Problems solved by technology
However, it is not difficult to see that they are all typical solutions for stand-alone movement, which obviously do not meet the needs of dynamic changes in the entire subnet range.
If the existing mobile IP method is used to establish routes for the hosts in the mobile subnet, it will not only cause a waste of resources because of distributing a large number of location management messages and establishing independent wireless links for each terminal, but also in Some communication occasions with strict safety and electromagnetic compatibility considerations are not allowed
This also has obvious shortcomings in routing efficiency, switching performance, etc.
In addition, the IPv6 technical solution adopted in the existing mobile network has security problems when the care-of address changes, and cannot provide support for route optimization communication

Embodiment Construction
[0028] Figure 1 shows the architecture of a traditional IPv6 router, which is mainly composed of routing algorithms adapted to traditional fixed networks, routing forwarding with static functions, routing tables, and input / output processing parts. In addition, the interface parts of traditional IPv6 routers are mainly various wired networks. Interface.
[0029] Figure 2 shows the architecture of the IPv6 wireless / mobile router. The router mainly consists of a routing forwarding device with mobile IPv6 functions and a routing algorithm device adapting to dynamically changing networks. In addition, it also has IPv6-based dynamic host configuration and IPv6 network security protection. system, as well as routing table portions and input / output processing devices that conventional routers have. And on the basis of the wired interface of the traditional router, various wireless interfaces such as 802.11x of the wireless local area network WLAN can be added to extend to 802.16 and 8...

This invention provides an IPv6 wireless / mobile router and its method suitable for dynamic variance networks, the router is composed of a router, a network route algorithm device, a dynamic host device, network safety protection system and a route list part and an input / output process device owned by traditional routers. The route transmission device has mobile IPV6 function, the route algorithm device suites the dynamic variance network, the route transmission device is related to route optimum communication feed back rotatable test between mobile nodes and their opposite communication ends. By setting up multiple route paths at the transmit / receive end, active and backup state by device.
Description
Technical field [0001] The invention relates to an IPv6 wireless / mobile router applicable to a dynamically changing network and a realization method. Background technique [0002] In today's rapidly developing information society, the network has become an essential tool for quickly transmitting information, expressing ideas and communicating with each other. With the continuous development of science and technology, the scope and space of people's activities and exchanges are expanding day by day. The traditional communication network composed of wired fixed network equipment can no longer fully meet the needs of human society, economy and military. . How to constitute a wireless mobile network has become an important issue that people care about. On the other hand, because the existing IPv4 network has defects such as lack of address space, poor security, poor mobility, and low quality of service, it has become an inevitable trend that the IPv4 network will be replaced b...
