Method for host obtaining network allocation parameterns in IPV6 network

A technology of network configuration parameters and ipv6 network, which is applied in the field of obtaining network configuration parameters by hosts, can solve the problems of individuals using the Internet network, users cannot access the Internet, and does not solve the problems of host acquisition, etc., so as to reduce the process of obtaining network configuration parameters and save hardware and software devices, effect of reducing implementation complexity

Problems solved by technology

[0011] Yet in this scheme, do not solve the problem that host computer obtains corresponding network configuration parameters such as DNS, WINS, at this moment, the user can't visit Internet (Internet) actually, and this has just brought very big trouble to individual using Internet network
For this reason, in RFC3736, the DNS acquisition of stateless address assignment is supplemented, but the option of DHCPv6 (Dynamic Host Configuration Protocol based on IPv6) is still used, and the related DNS and other network configuration parameters are completed through the DHCPv6 protocol. This is contrary to the original design intention of avoiding the use of a DHCP server in a small network, and it also requires the small network to support both ND (Neighbor Discovery) and DHCPv6 protocols, which increases the complexity of implementing a small network
[0012] In summary, it can be seen that none of the current methods for obtaining network configuration parameters in an IPv6 network can solve the problem of obtaining network configuration parameters in an IPv6 network

Embodiment Construction

[0037] The core of the method of the present invention is that after the host that cannot communicate with the DHCPv6 (Dynamic Host Configuration Protocol based on IPv6) server is connected to the IPv6 network, the network end will carry the network configuration parameters that need to be sent to the host end in the expandable field content sent to the host in the protocol packet.

[0038] The method of the present invention is as figure 2 As shown, it mainly includes:

[0039] Step 21: The host accesses the IPv6 network through a router.

[0040] Step 22: Determine that the host cannot communicate with the DHCPv6 server, that is, the network configuration parameter information cannot be obtained through the DHCPv6 server; the inability to communicate with the DHCPv6 server mainly means that some smaller networks do not have a DHCPv6 server, so that the host obtains through the DHCP process Required network configuration parameters.

[0041] Step 23: The router sends the ...

Abstract

After host, which is unable to communicate to server based on dynamic host configuration protocol of IPv6 (DHCPv6), network end sends the parameters of network configuration to the host end. The said parameters are carried by route declaration message or IPv6CP procedure message based on PPP in no state address assignment procedure with expandable content field. Thus, host can obtain parameters of Prefix, DNS and / or WINS needed. Parameters configured for network is accomplished in one-off at IPv6CP phase in PPP dial procedure , or parameters can be obtained through no state address assignment procedure. The invention makes host not supporting DHCPv6 protocol possible to obtain parameters of network configuration.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for a host in an IPv6 network to acquire network configuration parameters. Background technique [0002] In RFC2472 (RFC, Request for Comments), the use of PPP (Point-to-Point Protocol) under the IPv6 (Sixth Internet Protocol) network is defined, and the Interface-Identifier (interface identifier) ​​related to IPv6CP (IPv6 Control Protocol) is defined in the standard ) and IPv6-Compression-Protocol (IPv6 Compression Protocol), but do not define attributes including address Prefix (prefix), DNS (Domain Name System) and WINS (Windows Internet Name Service). Therefore, after PPP dial-up, it is necessary to obtain network access parameters such as address Prefix, DNS, and WINS. [0003] At present, the more common way to obtain address Prefix, DNS, WINS and other parameters is: in the case of IPv6, the host first obtains Interface-Identifier through PPP IPv6CP...
