Next Generation Network Addressing

In early 2011, the Internet Assigned Numbers Authority allocated the last of its inventory of large block IPv4 addresses, and service providers, large enterprises and universities, cloud providers, e-tailers, and federal agencies will find it increasingly difficult to acquire new IPv4 addresses.

Juniper Networks' Next Generation Network Addressing portfolio provides a comprehensive set of technologies that mitigate IPv4 depletion issues while ensuring IPv4-IPv6 co-existence and a pragmatic, business driven transition to IPv6. These technologies, which include IPv4/IPv6 dual stack, NAT44, NAPT44, NAT-PT, NAT64, 6to4-PMT, 6rd, and DS-Lite, among others, can help network operators of all types improve subscriber and service scale, mitigate IPv4 address depletion and pragmatically transition to IPv6 based on business requirements.

Juniper recommends technologies that extend customers current IPv4 address pool and ensure IPv4 and IPv6 co-existence without imposing forklift upgrades or operational penalties. These include technologies such as NAT 44(4), as well as DS-Lite which uses tunneling in combination with NAT.

The Next Generation Network Addressing portfolio consist of individually licensed software products that run on powerful service cards to guarantee high performance throughput and translation rates, and are easily added to new and existing Juniper M Series Multiservices Edge Routers, T Series Core Routers, and MX3D Series Universal Edge Routers, which reduces risk and ensures investment protection. With our IP expertise, leadership on key Internet Engineering Task Force (IETF) Working Groups and a broad portfolio of solutions, we are uniquely qualified to help you meet your unique technical and business requirements.

• High performance, including throughput and translation setup rate. NGNA 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.
• NGNA 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.
