Problems solved by technology

Due to IPv6 network deployment problems or IPv6 application server deployment problems, for example, imperfect IPv6 network deployment or weak processing capabilities of IPv6 application servers, dual-stack terminals cannot establish IPv6 connections with applications, and dual-stack terminals fail to connect to IPv6 In this case, the IPv4 address in the list will be used to establish a connection with the application, resulting in a long delay in the final establishment of the connection between the dual-stack terminal and the application, which will affect the experience of the user when accessing the application.

Abstract

The invention discloses a dual-stack application access method and device, relating to the communication field. This method obtains the IPv6 address and the IPv4 address of the dual-stack application from the DNS server, alternately uses the IPv6 address and the IPv4 address to establish a connection, if any connection attempt is successful, the connection attempt is terminated, and the successful connection is used for communication, which is preferred over IPv6 Access mode, when the IPv6 network deployment is not perfect or the processing capability of the IPv6 application server is weak, it can reduce the connection establishment delay and improve user experience. Moreover, in the process of establishing a connection by alternately using an IPv6 address and an IPv4 address, the IPv6 address can be used preferentially to establish a connection, so as to facilitate the migration of application traffic to the IPv6 network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a dual-stack application access method and device. Background technique [0002] Currently, in the process of dual-stack terminals accessing applications, for example, in the process of dual-stack browsers accessing WEB applications, the general DNS (Domain Name System, domain name system) server will return a list containing A records and AAAA records to the dual-stack At the end of the stack, the A record is the DNS record used to resolve the domain name to an IPv4 address, and the AAAA record is the DNS record used to resolve the domain name to an IPv6 address. The dual-stack terminal generally adopts the IPv6 priority access mode, and uses the IPv6 address in the list to establish a connection with the application. If the connection fails, it will perform three retries. Due to IPv6 network deployment problems or IPv6 application server deployment problems, for example, impe...
