Optimize IP Connectivity Investments

Our IP connectivity solutions include carrier-grade NAT (CGNAT) and IPv6 migration technologies that preserve IPv4 infrastructure, expand IPv4 address capacity and provide a seamless, efficient path to full IPv6.

Sustainable Subscriber Growth is Essential for Business Success

With the exponential growth of subscribers and connected devices, service providers have been investing in infrastructure to support increasing traffic growth while implementing new services to attract new subscribers and increase revenue.

Service providers need definitive ways to address the growing demand for IP connectivity while preserving their existing IPv4 investments. As they prepare to migrate to IPv6, they need to ensure a smooth transition and overcome the compatibility issues with the older IPv4 protocol.

Preserve Existing IPv4 Investments
Organizations that have existing IPv4 infrastructure need to preserve their investments, avoid additional IPv4 investments that could be costly and volatile, and be able to expand services to new subscribers in the future.

Migrate Seamlessly to IPv6

While IPv6 brings forth many advanced capabilities—in addition to a very large address space—it is not backward compatible with IPv4. A successful migration from IPv4 to IPv6 requires careful planning to ensure that all the end-user devices, application servers, and existing network elements continue to operate seamlessly.

Support Subscriber Growth

CGNAT systems and IPv4 transition mechanisms need to maintain high throughput, connections per second, concurrent connection rates, and more, at consistent carrier-grade levels. Sustaining growth will help reduce customer churn and avoid increased customer acquisition costs.
