Analysis on IPv6 router and IPv4 Selection

With the continuous update and upgrade of routing technology, IPv6 router technology and IPv4 selection have become the focus of attention. So I have studied the IPv6 router and IPv4 selection problems, I would like to share it with you here and hope it will be useful to you.

When discussing specific IPv4/v6 integrated networking technologies, we must first clarify the specific principles that should be based on during the integrated networking. These principles are actually the basic requirements of IPv4/v6 integrated networking, it is also an important basis for discussing and analyzing IPv4/v6 integrated networking technology. The principles required for IPv4/v6 integrated networking can be divided into the mandatory principles and the reference principles.

(1) protecting existing investments (end users, ISP, ICP, and telecom operators) to the maximum extent)

When researching IPv4/v6 integrated networking solutions, we need to consider the existing investment of various network operators, this includes equipment investment, market investment, technical reserves, and talent reserves. Only good protection of existing investment networking technologies and their corresponding solutions can be highly practical.

(2) ensure intercommunication between IPv4 routers and IPv6 router hosts

The IPv4 router host and IPv6 router host in the network must be able to communicate with each other, including accessible routes and accessible IP packets. Only on the basis of intercommunication between the two can we talk about intercommunication at the application layer.

(3) ensure the normal application of existing IPv4 applications in the integrated networking environment

Existing IPv4 network applications already support a large number of users. The introduction of IPv6 router technology in the network cannot affect existing services, this impact includes the impact of business performance, network reliability, and network security.

(4) avoid dependency between devices. Update of devices must be independent.

The IPv4/v6 integrated networking technology requires that the dependency and coupling between devices be avoided during device upgrade. The available networking technology can be selected for each part of the network, the selection of these technologies cannot restrict the selection of networking technologies and device updates for other networks.

(5) The integrated networking process is easy for network managers and end users to understand and implement.

The simple and easy implementation of the integrated networking process is an important factor in the success of the networking. The complex networking process not only increases the probability of network failures, but also affects the user's follow-up speed.

(6) improve networking flexibility, support gradual network upgrades, and Users have the right to choose when to transition and how to transition

(7) the network service quality should not be significantly reduced after the integrated networking

Because the performance of the IPv6 router is lower than that of the IPv4 router at the same level, the performance of the dual-Stack Router is not very high. Therefore, after the IPv4/v6 integrated networking, the overall performance of the network may be reduced, however, this decline will not significantly affect the service quality of existing services.

(8) after the integrated networking, the network reliability and stability cannot be weakened.

(9) How to give full play to the technical advantages of IPv6 routers during the integrated networking process

The IPv6 router technology is designed to solve the problem of insufficient IP address space. However, it also adds some other functions, such as network security support. In the research of integrated networking technology, we should consider how to make full use of these technical advantages.

(10) design a comprehensive Networking Solution

On the one hand, we must consider the long-term coexistence of IPv4/v6 and the possibility that all networks will adopt IPv6 routers in the future. Therefore, when researching technology, you must note that the selected technology can support smooth network transition without any new obstacles to future network transition. This mode is full duplex. This is one of the reasons why vswitches have better performance than hubs.
