Carrier Grade NAT
Carrier Grade NAT and IPv6 co-existence and transition technologies can help service providers and enterprises of all types survive, and thrive, the depletion of IPv4 addresses.
With the rapid depletion of available IPv4 address blocks, service providers and large enterprises will find it increasingly difficult to acquire new addresses. And while IPv6, which effectively offers infinite IP address space, is used today, deployments must provide access to the IPv4 Internet. The impact of IPv4 address exhaustion, as well as the best path forward, is highly unique to each business and market.
Juniper recommends that customers consider solutions that extend their current IPv4 address pool and ensure IPv4 and IPv6 co-existence without imposing forklift upgrades or operational penalties. In fact, Juniper offers a wide variety of CGN solutions that help customers pragmatically accomplish this, including NAT 44(4), DS-Lite, NAT64 and NAT 6to4. In addition, Juniper also supports complimentary technologies and configuration options, such as 6rd and IPv4/IPv6 Dual Stack.
With our IP expertise, leadership on key Internet Engineering Task Force (IETF) Working Groups and a broad portfolio of solutions that can help customers avoid IPv4 address exhaustion, we are uniquely qualified to work with customers to help them select the best path forward for their situation.
- High performance, including throughput and translation setup rate. CGN runs on service cards which provide dedicated processing resources without impacting the routers forwarding plane or control plane.
- "Toolbox" approach provides customer choice and deployment flexibility
- Reliability: runs on carrier grade router, rather than appliances.
- Scale, including number of translations per service card and number of service cards per router
- Rich application-level gateway (ALG) support
- Low risk service adoption based on mature, field proven products and protocols
- CGN is offered as a simple software addition to existing Juniper router or firewall, which protects customer investment in existing M Series Multiservice Routers, T Series Core Routers,MX Series 3D Universal Edge Routers and SRX Dynamic Service Gateways
