Sandvine Carrier-Grade NAT
In a world where cost cutting is a priority and ESG (Environment, Social and Government) compliance is essential, service providers are looking for ways to reduce the amount of equipment they need while still meeting the needs of their customers.
Managing IP address exhaustion adds complexity to scaling, requiring unnecessary load balancing equipment and complex policy-based routing. This, along with the increasing bandwidth usage and the challenge of migrating from IPv4 to IPv6, is increasing the total cost of ownership (TCO) for service providers.
Sandvine's Carrier-Grade NAT (CGNAT) software module provides a contextually aware, highly scalable, and cost-effective solution for managing IPv4 exhaustion.
CGNAT offers 3 main capabilities:
- Contextual Awareness: This is key in understanding what is on the network to properly manage subscribers throughout their network journey even with a NAT deployment.
- NATSync: This Sandvine feature removes the requirement for IP address load balancing between NAT devices saving CAPEX cost and operational complexities. It synchronizes session states between multiple systems that process NAT traffic and ideal for asymmetric NAT deployments.
- Flexible Logging: This Sandvine feature supports logging options with configurable attributes to fit the service provider's requirements. It includes data format options such as Syslog (TCP/UPD) port block allocation logging and IPFIX flow-based logging.
