The data center and branch offices typically do not have the same IPv6 transitioning strategy or timeline. During the transitional periods, one possible scenario is that both the branches and data centers are still using an IPv4 network, but their Internet uplink has been updated to use IPv6. The branch and data center start to roll out WAN optimization solutions on the IPv6 WAN link.
ProxySG’s ADN solution can support all combinations of IPv4/IPv6 scenarios. The three parts that make up the ADN are the branch network, server network, and the ADN tunnel. Any of these three can be using IPv4 or IPv6 independent of one another. In this example, we will illustrate the case where the branch office and data centers are IPv4, while the ADN tunnel (WAN link) is IPv6.
