The 5G buzz is building and along with it are projections that some 5G networks will launch in 2018, with more widespread deployment in 2019. The launch of 5G networks will contribute to the large-scale proliferation of Internet of Things (IoT) devices.
The IoT devices will need a new IP address to connect to the internet, but the exhausation of the IPv4 address space looms. IPv6 promises to solve this dilemma. While most of these new devices connected to 5G networks will have IPv6 addresses, network operators must still support two IP addressing schemes for quite some time.
With a mix of IPv6 and v4 devices on both mobile networks and the internet, service providers need a strategy to manage communication effectively across all devices. Much of this translation will happen within the SGi/Gi-LAN in the operator’s environment. The question is, what can operators do to manage that transition?
CGNAT Will Solve Dilemma
Carrier-grade network address translation (CGNAT) is heralded as the answer to this dilemma, but it must be implemented with a strategy to ensure business continuity. Since every service provider network varies in size and complexity, a CGNAT and IPv6 migration solution much be flexible to account for different integration options.
IoT networks and 5G networks will include a myriad of devices — all with different security profiles and capabilities — so the risk of attacks from internally connected devices within a service provider network will continue to rise. Therefore, any CGNAT solution sitting in the SGi/Gi-LAN needs to be sufficiently robust to guard against internal attacks, as well a external threats.
Extend IPv4, Enable IPv6
A new A10 networks white paper provides an overview of the various components required for a complete CGNAT and IPv6 migration solution that encompasses the entire lifecycle of the transition to IPv6.
A proper strategy includes options for flexible deployment and integration, performance, application integrity, visibility and compliance, security and availability. Each of these factors will contribute to a robust set of address and protocol translation techniques to properly address an evolving environment.
The white paper offers an overview of A10 Thunder® CGN — powered by A10’s Advanced Core Operating System (ACOS®) — that enables service providers to mitigate the impact of IPv4 exhaustion while simultaneously easing the transition to IPv6.
A10 Thunder CGN allows service providers to achieve high-performance, highly transparent address and protocol translation that extends IPv4 network connectivity while smoothing the migration to IPv6.
Service providers need to plan for the billions of IoT devices that will likely be flooding networks in the coming years.
