Next Generation Network Addressing

In early 2011, the Internet Assigned Numbers Authority (IANA) allocated the last of its inventory of large block IPv4 addresses, and service providers, large enterprises, and universities, cloud providers, federal agencies and others will find it increasingly difficult to acquire large IPv4 address blocks.

Juniper Networks' Next Generation Network Addressing portfolio provides a comprehensive set of technologies that mitigate IPv4 address depletion while ensuring IPv4-IPv6 co-existence and a pragmatic, business-driven transition to IPv6. These technologies include IPv4/IPv6 dual stack, DS-Lite and NAT44, among others.

Dual Stack Lite Example Configuration
DS-Lite allows service providers to deploy IPv6 in their networks without impacting customer IPv4 equipment or IPv4 addressing schemes

NAT44(4) Example Configuration
NAT44(4) allows service providers to non-disruptively extend their current
IPv4 address pool

The Next Generation Network Addressing portfolio is available as licensed software for new and existing Juniper MX Series 3D Universal Edge Routers a well as M Series Multiservices Edge Routers, which reduces implementation risks and ensures investment protection. With extensive IP expertise, leadership on key Internet Engineering Task Force (IETF) Working Groups, and a broad portfolio of solutions, Juniper is uniquely qualified to help you meet your unique technical and business requirements.

• Offered as a licensed software that protects investments in new or existing Juniper MX Series 3D Universal Edge Routers, M Series Multiservice Routers and T Series Core Routers.
• Service cards provide very high address translation performance and density, enabling cost effective service scale without impacting routing or forwarding functions.
• One software license supports many technologies, including IPv4/IPv6 dual stack, NAT44, NAT64 and DS-Lite, among others, which provides deployment flexibility and non-disruptive address scheme evolution.
• Low-risk service adoption based on mature, field proven products and protocols deployed on carrier grade router via software update.
• Rich application-level gateway (ALG) support protects traffic and revenue streams by ensuring compatibility with popular applications that cannot be translated.
