What are the benefits of IPv6 routers? IPv6 refers to the 6th version of the Internet protocol, which is the next generation IP protocol to replace IPv4. Its IP number is graphically expressed as: Every grain of sand on the earth can be assigned an IPv6 address. The question then arises, what are the advantages of routers that support IPv6 functionality after enabling IPv6 functionality? This article will take you through the following aspects in detail.
1. High efficiency
When enabled, the NAT function of the router is no longer required, and there will be no IP address conflicts within the LAN, making the router work more efficiently. In addition, the corresponding message header contains only 8 fields, which greatly simplifies the format and enables rapid forwarding of the corresponding message, achieving the goal of improving the corresponding throughput;
2. Faster response time
IPv6 can greatly reduce network latency, making it possible for remote unmanned aerial vehicles, unmanned vehicles, and other scenarios that require high real-time communication requirements. On the other hand, IPv6 routers use smaller routing tables, in which a router can represent a subnet with a single record, improving the speed at which the router forwards packets, reducing network latency from the current popular 100 ms to a single digit;
3. Improved service quality
IPv6 can expand the address space, improve the overall throughput of the network, and support plug and play. In addition, the broadcast function in IPv6 routers is accomplished through multicast, and enhanced multicast support and flow control are very beneficial to improving the quality of service;
4. Higher security
IPv6 standard encryption option allows users to encrypt data on the network layer and verify IP messages, making the communication between users and servers difficult to crack.
5. Good expandability
Supports multiple service types and enables continuous evolution of protocols. The addition of some updated features also allows it to well face the challenges posed by future technological developments;
6. Large expansion of address capacity
Compared to IPv4’s 32-bit address, IPv6’s address bit is expanded to 128 bits, which completely solves the problem of insufficient IPv4 addresses. It also supports a hierarchical address structure, making addressing easier to implement. It can also expand support for multicast and arbitrary broadcast addresses, allowing data packets to be sent to any one or a group of nodes.
Of course, the benefits of IPv6 routers go far beyond these. The above only lists the more prominent advantages. In practical applications, although the computer operating system will give priority to using IPv6 addresses to access the Internet, some applications of IPv6 are still being tested, and the application range is not as wide as IPv4. Moreover, IPv6 is not available on all routers, and it must be supported by network management and optical modem.
