . Built on A10 ’ s market-proven Advanced Core Operating System , Thunder CGN delivers advanced functionality across the broadest range of form factors .
Thunder CGN can scale from 10Gbps to 300 Gbps throughput ; 16M concurrent sessions to 512M concurrent sessions ; and 120,000 TCP connections per second to 8M TCP connections per second .
