Embodiment approach

[0080] An optional implementation also includes:

[0081] After receiving the DNS response message sent by the DNS server, look up the domain name carried in the DNS response message in the first mapping relationship;

[0082] If the domain name carried in the DNS response message is found in the first mapping relationship, then determine whether to store the corresponding IPv4 address or IPv6 address corresponding to the domain name carried in the DNS response message;

[0083] If it is determined that the IPv4 address or the IPv6 address corresponding to the domain name carried in the DNS response message is not stored correspondingly, then correspondingly store the IPv4 address or IPv6 address corresponding to the domain name carried in the DNS response message in the first mapping relationship.

[0084] The first mapping relationship may be manually collected and set in advance, or may be automatically collected by a dual-stack network device through a DNS response message...

Abstract

The invention discloses a message forwarding method and device, and the method comprises the steps: receiving an IPv6 access request message transmitted by a terminal, and determining whether an IPv6outlet is overloaded or not and whether a target IPv6 address of the IPv6 access request message belongs to a set network segment or not; if it is determined that the outlet of the IPv6 is overloadedor the destination IPv6 address belongs to the set network segment, searching a domain name carried by the IPv6 access request message in a first mapping relationship among the domain name, the IPv4 address and the IPv6 address, and searching a source MC address of the IPv6 access request message in a second mapping relationship among the source MAC address, the IPv4 address and the IPv6 address;if the domain name carried by the IPv6 access request message is found in the first mapping relationship and the source MAC address of the IPv6 access request message is found in the second mapping relationship, regenerating a first IPv4 access request message; and sending the first IPv4 access request message. According to the scheme, overload of an IPv6 exit can be avoided, and the internet surfing experience of a user is guaranteed.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a message forwarding method and device. Background technique [0002] Internet Protocol Version 6 (IPv6) is a next-generation Internet Protocol (IP) designed by The Internet Engineering Task Force (IETF) to replace IPv4. The number of addresses is known as An address can be programmed for every grain of sand in the world. The biggest problem of IPv4 lies in the limited address resources, which seriously restricts the application and development of the Internet, while the use of IPv6 can not only solve the problem of limited address resources, but also solve the obstacles for various access devices to access the Internet, making everything interconnected become possible. [0003] According to the definition of Request For Comments (RFC) 4213, dual-stack refers to the installation of IPv4 protocol stack and IPv6 protocol stack at the same time, and terminals and network de...
