汉英对照:
Chinese-English Translation:

IPv6转换服务(IPv6 Translation Service)是一种有状态的IPv6和IPv4网络地址与协议转换服务。通过IPv6转换服务,具备公网IPv4地址的服务器可快速面向IPv6网络侧用户提供访问服务。

IPv6 translation service is a stateful IPv6 and IPv4 network address and protocol translation service. Through IPv6 conversion service, servers with public IPv4 address can quickly provide access services for IPv6 network side users.

IPv6 转换服务(IPv6 Translation Service),是一种有状态的 IPv6 和 IPv4 网络地址与协议转换服务。通过 IPv6 转换服务,具备公网 IPv4 地址的服务器可快速面向 IPv6 网络侧用户提供访问服务。

IPv6 translation service is a stateful IPv6 and IPv4 network address and protocol translation service. Through IPv6 conversion service, servers with public IPv4 address can quickly provide access services for IPv6 network side users.

IPv6 转换服务当前提供四层模式(支持 TCP 和 UDP 协议)。

IPv6 conversion service currently provides four layer mode (supports TCP and UDP protocol).

IPv6 转换服务的主要功能

Main functions of IPv6 conversion service

IPv6 转换服务最主要的功能是完成 IPv6 和 IPv4 网络地址转换的功能,即完成了 NAT64 的功能。

The main function of IPv6 conversion service is to complete IPv6 and IPv4 network address conversion, that is, to complete the function of nat64.

IPv6 客户端通过 IPv6 网络将数据包发送到 IPv6 转换服务的实例 IPv6 地址上,IPv6 转换服务将数据包的目标 IP 和源 IP 分别完成转换后,数据包将由 IPv6 转换实例的实例 IPv4 地址通过 IPv4 公网转发至用户侧具有 IPv4 公网地址的服务器上。

IPv6 client sends data package to IPv6 address of IPv6 conversion service instance through IPv6 network. After IPv6 conversion service completes the conversion of target IP and source IP of data package, the data package will be forwarded by IPv4 address of IPv6 conversion instance through IPv4 public network to server with IPv4 public network address on user side.

由于 IPv6 转换服务与用户侧的 IPv4 服务器之间的通信是走的 IPv4 公网,因此,原有的 IPv4 业务不论是在 IDC 机房,阿里云上,或者其他公有云上,只要服务器具备公网 IPv4 地址,都可以使用 IPv6 转换服务快速对 IPv6 用户提供支持。

Because the communication between the IPv6 conversion service and the IPv4 server on the user side is on the IPv4 public network, the original IPv4 service can use IPv6 conversion service to quickly support IPv6 users, no matter in IDC room, Alibaba cloud, or other public cloud, as long as the server has a public network IPv4 address.

优势

advantage

IPv6 转换服务有以下优势:

IPv6 conversion service has the following advantages:

高可用,IPv6 转换服务集群跨可用区部署,故障时秒级切换。

High availability, IPv6 conversion service cluster is deployed across availability zones, and switches in seconds when failure occurs.

可配置的网络能力,支持随时调整实例带宽峰值和条目带宽峰值,带宽的修改即时生效。

The configurable network capability supports adjusting the instance bandwidth peak and entry bandwidth peak at any time, and the bandwidth modification takes effect immediately.

极简配置,购买实例,添加映射规则后即可实现 IPv6 和 IPv4 地址和协议转换功能。修改规则实时生效。

The IPv6 and IPv4 address and protocol conversion functions can be realized after simple configuration, instance purchase and adding mapping rules. The modification rules take effect in real time.

适用性强,需要提供 IPv6 服务的 IPv4 服务器不论是在本地数据中心还是在公共云上,只要有公网 IPv4 地址,都可以使用 IPv6 转换服务。

The IPv4 server that needs to provide IPv6 service can use IPv6 conversion service no matter in the local data center or in the public cloud, as long as there is a public network IPv4 address.
