Embodiment 1

[0035] This embodiment mainly describes in detail the implementation method of intelligent 6LoWPAN border routing, as Figure 4 shown, including:

[0036] Step S401: Use the LAN port to carry the 6LoWPAN radio frequency network, as the 6LoWPAN root node itself, initiate a networking command, and establish a network with the 6LoWPAN terminal node;

[0037] The local LAN port of the border router carries the 6LoWPAN radio frequency network and is responsible for managing the local network (networking, IP allocation, local routing, etc.). The physical and link protocols adopt the standard IEEE802.15.4 protocol, and the network layer adopts the standard IPv6 protocol. The networking process initiated by it is as follows: Figure 5 shown. The networking process is as follows:

[0038] The construction process of the local network starts from the root node or border router (LoWPAN Border Router, LBR). The root node first uses DIO to broadcast information about the graph (path); ...

Embodiment 2

[0047] This embodiment specifically describes step S403 in Embodiment 1, as Figure 6 shown, including:

[0048] Step S601: when the remote server is an IPv4 server, execute step S603; when the remote server is an IPv6 server, execute step S602;

[0049] Step S602: determine whether the Internet protocol carried by the local WAN port connected to the remote IPv6 server is an IPv4 protocol, if yes, execute step S605, if not, execute step S606;

[0050] Step S603: determine whether the Internet protocol carried by the local WAN port connected to the remote IPv4 server is an IPv4 protocol, if yes, execute step S604, if not, execute step S606;

[0051] Step S604: start the NAT64 conversion of IPv4 and IPv6 protocols, and go to step S607;

[0052] NAT64 is a stateful network address and protocol conversion technology, which generally only supports access to network resources on the IPv4 side through connections initiated by users on the IPv6 network side. However, NAT64 also sup...

Embodiment 3

[0060] This embodiment mainly describes the process of the remote server accessing the local 6LoWPAN terminal node in step S404 in the first embodiment, which is the reverse process of the local 6LoWPAN terminal node accessing the remote server in the second embodiment, as Figure 7 shown, including:

[0061] Step S701: when the remote server is an IPv4 server, execute step S702, and when the remote server is an IPv6 server, execute step S703;

[0062] Step S702: Determine whether the Internet protocol carried by the local WAN port connected to the IPv4 server is an IPv4 protocol, if yes, perform step S704, and if not, perform step S706;

[0063] Step S703: Determine whether the Internet protocol carried by the local WAN port connected to the IPv6 server is an IPv4 protocol, if yes, perform step S708, and if not, perform step S710;

[0064] Step S704: Encapsulate the IP packet into an IPv4 packet at the remote server, and send it to the border router, and execute step S705; ...

Abstract

The invention discloses an intelligent 6LoWPAN boundary route implementation method and a boundary router. The method comprises the following steps: A, enabling an LAN port to bear a 6LoWPAN radio frequency network and to initiate a networking command, and carrying out the networking with a 6LoWPAN terminal node; B, operating an Internet protocol, corresponding to type of a public network, at a WAN port according to the type of the public network access to the WAN port; C, carrying out the corresponding protocol conversion or packaging processing of an IP message according to the type of the public network access to the WAN port during the forwarding of the IP message transmitted by the 6LoWPAN terminal node to a remote server, and transmitting the IP message after processing to the remote server. According to the invention, the method combines with a WAN port IPv4/IPv6 dual stack and an IPv6 transition module for design, is large in address space, and can meet the demands of the deployment of a large number of terminal devices.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor communication, in particular to a method for implementing intelligent 6LoWPAN border routing and a border router. Background technique [0002] At present, the field of sensor network is mainly ZigBee network. ZigBee currently customizes the protocol standard. The nodes in the ZigBee network complete the Internet access through the application layer design of the ZigBee gateway, and then the ZigBee gateway sends the access results to the nodes. [0003] With the rise of the Internet of Things, whether it is industry or our living environment, we need to connect our equipment to the Internet, and people in different places sometimes need to know some information about the equipment, how to connect our equipment to the Internet, This is what border routing does. [0004] Because ZigBee cannot really achieve end-to-end access between local endpoints and the Internet, that is to say, ...
