Abstract

The invention relates to a method for configuring an IPv6 address in an operator, which comprises three parts: a client system: the user client can request to configure the current IPv6 address, send a request message and identify a configuration message at any time, and the client can be accessed to a large number of networks provided by operators; the operator host: and the system is responsible for coordinating the communication between the user client and the DHCPv6 server, and can forward and identify the routing message configured by the IPv 6. Storing a mapping table locally to manage and operate the user client; DHCPv6 server: the server is the basis of the whole method, provides all hosts with IPv6 addresses necessary for surfing the Internet, ensures that each client host has a unique IPv6 address and can provide configuration service for all hosts at any time; the three modules are communicated with each other, all information exchange and reading are carried out by the routing message, all links must ensure the smoothness of the information, and the required functions are supported by network equipment or a client system.

Description

IPv6 address configuration method in operator

Technical Field

The invention relates to the technical field of communication, in particular to an IPv6 address configuration method in an operator.

Background

The technology of IPv4 version (Internet protocol version 6) is used in our current Internet protocol, but with the explosive growth of Internet and the use of IPv4 version supporting at most 4,294,967,296 addresses, the current version of technology has not been able to meet the development needs; together with the better performance, security and configuration issues required for network development, it must be implemented using a new IP protocol version IPv 6.

In the IPv4 protocol version, NAT (network address Translation) is used after an operator accesses a large number of hosts. The NAT technology can form a mapping relation between the private address of the local area network and the common address of the operator, so that a large number of hosts can access the network at the same time without applying for a large number of common IP addresses.

In the new IPv6 version protocol, the network address is 128 binary, thereby providing a huge IP address pool. The IPv6 address is divided into two parts: the first 64 bits are network prefixes, which are provided by the network; the last 64 bits are the host address, which is determined based on the link status of the current host.

However, in the existing IPv6 version, when an operator accesses a large number of hosts and the large number of hosts acquire IPv6 addresses, the operator host cannot have a lan management method for the network states of all the hosts, and it is difficult to configure and refine all the IPv6 addresses.

Disclosure of Invention

The invention aims to provide an IPv6 address configuration method in an operator.

In order to solve the above technical problem, the present invention provides a method for configuring an IPv6 address inside an operator, including: after a user host accesses to an operator host and forms a data link, the operator network local area network is connected with a large number of hosts, and the hosts can simultaneously send and receive datagrams from various user clients.

The IPv6 user client can send a routing message to the operating host at any time, and the message carries a request for the client to apply for configuring the local IPv6 address.

And after receiving the IPv6 address configuration request from the client, the operator host immediately forwards the routing message to the DHCPv6 server according to the network link where the operator host is located.

The DHCPv6 server immediately responds to the message after receiving the IPv6 address request sent from the operator host, and sends the generated IPv6 address to the operator server.

And after receiving the address sent by the DHCPv6 server, the operator server forwards the message to the user host and stores the message locally.

The client receives the routing message from the server host, and configures the IPv6 address of the client according to the provided IPv6 address information.

Further, after receiving the routing message from the server, the client system not only configures its IPv6 address, but also sends an acknowledgement message to the server.

The method of the invention can make a large number of hosts simultaneously access to the local area network of the operator, and simultaneously configure the IPv6 address for the host of the lower layer, thus being capable of rapidly completing the identification and the link of the network.

Detailed Description

For the purpose of making the invention, its technical solutions and features more clear, it is described below with reference to the accompanying drawings, which are used as examples or in the prior art, and which are to be construed as being combined in any order.

Fig. 1 is a system structure connection diagram of an IPv6 address configuration method inside an operator, where the method includes four modules.

The module 001 is a local area network part providing the network functions of all modules.

Module 002 is the most important DHCPv6 (Dynamic Host Configuration protocol for IPv6 ) protocol among IPv6 addresses.

Module 003 provides the configuration information for all hosts in the entire lan for the carrier network, managing the network addresses of IPv6 for all hosts in the lan.

Module 004 provides internet access services for the user's personal computer client system.

FIG. 2 provides a flow chart of the principle of information exchange of routing messages between an operator server, a client host and a DHCPv6 server; the system comprises three modules: module 005 is the same as module 004 and module 006 is the operator's server.

Module 007 and module 002 are the same DHCPv6 server providing configuration information for IPv6 addresses for all hosts.

Step s001 is that the user end sends a routing message requesting an IPv6 address to the server of the operator when being linked to the operator network, and requests the operator to configure an IPv6 address for the current host.

Step s002 is that the operator server receives the request from the client host, and then forwards the routing message to the DHCPv6 server of the public network.

Step s003 is that after the DHCPv6 server receives the message from the operator, the identified IPv6 address configuration request configures a complete IPv6 address for the host according to the current routing information, and then directly sends the IPv6 address to the operator server in a unicast manner.

Step s004 is that after receiving the message containing the IPv6 address from the DHCPv6, the operator host reads the configuration information in the message, establishes a mapping table between the host and the IPv6 locally, and sends the message to the client side, where the mapping table corresponds to the IPv6 locally one by one.

Step s005 is configuring the IPv6 address in the local network device immediately after the user client receives the information of IPv6 address configuration, and sending a confirmation message to the operator server.

In summary, the present disclosure provides an IPv6 address configuration method based on the inside of an operator, which is suitable for large-scale users to access a network simultaneously and configure their IPv6 addresses; the situation that the Nat technology cannot be used in the IPv6 network is avoided.

While the foregoing is directed to the preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
