Description
Technical Field
The invention relates to a mesh network, in particular to a method for carrying out IP addressing access on nodes in the mesh network.
Background
The access to the node device through the IP address is still the most common way in the application field of the Internet of Things (IoT), for example, the local access to the node device of the local area network through the mobile phone, and the remote access to the node device through the connection between the mobile phone and the cloud server, and in these scenarios, the access to the node device through the IP address is required. For example, in a common non-IP mesh network (e.g., a mesh network such as bluetooth and ZigBee that does not use an IP address for communication between nodes), a node device often needs to implement the capability of interworking with an external network through a gateway device. However, in such a non-IP mesh network, the external network device cannot directly access the device in the mesh network through the IP address.
The inventor researches an addressing scheme of the existing mesh network, and notices that the scheme of the prior art does not well solve the problem that an external device accesses a node device in the mesh network through an IP address.
For example, chinese patent CN101621449B discloses a method for accessing terminals and a method for updating proxy in a mesh network, in which a network-wide uniform IP address is configured for all terminals in the mesh network, and all terminals have a unique and uniform IP address in the whole mesh network. On one hand, in the scheme, the terminal in the mesh network and the mesh node use the same IP address to access the external network, which is not beneficial to accessing the mesh network equipment from the outside of the mesh network through the IP address. On the other hand, in the scheme, the allocation of the IP address follows the conventional DHCP protocol, the DHCP client initiates a request to the DHCP server, and after a plurality of handshaking interactions between the two parties, the DHCP client can obtain the IP address allocated by the DHCP server.
For another example, chinese patent application CN108092830A discloses a method for applying TCP/IP protocol in Mesh network, wherein common nodes are configured with the same IP address in the whole network, so that they have the same IP configuration as the root node, and wherein addresses are allocated by means of beacon transmission.
For another example, the chinese patent application CN104936168A discloses an efficient wireless mesh networking method, in which mesh network nodes communicate with each other by using IP addresses. The scheme mainly solves the problem that the nodes in the IP mesh network access the external network through the TCP/IP.
In summary, there is a need in the art for a method for IP addressing access to nodes in a mesh network (especially a non-IP mesh network that does not use IP addresses for inter-node communication) to solve the above-mentioned problems in the prior art. It should be understood that the above-listed technical problems are only exemplary and not limiting to the present invention, and the present invention is not limited to the technical solutions for simultaneously solving all the above technical problems. The technical solution of the present invention may be implemented to solve one or more of the above or other technical problems.

Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, exemplary embodiments. It is to be understood that the embodiments shown in the drawings and described below are merely illustrative and not restrictive of the current invention.
Fig. 1 is a schematic flow diagram of a method 100 for IP addressed access to nodes in a mesh network according to one embodiment of the present invention. The mesh network includes a plurality of nodes including a root node and one or more node devices. At step 102, providing a DHCP service at a root node; in step 104, the root node allocates a unique internal IP address to each node device in the mesh network through the DHCP service; in step 106, a root node in the mesh network communicates with an external device through a first protocol; at step 108, the plurality of nodes in the mesh network communicate with each other via a second protocol, wherein the second protocol is different from the first protocol. In a preferred embodiment of the invention, the first protocol is the TCP/IP protocol and the second protocol is the MAC protocol. Since the second protocol is a different protocol than the TCP/IP protocol, the internal communication of the mesh network is not dependent on IP addresses and IP connections. It is to be understood that the practice of the present invention is not so limited and those skilled in the art can select the appropriate first protocol and second protocol depending on the needs of the application.
In this way, the method of the present invention enables seamless connection of the mesh network to the external internet. The method proposed herein does not rely on special configuration of external devices (such as routers) nor does it require special processing capabilities of the external devices.
FIG. 3 is a schematic flow diagram of assigning an address to a newly joined node by a root node according to one embodiment of the present invention. In step 202, each node device to be added to the mesh network sends an add device message containing a second protocol address of the node device to the root node through a second protocol; in step 204, after receiving the message of adding the device, the root node allocates a unique internal IP address to the end device through the DHCP service, and the root node stores the mapping between the second protocol address of the node device and the internal IP address thereof in the internal IP mapping table; at step 206, the root node sends a DHCP pre-allocation message (e.g., a "DHCP Offer" message) with the assigned internal IP address to the node device via the second protocol.
Fig. 3 is a schematic network diagram illustrating a process in which a new node joins a mesh network and is assigned an address by a root node, according to one embodiment of the present invention. As shown in fig. 3, when the leaf node E joins the mesh network, it sends an "add device" message of its MAC address to the root node via a second protocol (e.g., MAC protocol). The message is forwarded in the mesh network through the intermediate node B to the root node. Upon receiving this message, the root node assigns a unique internal IP address 192.168.1.104 to leaf node E via DHCP service, and the root node saves the leaf node's MAC address and its internal IP address 192.168.1.104 to an internal IP mapping table. The root node then sends a DHCP Offer message with the assigned internal IP address to the leaf node E by forwarding it via the intermediate node B via the MAC protocol.
As a non-limiting example, an internal IP mapping table is maintained at the root node mapping the second protocol address of each node device in the mesh network to its internal IP address as shown in the following figure:
| device address | IP address |
| MAC address B (intermediate node B) | 192.168.1.101 |
| MAC address E (leaf node E) | 192.168.1.104 |
| … | … |
In the solution of the invention, only the root node provides the function of the DHCP server, and the IP addresses of all devices in the network are assigned by the root node. Based on the MAC address list of all the devices in the network managed by the root node, after all the devices join the network, the devices send an 'add device' message to the root node so as to enable the root node to add the MAC address of the root node into the MAC address list maintained by the root node, and after receiving the message, the root node allocates an IP address for the devices by a DHCP server and replies the message with the IP address (DHCP offer message) to the newly-added devices. The process avoids the traditional DHCP multi-time handshake process, and only multiplexes the existing new equipment to join the network confirmation packet to complete the process of acquiring the IP address. In addition, a "delete device" message that a device sends to the root node after checking that its child node has left may also be utilized by the root node to identify that the corresponding IP address is unavailable.
For example, in an embodiment of the present invention, when a node device leaves the mesh network, the node device sends a delete device message to the root node through the MAC protocol; and after receiving the message of deleting the equipment, the root node deletes the mapping corresponding to the node equipment in the internal IP mapping table and the external IP mapping table.
In a further preferred embodiment, when a parent node of a node device deletes the node device from the mesh network, the parent node sends a message containing a deletion device corresponding to the node device to the root node through the MAC protocol; and after receiving the message of deleting the equipment, the root node deletes the mapping corresponding to the node equipment in the internal IP mapping table and the external IP mapping table.
It should be understood that although the mesh network topology shown in fig. 3 is a tree structure, the implementation of the present invention is not limited thereto. For example, the inventive arrangements may be applied to any topology having a unique root node.
Fig. 4 is a network diagram according to one embodiment of the invention. Alternatively, the root node may have an external IP address as shown to connect to an external network. By way of non-limiting example, the external network may be the Internet, a wide area network, a local area network, a distributed system, and so forth. In fig. 4, the root node has an external IP address 147.136.23.7 and an internal IP address 192.168.1.1.
In a preferred embodiment, an external IP mapping table is maintained at the root node, wherein the external IP mapping table maps internal IP addresses of node devices in the mesh network to external IP addresses. For example, in an embodiment of the present invention, the root node may be equipped with a NAT (network address translation) function to translate an internal IP address of the mesh network device into an IP address of the public network, and the external device may distinguish the node devices in the mesh network through different connections.
By way of example and not limitation, an example external IP mapping table for a root node is as follows:
| local IP address and port | Public network IP address and port |
| 192.168.1.104:5001 | 147.136.23.7:7005 |
| 192.168.1.104:5003 | 147.136.23.7:7801 |
| 192.168.1.101:3008 | 147.136.23.7:6262 |
As shown in the above figure, the external IP mapping table may map < internal IP address of a node device in the mesh network: internal port > maps to < external IP address: external port >. It should be understood that the implementation of the present invention is not so limited, and the mapping between the internal IP address and the external IP address may or may not include a port.
Fig. 5 is a schematic diagram of an IP connection model of each node in the mesh network according to an embodiment of the present invention. Based on the method of the invention, the mesh interface provides the address of the binding IP to the application layer, so that the application layer does not need to care about the role of the equipment in the mesh network, thereby obviously simplifying the processing of the application layer to the mesh network.
By way of non-limiting example, when one node device in the mesh network sends an IP packet to an external device (not shown) having a first external IP address, e.g., leaf node E attempts to access https:// www.espressif.com/, leaf node E may send an IP packet with a target IP address of the first external IP address to the root node through the MAC; the root node determines 192.168.1.104:5001 internal IP address and port of the node device through an internal IP mapping table, and determines 147.136.23.7:7005 external IP address and port corresponding to the node device through an external IP mapping table; then, the root node transmits the data packet with the target IP address as the first external IP address to the first external device through the TCP/IP protocol.
On the other hand, when the root node receives an IP data packet of which the target IP address exists in the external IP mapping table through a TCP/IP protocol, the internal IP address of the target node equipment in the mesh network can be determined through the external IP mapping table, and the MAC address of the target node equipment is determined through the internal IP mapping table; and the root node sends the IP data packet to the target node equipment through the MAC protocol.
It should be understood that in the method herein all IP packets sent from a node device are destined for the root node, and the destination MAC address is always the MAC address of the root node, so the node device does not need the ARP address translation protocol. And (4) finding a target route by the root node according to the maintained MAC address table of the mesh network equipment for forwarding the IP packet from the external network to the mesh layer of the mesh network until the packet reaches the target node equipment.
In addition, the method of the invention basically does not limit the number of the node devices in the mesh network and can support thousands of node devices. The IP address is bound with the node equipment, so that the external IP address is kept unchanged when the internal topology of the mesh network is changed.
The above embodiments have given specific operational procedures by way of example, but it should be understood that the scope of protection of the present invention is not limited thereto.
While various embodiments of various aspects of the invention have been described for purposes of this disclosure, it should not be understood to limit the teachings of the disclosure to these embodiments. Features disclosed in one particular embodiment are not limited to that embodiment, but may be combined with features disclosed in different embodiments. Further, it should be understood that the method steps described above may be performed sequentially, in parallel, combined into fewer steps, split into more steps, combined and/or omitted differently than as described. It will be understood by those skilled in the art that there are many more alternative embodiments and variations possible and that various changes and modifications may be made in the components and arrangements described above without departing from the scope of the present invention as defined in the appended claims.
