Network access method and network conversion equipment

Abstract

The invention discloses a network access method and network conversion equipment, and aims to provide a universal network access method for a dual-stack terminal and lower processing loads of a network and a server. The network conversion equipment is arranged among networks provided by different network providers, and distributes a default route to a network terminal under management. The method comprises the following steps that: the network conversion equipment receives a network access request message sent by the network terminal according to the default route when the route is unreachable during network access through a destination address to be accessed, wherein the destination address to be accessed is an Ipv6 (Internet Protocol Version 6) address; the network conversion equipment determines an IPv4 (Internet Protocol Version 4) address corresponding to the destination address to be accessed; and the network conversion equipment performs NAT64 conversion on the network access request message, and forwards the network access request message which undergoes the NAT64 conversion to the determined IPv4 address corresponding to the destination address to be accessed.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network access method and a network conversion device. Background technique [0002] With the rapid development of mobile Internet, cloud computing, Internet of Things and other technologies, various new types of smart terminals and Internet of Things terminals continue to emerge, and users' demand for IP addresses is growing exponentially. The global IPv4 (Internet Protocol Version 4, the fourth version of the Internet Protocol) addresses were announced to be exhausted in early 2011. IPv6 (Internet Protocol Version 6, the sixth version of the Internet Protocol), as the basic bearer protocol of the next-generation Internet, has massive address space capacity and unique Its technical advantages have attracted great attention from the industry, and it has developed rapidly in recent years. [0003] The network is currently in the transition stage from IPv4 to IPv6,...

AI Technical Summary

Problems solved by technology

[0031] Although Happyeyeballs can optimize the selection of IPv4 and IPv6 protocol stacks for dual-stack terminals to a certain extent, and shorten the user waiting time when IPv6 routes fail, it also has the following problems: 1. Terminals or browsers need to support the happyeyeballs mechanism. Currently, most terminals or the browser does not yet support

2. Simultaneously initiate IPv4 and IPv6 TCP connection requests for all services, which increases redundant data packet flow and increases the processing load of the network and server
