Juniper supports DS-Lite

Juniper Networks said it is now providing support for Dual Stack Lite (DS-Lite), one of the technological paths service providers can take to migrate toward support of IPv6.

Most experts are firm that the best option for the transition from IPv4 to IPv6 is to support dual stacks. The problem is that not all service providers have the resources and/or the time to implement dual stack. 

DS-Lite is an alternative. DS-Lite allows service providers to handle IPv4 address exhaustion incrementally while using IPv6 as a transport layer for IPv4 in the access network, Juniper explained. DS-Lite allows service providers to handle IPv4 address exhaustion by supporting the deployment of IPv6, and at the same time keeping only one layer of NAT for their subscribers.

"DS-Lite allows incremental build outs where IPv6 needs to be deployed only in the access networks," said Robert Krohn, vice president and general manager, Router Services, Juniper Networks. "The beauty of DS-Lite is that it couples the deployment of IPv6 with a way to share IPv4 addresses, encouraging the industry to move toward IPv6."

Juniper has supported IPv6 forwarding in silicon since its very first product shipment and has been recognized as a global leader in high-performance, next-generation IPv6 networks since 2001. Juniper's CGNAT solutions offer a pragmatic, business driven approach to IPv6 migration. With its broad networking and software portfolio, Juniper provides a comprehensive toolkit that helps enterprises and service providers manage rapidly depleting IPv4 addresses while simultaneously executing an IPv6 migration strategy.
