Abstract

The invention discloses a load balancing system for an IPv4 terminal and IPv6 service interworking business based on an NAT64 prefix. The system comprises an NAT64 traffic load balancing system and a DNS64 server, wherein a load balancing module and an NAT64 module are arranged in the NAT64 traffic load balancing system connected with an IPv4 network and an IPv6 network respectively; and the IPv6 network accesses a web server via a domain name, and is also connected with the DNS64 server. According to the system provided by the invention, the problem that the service is slow when the load of NAT64 equipment is excessive can be overcome, and load balancing can be performed on an IPv6 data packet with the NAT64 IPv6 prefix matched and configured with a target address.

Description

technical field [0001] The invention relates to the technical field of load balancing, in particular to a load balancing system for IPv4 terminals and IPv6 service interworking services based on NAT64 prefixes. Background technique [0002] In recent years, the Internet is in the transition period from IPv4 to IPv6. At present, most of the content on the Internet is only available on IPv4. Therefore, there is a real demand for IPv6 terminals to access IPv4 resources. Stateful NAT64+DNS64 technology can provide IPv6 end users with the ability to access IPv4 content without changing the user terminal and server. It is currently an important IPv4 / IPv6 dual-stack interworking technology. [0003] Generally, a single NAT64 device can meet the functional requirements of the above-mentioned business applications. However, in the deployment scenarios of operators and large business loads, there are many user connection requests and a large amount of data transmission, and a single N...
