Scheme of eSurfing Cloud IPv4/IPv6 Dual-Stack

POD calculation: The overlay scheme of IPv6 over IPv4 is adopted, for which the network layer of physical devices does not perceive IPv6 messages and no changes are required.

Network service area: Add the deployment of vrouter6 node, and transfer a IPv6 message in underlay mode after it passes through vrouter6 node.

Internet egress area: IPv6 traffic from and to the Internet is securely protected and transmitted.

Double-stack strategy is applied to realize genuine IPv6 upgrading

Double-stack strategy is to run IPv4 and IPv6 protocol stacks simultaneously in network elements, which is the most thorough technology for websites to support IPv6 upgrading.

It can realize the single protocol stack communication for IPv4-to-IPv4 and IPv6-to-IPv6 with good access effect.

ECS: Provide the ability to access the Internet in dual-stack mode

VPC: IPv6 interworking within VPC, dynamic IPv6 BGP routing within VPC, and VPC PPC supporting IPv6

EIP: Support EIP IPv6 import, Console configuration, and billing by bandwidth/traffic

ELB: Unified ELBs to work with IPv6 (Intranet and Internet)
