Embodiment Construction

[0037] In the basic PMIPv6 policy file, the main mandatory information includes: MN_ID and LMA address, etc. The optional information includes: the Home Network Prefix (Home Network Prefix, HNP) of the MN, the lifetime of the prefix, and the address configuration mode supported by the PMIPv6 domain. In order to realize the dynamic update of DNS, the present invention adds to the above optional information:

[0038] 1) FQDN of the MN, that is, the name information of the MN;

[0039] 2) The DNS dynamic update method (DNSUPDATE, DU) supported by the PMIPv6 domain, the value of the 2bits parameter is as follows:

[0040] 00: MN's AAAA record and PTR record update are performed by LMA;

[0041] 01: MN's AAAA record is executed by MN, and MN's PTR record is executed by LMA;

[0042] 10: The AAAA record and PTR record update of the MN are performed by the AAA server of the LMA domain;

[0043] 11: The AAAA record of the MN is performed by the MN, and the PTR record of the MN is ...

Abstract

The invention provides a dynamic DNS (domain name system) updating method of a PMIPv6 (proxy mobile IPv6). According to the method, the basic PMIPv6 signalling message and the interactive process are expanded, the function of realizing the DNS information dynamic updating of an MN (mobile node) is supplemented, in addition, the support on various possible requirements of DNS updating operation can be guaranteed through flexible marking positions, finally, the DNS information of the MN can be updated in the PMIPv6 environment, and the compatibility with PMIPv6 protocols is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of network information, and in particular relates to a PMIPv6 dynamic DNS update method. Background technique [0002] DNS (Domain Name System) is often referred to as the domain name system. Every host on the Internet is identified by IP. However, these cumbersome numbers are not only difficult to remember, but also have no meaning. Therefore, there should be an easy-to-remember and meaningful way to identify hosts on the Internet. , that is the domain name, such as NetEase's domain name is http: / / www.163.com / . So how does the domain name correspond to the IP? There are many DNS servers on the Internet, and the corresponding relationship between IP and domain name is recorded in the database of the DNS server. When you want to access a certain host, just provide the domain name of the host, and DNS will help you resolve the IP of the host. DNS is an important basic resource of the Internet, and almost al...
