IPv6 network protocol-compatible networking Benchmark

In the face of the coexistence of the two network protocols, We have to thoroughly consider the transition and compatibility between IPv4 and IPv6 network protocols. The development of IPv6 is not as optimistic as we have predicted. There are many problems. Let's analyze it briefly. First, let's take a look at the basic principles of integrated networking.

With the continuous research on the Transition technology from IPv4 to IPv6, the industry has been deeply aware of the Transition problem. IETF's understanding of this problem has gone through the Migration of Migration and Transition), Integration), Interoperation) long-term Co-existence) stage. In the long run, IPv4 and IPv6 technologies will coexist in the network for a long time ). In the future, IP networks will be integrated between IPv4 and IPv6 networks.

Basic principles of integrated networking

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) protects existing 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 and IPv6 network protocols

IPv4 and IPv6 hosts in the network must be interconnected, 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 that the existing IPv4 application works normally in the integrated networking environment

Existing IPv4 network applications already support a large number of users. The introduction of IPv6 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) increases the networking flexibility and supports gradual network upgrades. 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 decline, but 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.

IPv6 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) when designing a comprehensive networking solution, we must consider the long-term coexistence of IPv4 and v6, and the possibility that all networks will adopt the IPv6 network protocol 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.
