Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Fig. 1 is a flow chart of a network access allocation method according to an embodiment of the present application; referring to fig. 1, the network access allocation method is applied to a router, which is any one of router nodes, and includes the steps of:
S100A: a first access request of a network device is received.
Specifically, the network device is a device to be accessed to the network. The network equipment can access the network through the router and the gateway in turn. The first access request of the network device is sent in broadcast form, so that each router in the router node can receive the first access request of the network device.
S200A: and acquiring a first residual accessible quantity from the first allowed access quantity table according to the first access request.
Specifically, taking one router in the router nodes as an example, after the router receives the first access request, the router obtains the first remaining accessible number of the current accessible device by searching a first allowed access number table of the router. The first remaining accessible number is a number of router remaining accessible devices.
The first allowed access number table characterizes a state of the corresponding router access device. The first allowed access number table may store an allowed amount of router accessible devices and an accessed amount of accessed devices.
The allowable amount of each router accessible device is set in advance by engineering personnel according to actual conditions.
The first allowed access number table may also store a current first remaining accessible number.
The step S200A specifically includes: and obtaining a first residual accessible quantity according to the difference value between the allowable quantity of the router accessible equipment and the accessed quantity of the accessed equipment in the first allowable access quantity table.
In another embodiment, the first allowed access number table stores a first remaining accessible number of routers, the first remaining accessible number being obtained by subtracting 1 from a current first remaining accessible number after each successful access to one network device, an initial value of the current first remaining accessible number being an allowed number of the router accessible devices.
S300A: and rejecting the first access request of the network device if the first remaining number of accessible devices is less than a first threshold.
Specifically, if the router knows through the table look-up that the current first remaining number of accessible devices is smaller than the first threshold, the router refuses the first access request of the network device.
The first threshold is a positive integer greater than or equal to 1.
If the first threshold is a positive integer greater than or equal to 2, the router denies the first access request of the network device even if the first remaining accessible number is not 0. This arrangement allows for emergency access channels to be reserved for each router to cope with emergency situations. For example, there are suddenly a large number of devices to access or there are emergency devices to connect, etc.
The setting of the first threshold value determines the reserved access quantity of the router, and the specific value can be set according to actual conditions.
In a specific embodiment, in order to ensure the communication quality and reduce unnecessary delay, a pre-selection rule may be set for each router, and the router in the router node obtains the communication distance with the network device, and if the communication distance is greater than the distance threshold, the first access request of the network device is refused.
In one embodiment, the method further comprises the steps of:
S400A: if the first residual accessible quantity is greater than or equal to a first threshold value, acquiring the current access states of other routers and network equipment in the router node within a first preset distance range;
S500A: if the current access states of the other routers and the network device are: and if no other router in the router nodes within the first preset distance range has established connection with the network equipment, establishing connection with the network equipment.
If the current access states of the other routers and the network equipment are: and if any other router in the router nodes within the first preset distance range has established connection with the network equipment, the connection with the network equipment is refused to be established.
Specifically, each router in the router node receives the first access request of the network device, so any router may first establish a connection with the network device. In order to avoid network confusion and resource waste caused by the fact that one network device is connected with a plurality of routers at the same time, each router needs to know whether other routers have established connection with the network device when acquiring that the router has residual access quantity. If no other router has established a connection with the network device, the router may establish a connection with the network device.
The first preset distance range is a communication distance range between the routers.
In one embodiment, the method further comprises the steps of:
S060A: updating a first allowed access quantity table after establishing connection with the network equipment;
S070A: updating the network device information into an accessed device management table;
S080A: and sharing the updated accessed device management table to the router node.
Specifically, each router has its own first allowed access number table and accessed device management table. The first allowed access number table and the accessed device management table may be stored in the corresponding router, or the first allowed access number table and the accessed device management table of all routers may be stored in a common storage area, so that all routers may share the first allowed access number table and the accessed device management table of all routers.
After the router establishes connection with the network device, the router updates the first allowed access quantity table of the router, and meanwhile, the information of the network device is stored and updated in the accessed device management table.
Each router in the router nodes can broadcast the updated current device access state to other routers in a sharing mode.
In a specific embodiment, each router may only obtain the current device access status of other routers within the preset distance range.
In a specific embodiment, the method further comprises the steps of:
S400A: if the first residual accessible quantity is greater than or equal to a first threshold value, acquiring the current access states of other routers and network equipment in the router node within a first preset distance range;
S500A: if the current access states of the other routers and the network device are: if no other router in the router node within the first preset distance range has established connection with the network equipment, acquiring a first residual accessible quantity of each other router in the router node within the first preset distance range;
S600A: comparing the first remaining accessible number of the router with the first remaining accessible number of each other router;
S700A: if the first residual accessible quantity of any one other router is higher than the first residual accessible quantity of the router, rejecting the first access request of the network equipment, and if the first residual accessible quantity of any one other router is not higher than the first residual accessible quantity of the router, establishing connection with the network equipment.
Specifically, if the router has a remaining accessible amount and no other router has been connected to the network device in the first preset range, the router compares the first remaining accessible amount of the router with the first remaining accessible amount of other routers in the first preset range, and if the first remaining accessible amount of the router is higher than the first remaining accessible amount of any one of the other routers in the first preset range, the router establishes a connection with the network device. If the first residual accessible number of any one other router exists in the first preset distance range is higher than the first residual accessible number of the router, the router refuses to establish connection with the network equipment.
The principle of small amount of priority allocation is realized through the embodiment. A small amount means a small number of accessed devices, meaning a large amount of unaccessed or remaining accessible. It is further achieved that the number of access devices per router is balanced.
In one embodiment, the method further comprises the steps of:
S400A: and if the first residual accessible quantity is greater than or equal to a first threshold value, acquiring the current access states of other routers and network equipment in the router node within a first preset distance range.
S500A: if the current access states of the other routers and the network device are: if no other router in the router nodes within the first preset distance range is connected with the network equipment, acquiring the communication feasibility of the router nodes and the network equipment;
wherein the communication feasibility is determined by the communication distance and/or the communication signal strength.
In particular, communication feasibility is used to characterize whether a router is suitable for a communication connection with a network device. The communication feasibility is determined by the communication distance and/or the communication signal strength of the router and the network device.
The farther the router is from the network device, the less suitable the router is for communication; the smaller the communication signal strength of the router with the network device, the less suitable for communication.
The communication feasibility may be inversely related to the communication distance, e.g. the communication feasibility is the inverse or negative of the communication distance.
The communication feasibility degree can also be in direct proportion to the communication signal strength.
The communication feasibility may also be a weighting of the communication distance and the communication signal strength.
S600A: a first remaining accessible number of each other router in the router node within a first preset distance range is obtained.
S700A: and selecting the router with the first residual accessible number larger than the first threshold value from other routers as a candidate router.
Specifically, the router may acquire a first remaining accessible number of other routers within a first preset distance range, and if there are routers with the first remaining accessible number greater than a first threshold, the router is used as a candidate router. The candidate router determines whether the router is more suitable for establishing a connection with the network device.
S800A: and acquiring the communication feasibility of each candidate router and the network equipment.
S900A: the communication feasibility of the router with the network device is compared with the communication feasibility of each candidate router with the network device.
S1000A: if the communication feasibility of any one candidate router and the network equipment is higher than the communication feasibility of the candidate router and the network equipment, rejecting a first access request of the network equipment; if the communication feasibility of any one candidate router with the network equipment is higher than the communication feasibility of the candidate router with the network equipment, the candidate router is connected with the network equipment.
Specifically, if the communication feasibility is inversely related to the communication distance, the router obtains the communication feasibility after taking the reciprocal or negative of the communication distance between itself and the network device.
If the communication feasibility is in direct proportion to the communication signal strength, the router takes the communication signal strength of the router and the network equipment as the communication feasibility.
If the communication feasibility is a weight of the communication distance and the communication signal strength, the router weights the communication distance and the communication signal strength of the router and the network equipment to obtain the communication feasibility.
The router compares the communication feasibility of the router with the communication feasibility of other candidate routers, and if any one of the candidate routers has the communication feasibility higher than the communication feasibility of the router and the network equipment, the router refuses the first access request of the network equipment; if the communication feasibility of any one candidate router with the network equipment is higher than the communication feasibility of the candidate router with the network equipment, the candidate router is connected with the network equipment.
According to the embodiment, the communication feasibility of each router and the network equipment is detected in advance from two dimensions of the communication signal intensity and the communication distance, so that the network equipment can be connected to a network with strong communication signals or a network with short delay and quick communication can be connected to the network, and the communication quality of the network equipment is guaranteed.
In one embodiment, prior to step S100A, the method further comprises the steps of:
S010A: sending a second access request to a gateway node comprising at least one gateway connected to a network;
S020A: receiving an authentication request of a target gateway responding to the second access request;
S030A: responding to the authentication request of the target gateway to establish communication with the target gateway.
Specifically, there is at least one gateway in the gateway node. The router also needs to establish a connection with a gateway in the gateway node to access the network. The router sends the second access request to the gateway node in the form of a broadcast. Thus, each gateway of the connected network can receive the second access request. But not every gateway will establish a connection with the router, but at most only one gateway will establish a connection with the router. If the target gateway responds to the second access request in the gateway node, the router establishes communication after mutual authentication with the target gateway. The authentication process specifically includes confirming whether the connection authority is available, whether the connection is illegal through encryption and decryption technology, and the like. The authenticated content may include: the process is an identity intercommunication before the two parties establish communication.
Fig. 2 is a flow chart of a network access allocation method according to an embodiment of the present application; referring to fig. 2, the network access allocation method is applied to a gateway, which is a gateway of any one connected network in gateway nodes, and the method includes the following steps:
S100B: receiving a second access request of the router to be accessed;
S200B: acquiring a second residual accessible quantity from a second allowed access quantity table according to the second access request;
S300B: if the second remaining accessible quantity is smaller than a second threshold value, rejecting a second access request of the router to be accessed;
the second allowed access number table characterizes the state of the corresponding gateway access router.
Specifically, the router can access the network through the gateway. The second access request of the router is sent in broadcast form, so that each of the gateway nodes can receive the second access request of the router.
Taking a gateway in the gateway node as an example, after the gateway receives the second access request, the gateway obtains a second residual accessible number of the current accessible router by searching a second allowed access number table of the gateway. The second remaining number of accessible routers is the number of gateway remaining accessible routers.
The second allowed access number table characterizes the state of the corresponding gateway access router. The second allowed access number table may store an allowed amount of gateway accessible routers and an accessed amount of accessed routers.
The second allowed access number table may also store a current second remaining accessible number.
The allowable amount of each gateway accessible router is set by engineering personnel according to actual conditions in advance.
The step S200B specifically includes: and obtaining a second residual accessible quantity according to the difference value between the allowable quantity of the gateway accessible router and the accessed quantity of the accessed router in the second allowable access quantity table.
In another embodiment, the second allowed access number table stores a second remaining accessible number of gateways, the second remaining accessible number being obtained by subtracting 1 from a current second remaining accessible number after each successful access to one router, an initial value of the current second remaining accessible number being an allowed number of routers accessible to the gateway.
S300B: and if the second remaining accessible number is smaller than the second threshold, rejecting the second access request of the router.
Specifically, if the gateway knows through the table lookup that the current second remaining accessible number is smaller than the second threshold, the gateway refuses the second access request of the router.
The second threshold is a positive integer greater than or equal to 1.
If the second threshold is a positive integer greater than or equal to 2, the gateway denies the second access request of the router even if the second remaining accessible number is not 0. This arrangement allows for emergency access channels to be reserved for each gateway to cope with emergency situations. For example, there are suddenly a large number of routers to access or there are emergency devices to connect, etc.
The setting of the second threshold value determines the reserved access quantity of the gateway, and the specific value can be set according to actual conditions.
In a specific embodiment, in order to ensure the communication quality and reduce unnecessary delay, a pre-selection rule may be set for each gateway, and the gateway in the gateway node obtains the communication distance between the gateway node and the router, and if the communication distance is greater than the distance threshold, the second access request of the router is refused.
In one embodiment, the method further comprises the steps of:
S400B: if the second residual accessible quantity is greater than or equal to a second threshold value, acquiring the current access states of other gateways in the gateway node and the router to be accessed within a second preset distance range;
S500B: if the current access states of the other gateways and the router to be accessed are: and if no other gateway in the gateway node within the second preset distance range is connected with the router to be accessed, the connection is established with the router to be accessed.
If the current access states of the other gateways and the router to be accessed are: and if any other gateway exists in the router node within the second preset distance range and is connected with the router to be accessed, the connection with the router to be accessed is refused.
Specifically, if the current access states of the other gateways and the router are: and if any other gateway in the gateway node within the second preset distance range has established connection with the router, the connection with the router is refused to be established.
Specifically, each gateway in the gateway node receives the second access request of the router, so any gateway may first establish a connection with the router. In order to avoid network confusion and resource waste caused by the fact that one router is connected with a plurality of gateways at the same time, each gateway needs to know whether other gateways have established connection with the router when acquiring the residual access quantity of the gateway. If no other gateway has established a connection with the router, the gateway may establish a connection with the router.
The second preset distance range is a communication distance range between the gateways.
In one embodiment, the method further comprises the steps of:
S400B: if the second residual accessible quantity is greater than or equal to a second threshold value, acquiring the current access states of other gateways in the gateway node and the router to be accessed within a second preset distance range;
S500B: if the current access states of the other gateways and the router to be accessed are: if no other gateway in the gateway node within the second preset distance range is connected with the router to be accessed, obtaining a second residual accessible quantity of each other gateway in the gateway node within the second preset distance range;
S600B: comparing the second remaining accessible number of the gateway with the second remaining accessible number of each other gateway;
S700B: if the second residual accessible quantity of any one other gateway is higher than the second residual accessible quantity of the other gateway, rejecting the second access request of the router to be accessed, and if the second residual accessible quantity of any one other gateway is not higher than the second residual accessible quantity of the other gateway, establishing connection with the router to be accessed.
Specifically, if the gateway has a remaining accessible amount and no other gateway has been connected to the router to be accessed in the second preset range, the gateway compares the second remaining accessible amount of the gateway with the second remaining accessible amount of other gateways in the second preset distance range, and if the second remaining accessible amount of the gateway is higher than the second remaining accessible amount of any other gateway in the second preset distance range, the gateway establishes connection with the router to be accessed. If the second residual accessible number of any one other gateway exists in the second preset distance range is higher than the second residual accessible number of the gateway, the gateway refuses to establish connection with the router to be accessed.
The principle of small amount of priority allocation is realized through the embodiment. A small number means that the number of accessed routers is small, meaning that the amount of unaccessed or the remaining accessible amount is large. Further balancing the number of access routers per gateway is achieved.
In one embodiment, the method further comprises:
S060B: updating a second allowed access quantity table after establishing connection with the router to be accessed;
S070B: updating the router information to be accessed into an accessed router management table;
S080B: and sharing the updated accessed router management table to the gateway node.
Specifically, each gateway has its own second allowed access number table and accessed router management table. The second allowed access number table and the accessed router management table may be stored in the corresponding gateway, or the second allowed access number table and the accessed router management table of all gateways may be stored in a common storage area, so that all gateways may share the second allowed access number table and the accessed router management table of all gateways.
After the gateway establishes connection with the router to be accessed, the second allowed access quantity table is updated, and meanwhile, the information of the router to be accessed is stored and updated into the accessed router management table.
Each gateway in the gateway node can broadcast the updated current router access state to other gateways in a sharing mode.
In a specific embodiment, each gateway may only obtain the current router access status of other gateways within the preset distance range.
In one embodiment, an embodiment of the present application provides a network access allocation method, applied to a network device, including the following steps:
sending a first connection request to a router node;
receiving an authentication request of a target router responding to the first connection request;
responding to the authentication request of the target router to establish a communication connection with the target router.
It should be understood that, although the steps in the flowcharts of fig. 1 and 2 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 1 and 2 may include multiple sub-steps or phases that are not necessarily performed at the same time, but may be performed at different times, nor does the order in which the sub-steps or phases are performed necessarily occur sequentially, but may be performed alternately or alternately with at least a portion of the sub-steps or phases of other steps or other steps.
Fig. 3 is a block diagram of a network access allocation system according to an embodiment of the present application; referring to fig. 3, the network access allocation system includes: a gateway node comprising a plurality of gateways connected to the network, and a router node comprising a plurality of routers;
any gateway is used for receiving a second access request of the router to be accessed, acquiring a second residual accessible quantity from a second allowed access quantity table according to the second access request, and if the second residual accessible quantity is greater than or equal to a second threshold value and no other gateway in the gateway nodes within a second preset distance range is connected with the router to be accessed, establishing connection with the router to be accessed;
and any router is used for receiving a first access request of the network equipment, acquiring a first residual accessible quantity from an allowed access quantity table according to the first access request, and if the first residual accessible quantity is greater than or equal to a first threshold value and no other router in the router nodes within a first preset distance range is connected with the network equipment, establishing connection with the network equipment.
In one embodiment, the networking mode of the network access distribution system of the present application is a Mesh networking mode. The router is a mesh router, and the gateway is a mesh gateway. Of course, the present application is not only applied to a network communication system of mesh networking, but also to a network communication system of networking in other manners.
The mesh networking has the characteristic of strong independence, so that the gateway node and the router node do not influence the normal operation of the network, the stability of the network is improved, and the whole network cannot be used because one router is damaged. The only disadvantage is that too many devices are accessed by the router, which results in a reduced user network speed experience. Since the devices that each router can access are limited, how to intelligently allocate the number of access devices is an important issue.
Mesh networking has been slowly entering into community, home, enterprise networks. When the gateway router and the gateway are connected, a network device and a bridge of the network connection are formed, and due to the plurality of devices, routers near the access device are required to be matched and connected to the network. However, a large number of gateway routers are deployed to cause cost increase and influence on network resource allocation, so that Mesh routers are added to serve as access points to nearby devices, that is, the devices only need to be connected with the Mesh routers, but excessive access Mesh routers influence the user network speed experience. The network access distribution system is used for distributing the access quantity of the router and the network equipment. This is divided into gateway nodes and router nodes. Each node is respectively allocated with an allowed access quantity table for each router and gateway, and each time the router is to be accessed to the network equipment or the router is to be accessed to the gateway, the router or the gateway can determine whether to accept the access request or not through table lookup, thereby realizing intelligent network access allocation.
The method and the device solve the problem of intelligent distribution of the router by adopting a mesh networking mode. mesh networking is just like a massive spider network. Each mesh router acts as a node in the network. Intelligent allocation is achieved by adding an allowed access number table in each node. The number of the access devices of each router and the number of the access routers of each gateway can be controlled through the method and the device, so that the network speed experience is guaranteed and improved. The trouble that the network speed of the network equipment is too slow or the experience of the network speed is influenced because of too many router access devices or too many gateway access routers is reduced as much as possible.
