Based on the hardware architecture of the distributed routing device, the invention provides a mesh wired ad hoc network method, aiming at solving the problems of high production cost and poor user experience of a mesh networking device manufacturer.
As shown in fig. 2, fig. 2 is an embodiment of a mesh wired ad hoc network method according to the present invention, where the mesh wired ad hoc network method includes the following steps:
and S110, when the router detects the wired connection, periodically broadcasting networking request information.
Specifically, in the mesh network, a master is connected to the internet, and a slave is connected to the master. Therefore, when mesh networking is performed, at least one router needs to be connected to the internet (i.e., a wide area network or an extranet) in a wired manner (i.e., a network cable), and other routers in the mesh networking are directly or indirectly connected to the router connected to the internet through the network cable. If the router detects the wired connection, the mesh networking is started. At this time, each router in the network broadcasts the networking request information periodically. In this case, the networking request information broadcast by one router can be simultaneously received by a plurality of routers wired thereto. For example, when mesh networking is performed, if router a is connected to the internet and router B is connected to router a, router C may be connected to router a or router B. The networking request information of router a can be received by router B, and the networking request information broadcast by router B can also be received by router a.
And S120, when the router receives networking request information in the network, judging the identity information of the router, wherein the factory identity information of each router is set as a temporary host.
Specifically, the temporary host refers to that the identity information of each router used for mesh networking is not determined, that is, the host and the slave are not specified in the router of mesh networking when the router leaves the factory. Therefore, when the manufacturer leaves the router for mesh networking, the router does not need to be paired in advance, and the time cost and the labor cost of the manufacturer can be saved. When mesh networking is carried out, the router in the network can receive the networking request information broadcast by other routers while broadcasting the networking request information. Therefore, after the router receives the networking request information, the router starts to judge the identity information of the router, wherein the identity information comprises the temporary host, the permanent host and the permanent sub-machine.
S130, if the identity information of the router is the temporary host, whether networking can be performed is detected.
Specifically, if the identity information of the router receiving the networking request information is the temporary host, the router starts to detect whether the router can perform networking. The factory identity information of each router is set as a temporary host, and meanwhile, each router can receive networking request information in the network. Therefore, when mesh networking is performed for the first time, the identity information of each router receiving the networking request information is a temporary host.
And S140, if yes, changing the identity information of the user from the temporary host to the permanent host, and feeding back reply information when networking request information in the network is received.
Specifically, if the router whose identity information is the temporary host receives the networking request information and the router can be networked (i.e., access to the network), the router changes its own identity information to the permanent host to complete the automatic designation of the host. After the host computer is determined, the host computer feeds back reply information when receiving networking request information in the network, and the reply information is used for enabling the sub computer to acquire an IP (even if the sub computer can surf the internet) so as to complete the establishment of the mesh network. The host can feed back reply information to different routers in sequence or simultaneously according to the received networking request information.
S150, if the router is not networked, when the router receives reply information in the network, the identity information of the router is changed from the temporary host machine to the permanent sub machine.
Specifically, if the router of the temporary master identity is not connected to the network when receiving the networking request message, the router cannot become the master, and if the router receives a reply message from the network (the reply message is from the master), the router changes its own identity information from the temporary master to the slave, thereby completing the automatic designation of the slave.
It can be understood that, when mesh networking is performed for the first time, the identity information of each router in the network is a temporary host, and the router can receive networking request information, and meanwhile, based on the characteristic that the host in the mesh network has to directly access the internet (wide area network), the router can be set as: when the networking request information is received, if the identity information of the user is a temporary host and can be networked, the identity information of the user is changed from the temporary host to a permanent host, and after the identity information is changed to the permanent host, the reply information is fed back when the networking request information is received; and when the networking request information is received, if the identity information of the user is the temporary host and the networking cannot be performed, changing the identity information of the user from the temporary host to the permanent slave after the reply information is received.
Therefore, when a user performs mesh networking for the first time, the identity information of the router can be automatically changed into a permanent host or a permanent sub-machine, so that the host and the sub-machine in the router are not required to be manually appointed by the user, the flow of the mesh networking is greatly simplified, the use by the user is facilitated, and the use experience of the user can be improved.
It should be noted that, because the identity information of the slave unit is determined based on the reply information fed back by the host unit, when mesh networking is performed, it can be ensured that the host unit is determined first and then the slave unit is determined, thereby reducing the error condition during mesh networking and improving the stability during networking.
In summary, the mesh wired ad hoc network method of the present application sets the factory identity information of the router of the mesh network as a temporary host, and sets the router as: when the networking request information is received, if the identity information of the user is a temporary host and can be networked, the identity information of the user is changed from the temporary host to a permanent host, and after the identity information is changed to the permanent host, the reply information is fed back when the networking request information is received; and when the networking request information is received, if the identity information of the user is the temporary host and the networking cannot be performed, changing the identity information of the user from the temporary host to the permanent slave after the reply information is received. Therefore, when the user performs mesh networking for the first time, the identity information of the router can be automatically changed into a permanent host or a permanent sub-machine, and the host and the sub-machine in the router do not need to be manually specified by the user. Therefore, compared with common mesh networking equipment, the mesh wired ad hoc networking method does not need a manufacturer to pre-match a router when leaving a factory, and does not need a user to manually specify a host machine and a sub machine when networking, so that the production cost of the mesh component is reduced, the matching process of the mesh networking is simplified, and the user experience is improved.
Specifically, after receiving the networking request information, the router judges whether networking is possible or not by detecting the state of the WAN port of the router and whether a network protocol (IP) can be acquired or not. And when the WAN port state of the router is up and the IP address can be acquired, judging that the router can be networked. Otherwise, the network cannot be connected. The router can judge whether the router can be networked or not by simultaneously detecting the state of a WAN port and acquiring two conditions of whether a network protocol (IP) can be acquired or not, so that errors can be reduced, and the accuracy of networking judgment is improved.
It should be noted that only when the router is capable of accessing the internet, the identity information of the router is changed from the temporary host to the host, so that the mesh network completed by networking can be ensured to normally receive and transmit wireless data, the situation that networking is completed but internet surfing is unavailable is avoided, and user experience is improved.
As shown in fig. 3, in an embodiment, the mesh wired ad hoc network method further includes, if the router whose identity information is the temporary host receives the networking request information in the network, before detecting whether networking is possible, the router performs the steps of:
s240, detecting whether the networking request information in the network is from the local area network interface of the network, if so, detecting whether networking can be performed.
Specifically, when mesh networking is performed, when the router of the temporary host identity receives networking request information, before whether networking is possible is detected, whether the networking request information is from a local area network interface (namely a LAN interface) of the router is detected, and if so, whether networking is possible is detected. This is because if the networking request message is from a wide area network interface (i.e., WAN port) of the router (i.e., the networking request message is not from a LAN port of the router), it indicates that the router sending the networking request message is connected to the router receiving the networking request message through the switch (or other bridging device). At this time, if the router receiving the networking request information can access the internet, the router transmitting the networking request information can also access the internet through the switch. Then, in order to save network resources and guarantee the network quality of a wireless local area network in which two routers are independently manufactured, networking is not performed between two or more routers that are both connected to a switch (or other bridging device).
As shown in fig. 4, in an embodiment, the mesh wired ad hoc network method further includes:
s330, if the identity information of the router is the permanent host, feeding back reply information when the router receives networking request information in the network.
Specifically, after mesh networking is performed for the first time, a router serving as a host is determined, and the mesh networking is completed. At this time, if the user needs to expand the network, a new router can be accessed in the existing mesh network. After the newly accessed router is accessed to the mesh network, the newly accessed router broadcasts networking request information, and because the sub-machines in the mesh network need to interact with the host machine to be capable of being assembled into the network, the networking request information broadcasted by the newly accessed router is finally received by the host machine router. When the host router receives the networking request information, the host router feeds back reply information based on the received networking request information. The host router feeds back reply information to different routers in sequence or simultaneously according to the received networking request information. After receiving the reply information fed back by the host router, the newly accessed router changes the identity information of the newly accessed router from the temporary host to the sub-machine, and then the newly accessed router is combined into the existing mesh network to complete the expansion of the mesh network. It can be understood that after the host is determined, the identity of the slave machine of the router newly combined into the mesh network can be determined through the reply information fed back by the host router, so that when the mesh network is expanded, the router does not need to be limited to a specific slave machine router, and the expandability of the mesh network can be increased.
As shown in fig. 5, in an embodiment, the mesh wired ad hoc network method further includes, if the identity information of the router is a permanent host, when the router receives the networking request information, before feeding back a reply information, performing the steps of:
s430, detecting whether the networking request information comes from the local area network interface of the networking request information, and if so, feeding back reply information.
Specifically, when the mesh network is expanded, when the host receives the networking request information, before feeding back the reply information, it is detected whether the networking request information is from its own local area network interface (i.e., LAN interface), and if so, the reply information is fed back. This is because if the networking request message is from the wide area network interface (i.e., WAN port) of the router (i.e., the networking request message is not from the LAN port of the router), it indicates that the router sending the networking request message is connected to the host through the switch (or other bridging device). At this time, the router that transmits the networking request information can access the internet through the switch. Then, in order to save network resources and ensure the network quality of the wireless local area network which is independently manufactured by the two routers, the identity information of the newly accessed router is still kept as a temporary host, that is, the newly accessed router is rejected to be combined into the existing mesh network.
As shown in fig. 6, in an embodiment, the mesh wired ad hoc network method further includes:
s530, if the identity information of the router is a permanent sub-machine, when the router receives the networking request information, the networking request information is forwarded to the router of which the identity information is a permanent main machine, and the identity information of the router is kept unchanged.
Specifically, when a user accesses a new router in an existing mesh network to expand the mesh network, the newly accessed router may be directly connected to a router whose identity information is a permanent master or to a router whose identity information is a permanent slave. If the router which is newly accessed is directly connected with the router of which the identity information is the permanent host, the networking request information broadcasted by the router which is newly accessed can be directly received by the router of the host; if the newly accessed router is connected with the router with the identity information of the permanent sub-machine, the sub-machine forwards the networking request information to the main machine and keeps the identity information of the sub-machine unchanged. After receiving the networking request information, the host feeds back reply information based on the received networking request information. The network connection request information of the newly accessed router is forwarded by the sub-machine, and the newly accessed router does not need to be limited to be in wired connection with the host router when the mesh network is expanded, so that convenience in expanding the mesh network is improved, and a user can conveniently expand the network.
As shown in fig. 7, in an embodiment, the mesh wired ad hoc network method further includes:
s600, if the identity information of the router is a permanent sub-machine, when the router receives the reply information, the identity information of the router is unchanged.
Specifically, when the identity information of the router is the temporary host, the router changes the identity information of the router into a permanent sub-machine after receiving the reply information; and when the identity information of the router is the permanent sub-machine, the identity information of the router is unchanged after the router receives the reply information. Therefore, identity information of the submachine does not need to be set again, and rapid network expansion is facilitated.
In one embodiment, when a wired connection is detected, the router sends the networking request information to its wide area network interface and local area network interface simultaneously. Through the arrangement, the wide area network interface and the local area network interface of each router can perform information interaction, so that mesh networking can be performed no matter the network cable is plugged in the wide area network interface or the local area network interface, and convenience in networking of users is greatly facilitated. It should be noted that, based on the characteristics of the router, in order to be able to construct a mesh network, the router connected to the internet is connected to the internet through a wide area network interface.
In addition, the invention also provides a distributed routing device, which comprises at least two routers used for mesh networking, wherein the distributed routing device performs networking by using the mesh wired ad hoc networking method according to any embodiment.
In addition, the embodiment of the present invention further provides a computer-readable storage medium, which may be any one of or any combination of a hard disk, a multimedia card, an SD card, a flash memory card, an SMC, a Read Only Memory (ROM), an Erasable Programmable Read Only Memory (EPROM), a portable compact disc read only memory (CD-ROM), a USB memory, and the like.
