Basic Structure of the IPv6 protocol network in the data center

The transition phase of the network, that is, the transition from IPv4 to IPv6 protocol. Many important organizations have been deployed. Now we will deploy the v6 network in a data center to see what needs to be paid attention to during network deployment. First, let's take a look at the basic information.

When you start to deploy an IPv6 application in the data center or build an IPv6 data center, the idea of building a data center is not the same as that of other networks. Because the data center ultimately needs to provide IPv6 services in an all-round way, IPv6 is the core goal of the data center, it also needs to be able to provide comprehensive external services for IPv4/IPv6 under the current conditions ｡

Current Basic Application of IPv6 protocol

IPv6 protocol applications in the network are mainly used for FTP, WEB services, VOD, file sharing, and other services. Such services have certain requirements on network bandwidth, there is no high requirement on the server's computing power ｡

From the perspective of more mature row-based application computing, the general applications are multi-tier (N-tier) architecture, such as the common C/S architecture and B/S multi-tier application mode, figure 1 ｡

In the traditional IPv4 network environment, the multi-layer software system is very rich and mature, especially the rapid development of middleware. Currently, a large number of enterprise-level computing systems use middleware to implement a wide range of data center services ｡

For upper-layer applications, IPv6 only replaces the network communication layer and only involves modifications to the underlying protocol stack. However, the large-scale computing system based on IPv6 underlying communication is not truly mature, for example, IPv6 operations supported by various databases have matured in the last two years, and the communication level of enterprise core system software is in the early phase of IPv6 protocol conversion ｡
