Method for user equipment to select network layer protocol, home gateway and Internet network

Abstract

The invention discloses a method for user equipment to select a network layer protocol, a home gateway and an Internet network. The home gateway obtains the IPV4 address and IPV6 address returned by the DNS server and corresponding to the domain name carried in the address query request sent by the user equipment; The home gateway detects whether it is connected to the IPV4 address and the IPV6 address; the home gateway returns an address that can be connected to the home gateway among the IPV4 address and the IPV6 address to the user equipment. The method for the user equipment to select the network layer protocol, the home gateway and the Internet network of the present invention determine whether the IPv4 address and the IPv6 address returned by the DNS of the operator are reachable, so as to determine which network communication protocol to use for the user equipment to communicate. Realize the intelligent selection of the network layer protocol stack to ensure the connectivity of communication, guarantee the user's network experience and the normal reachability of Internet applications.

Description

technical field [0001] The invention relates to the domain name service technical field, in particular to a method for user equipment to select a network layer protocol, a home gateway and an Internet network. Background technique [0002] In recent years, due to the imminent depletion of IPv4 addresses, IPv6 technology has developed rapidly, and more and more applications based on IPv6 technology have been applied. In order to support IPv6, operators have upgraded the core backbone network to IPv6, and gradually began to consider deploying IPv6 in the access network to provide users with IPv6 access services. At that time, the coexistence of IPv6 and IPv4 networks will inevitably occur, resulting in many dual-stack users and dual-stack application services supporting both IPv4 and IPv6 protocols, which will inevitably bring about the following problem: when dual-stack users When accessing a dual-stack application server on the Internet, DNS requests for A and AAAA records ...

Problems solved by technology

At that time, the coexistence of IPv6 and IPv4 networks will inevitably occur, resulting in many dual-stack users and dual-stack application services supporting both IPv4 and IPv6 protocols, which will inevitably bring about the following problem: when dual-stack users When accessing a dual-stack application server on the Internet, DNS requests for A and AAAA records will be sent at the same time. Since the accessed server is also a dual-stack application server, both IPv4 and IPv6 addresses will be returned in DNS

Therefore, dual-stack users cannot access the dual-stack application server on the Internet.
