Problems solved by technology

[0006] Although the IP address frequency hopping technology can solve the address scanning problem to a certain extent, it also brings new problems, such as the business continuity problem before and after the hopping, that is, the change of the IPv6 address leads to the interruption of online services, affecting the interruption of user service experience

Embodiment 1

[0091] like Figure 5 and Image 6 As shown, the first IPv6 address is a 128-bit address, and the address reservation is successful. The specific process includes:

[0092] Step 60, the first terminal applies for an IPv6 prefix from the BNG device BNG1 through the neighbor discovery ND protocol, and BNG1 sends one or more IPv6 prefixes to the first terminal through the ND protocol, including the prefix Prefix1 and its original lifetime T0;

[0093] Step 61, the first terminal sends an address reservation request to BNG1 before the end of the lifetime T0 of the IPv6 prefix Prefix1, and applies for reserving the first IPv6 address;

[0094] Further, the TCP / UDP connection between the first terminal and the second terminal is using a 128-bit address under Prefix1, that is, the first IPv6 address;

[0095] Further, the address reservation request is carried by a DHCPv6 protocol message;

[0096] Step 62: After receiving the address reservation request, BNG1 judges to agree to ...

Embodiment 2

[0104] like Figure 5 and Figure 7 As shown, the first IPv6 address is a 128-bit address, and the address is successfully reserved again. The specific process includes:

[0105] Steps 70-75 are the same as steps 60-65;

[0106] Step 76, before the extension lifetime T1 of the prefix Prefix1 ends, the TCP / UDP between the first terminal and the second terminal described in step 71 has not been terminated, and the first terminal sends an address reservation request to BNG1 again, applying for reservation of the first IPv6 address;

[0107] Further, the address reservation request is carried by a DHCPv6 protocol message;

[0108] Step 77: After receiving the address reservation request, BNG1 judges to agree to the address reservation request according to at least one of the port to which the first terminal belongs, the logical interface, and the policy configured on the user domain, as well as the authorization information of the first terminal ;

[0109] Step 78, BNG1 send...

Embodiment 5

[0115] like Figure 8 and Figure 9 As shown, the first IPv6 address is a 64-bit address prefix, and the address is reserved successfully. The specific process includes:

[0116] Step 90, the first terminal accesses the router device Router through the point-to-point protocol PPPoE mode based on Ethernet, and completes user authentication, the first terminal applies for an IPv6 prefix to the router device Router through the ND protocol, and the Router sends an or Multiple IPv6 prefixes, including the first IPv6 address and its original lifetime T0, the first IPv6 address is the 64-bit address prefix Prefix1;

[0117] Further, during the user authentication process, the Router receives the authorization information sent by the AAA server, and the authorization information includes the attribute that allows the user address to be reserved;

[0118] Step 91, before the end of the original lifetime T0, the first terminal sends an address reservation request to the Router to app...

Abstract

The invention provides an IPv6 (Internet Protocol version 6) address management method and apparatus, a terminal and a gateway device. The IPv6 address management method comprises: when a first business does not end before the original lifetime of a first IPv6 address ends, a first terminal sends a request to a gateway device for reserving an address reservation request message for the first IPv6 address; the first terminal receives an address reservation response message returned from the gateway device, wherein the address reservation response message at least carries a determination result about whether the gateway device allows the first terminal to reserve the first IPv6 address; and when the determination result, carried in the address reservation response message, indicates that the gateway device allows the first terminal to reserve the first IPv6 address and the address reservation response message carries the continuation lifetime of the first IPv6 address, and the first terminal uses the first IPv6 address and a second terminal to continue to carry out the first business before the continuation lifetime of the first IPv6 address ends. The IPv6 address management method and apparatus, the terminal and the gateway device can realize continuity of user business before and after hopping of IPv6, and can improve the safety and availability for the IPv6 network.

Description

technical field [0001] The present invention relates to the communication field, in particular to an IPv6 address management method, device, terminal and gateway equipment. Background technique [0002] With the rapid popularization of the Internet and the rapid development of data communication technology, the number of global Internet Protocol IP terminals has increased dramatically. The current global Internet Protocol version 4 (Internet Protocol version 4, IPv4) public network address has been exhausted, and the network address translation (Network Address Translation, NAT) technology has many problems in performance and application layer support. The popularization of Internet Protocol version 6 (Internet Protocol version 6, IPv6) technology is an imperative and important issue for global operators and users. [0003] Similar to IPv4 networks, network security is also an important issue for IPv6 networks. By scanning the hosts in the network, you can find information...
