However, when using PPP to carry IPv6, there are some problems, such as: negotiation and configuration of IPv6 network parameters, etc., which need to be solved
[0004] At present, the implementation method of PPP cannot directly negotiate and configure IPv6 network parameters through the IPv6 control protocol (IPv6CP) in the PPP protocol suite, but needs to use additional mechanisms, such as IPv6 stateless address configuration and extended option functions, dynamic host configuration Protocol version 6 (DHCPv6) and extended option functions to negotiate and configure IPv6 network parameters
[0005] In addition to the PPP protocol suite itself, the above-mentioned existing IPv6 network parameter negotiation and configuration methods need to introduce additional mechanisms, thereby increasing equipment implementation and operation overhead and bringing unstable factors
In addition, this is inconsistent with the implementation method in the original IPv4 network, especially in the process of migrating from IPv4 to IPv6, it loses smoothness and continuity. The reason is that in the IPv4 environment, the IPv4 control protocol ( IPCP) various configuration options to directly complete the negotiation configuration of all IPv4 network parameters

Embodiment 1
[0058] Such as Figure 6 As shown, in this embodiment, the PPP configuration option negotiation process includes the following steps:
[0059] Step 101, the host sends a configuration request message.
[0060] Here, the configuration request message is implemented through an IPv6CP message, and the IPv6CP configuration options carried in the IPv6CP message are configuration options such as IPv6 Address, Primary DNS Address, and Secondary DNS Address. At this time, the content of configuration options such as IPv6 Address, Primary DNS Address, and Secondary DNS Address may not contain specific parameter values, and may be empty. After receiving the response from the configuration responder, add specific parameter values.
[0061] Step 102, the reading module of the configuration responder receives the IPv6 message from the host, and reads the content of the IPv6CP configuration option in the IPv6 message.
[0062] Step 103, the processing module of the configuration responder...
Embodiment 2
[0068] Such as Figure 7 As shown, in this embodiment, the PPP configuration option negotiation process includes the following steps:
[0069] Step 201, the home gateway sends a configuration request message.
[0070] Here, the configuration request message is implemented through an IPv6CP message, and the IPv6CP configuration options carried in the IPv6CP message are configuration options such as IPv6-Prefix, Primary DNS Address, and Secondary DNS Address. At this time, the content of configuration options such as IPv6 Address, Primary DNS Address, and Secondary DNS Address may not contain specific parameter values, and may be empty. After receiving the response from the configuration responder, add specific parameter values.
[0071] Step 202, the reading module of the configuration responder receives the IPv6 message from the home gateway, and reads the content of the IPv6CP configuration option in the IPv6 message.
[0072] Step 203, the processing module of the configur...

Abstract
The invention discloses a system for the negotiating configuration of Internet protocol version 6 (IPv6) network parameters. In the system, a negotiating configuration unit is used for the negotiating configuration of the IPv6 network parameters between a requester and a responder based on IPv6 control protocol (CP) configuration options in an IPv6CP message. The invention also discloses a method for the negotiating configuration of the IPv6 network parameters, which comprises the following step of: performing the negotiating configuration on the IPv6 network parameters between the requester and the responder based on the IPv6CP configuration options in the IPv6CP message. By the system and the method, the negotiating configuration of the IPv6 network parameters can be simply realized by directly adopting an IPv6CP in a point-to-point protocol (PPP) family, the overhead of equipment is reduced, and the equipment can be operated more stably and robustly.
Description
technical field [0001] The invention relates to the field of network communication, in particular to a system and method for negotiating and configuring IPv6 network parameters in a point-to-point protocol (PPP, Point-to-Point Protocol). Background technique [0002] As a link layer protocol, PPP has been widely used in various fields such as subscriber digital link (DSL) dialing, authentication, router high-speed link encapsulation, etc. because of its simplicity, high efficiency and good scalability. The network-layer control protocol (NCP, network-layer control protocol) in the PPP enables multiple network-layer protocols, such as IPv4 and IPv6, to be carried simultaneously on the PPP connection. [0003] At the same time, the rapid development of the Internet and the rapid expansion of the scale make the existing IPv4 face many problems in terms of scalability, such as insufficient address space, etc., which need to be solved urgently. Therefore, people developed IPv6 t...
