There's nothing new about IPv6. Network equipment providers and service providers have been preparing to migrate from IPv4 for years. But now that IPv4 address depletion is a reality, enterprises and service providers have to address how they'll migrate themselves and what they can do for their customers. (See LR Live: IPv6 Transition Decisions Loom).
That migration will include supporting both IPv4 and IPv6 traffic simultaneously and, in some cases, using carrier-grade network address translation (NAT) as a migration strategy. As more enterprises move to cloud services, they need to be confident that the services providers they are trusting with their most valuable business have a real plan for their networks.
We've covered several aspects of the move to IPv6 and the concerns involved over the past few months:
Cisco, like other vendors, is looking for validation that it has several of the pieces needed by service providers to proclaim confidently that they have a plan in place for the future of their IP infrastructure. "While the tests performed on the Cisco equipment were done in a lab environment, the results illustrated that performance metrics of commercially available products already support some of the most challenging IPv4/IPv6 interworking scenarios," says Heavy Reading senior analyst Jim Hodges.
Here are the sections for this part of the Cisco Cloud Mega-test, where the emphasis is squarely on showing operators how the network core and data center could scale while moving to IPv6:
