Description
Technical Field

At present, Mesh network is widely applied, mainly because the coverage of a traditional wifi router is limited, and the wifi coverage demand of many scenes is higher and higher. However, the existing Mesh networking scheme can only be used by a main control device to surf the internet, and each child node is used as a network bridge to perform signal expansion on the main control device, as shown in fig. 1, a wifi Mesh network is formed between the child node and a main control device CAP, and the backhaul between the child node and the main control device CAP can be 5.8G or 2.4G wifi or wired. In the existing mesh networking, for example, all the wireless terminal traffic flows connected to the child node C and the child node B are finally converged to the master control device CAP to get to the Internet. When many terminals access to the Mesh network, all internet data streams are sent out from the main control device, which inevitably results in an overload of the main control device and network congestion.
Since Mesh is mainly characterized by a seamless roaming technology, the existing wifi Mesh generally consists of a main route with a plurality of sub-routes, and the sub-routes cannot surf the internet and only expand signals of the main route. Therefore, the load of all the terminals goes through the sub-route to the main route for surfing the internet. When the access wireless terminal accesses the internet too much, the problems of network congestion caused by too heavy load of the main route, overlong data reaction delay and the like occur. The node failure can cause the failure of the networking network and even the breakdown of the whole networking, so that the application scene of the Mesh is greatly limited.

Example one
Fig. 2 is a schematic structural diagram of a distributed Mesh networking network according to an embodiment of the present invention. Referring to fig. 2, the distributed Mesh networking network according to the embodiment of the present invention specifically includes a master control device and a plurality of child nodes; wherein:
the main control equipment and the plurality of sub-nodes form a wireless grid network, the main control equipment is directly connected with an external network, and each sub-node is directly or indirectly connected with the external network through the main control equipment.
Specifically, because in traditional Mesh network, because main control equipment management data and service data concentrate together and can appear the too big problem that leads to the Mesh network congestion of load, consequently, in this application, every child node can all regard as the gateway, inserts the business data stream that outside mobile terminal realized the function of surfing the net and need not through main control equipment, lets main control equipment can be absorbed in Mesh network management or handle light-weight service data, is favorable to the management of Mesh network stability, child node and external network child node with main control equipment can be through 5.8G wireless technology, 2.4G wireless technology or wired connection, supports that the multinode surfs the net and can make Mesh network's coverage wider, and the node is more.
The following describes a load balancing scheduling method based on the number of internet access terminals in this embodiment. Specifically, as shown in fig. 3, the method includes:
step S110, monitoring the number of access terminals of each child node.
For example, the master device is connected with 3 child nodes: child node A, child node B, and child node C. The main control equipment monitors the number of access terminals of the child node A, the child node B and the child node C respectively, and monitors that 10 terminals are accessed to the child node A, 40 terminals are accessed to the child node B and 50 terminals are accessed to the child node C respectively. It can be understood that the number of access terminals of each child node monitored by the master control device may be a timing monitoring or an automatic reporting by the child node, for example, the timing monitoring may be that the child node reports terminal information once at a timing of 5 seconds; the automatic reporting of the child node may be that the child node triggers the terminal to join in a reporting event every time the terminal is accessed, the terminal leaves and also triggers the terminal leaving event, and the change of the number of the terminal of the node is maintained in real time through the event information main control device, and the like, which is not limited in this embodiment.
And step S120, determining a busy sub-node and an idle sub-node according to the number of each sub-node access terminal.
Specifically, the master control device counts the load conditions of the sub-nodes according to the load monitoring of different sub-nodes, and analyzes which node has idle flow and which node has busy flow. As an optional embodiment, the main control device pre-configures the maximum network access number of the bearer terminals of each child node, and may be configured through a web or a cloud. The main control equipment determines a busy sub-node and an idle sub-node according to the number of the access terminals of each sub-node, and the method comprises the following steps: the main control device calculates to obtain nodes with the number of the actually accessed internet access terminals larger than the number of the internet access terminals with the maximum preset load bearing terminal as busy sub-nodes, and calculates to obtain nodes with the number of the actually accessed internet access terminals smaller than the number of the internet access terminals with the maximum preset load bearing terminal as idle sub-nodes.
For example, the number of the maximum bearer terminals of each child node on the network is configured to be 25 in advance, and when the master control device monitors that 10 terminals of the child node a are accessed, 40 terminals of the child node B are accessed, and 50 terminals of the child node C are accessed, it is determined that the child node B and the child node C are busy child nodes, and the child node a is an idle child node.
As an optional embodiment, the main control device further monitors a traffic load of each child node in a preset period, and determines a busy child node and an idle child node according to the traffic load of each child node.
Step S130, the link address information of the idle sub-node is sent to the busy sub-node to control the busy sub-node to guide the terminal newly accessed from the busy sub-node to the idle sub-node.
Specifically, when the child node B and the child node C are determined to be busy child nodes and the child node a is idle child nodes, the link address information of the child node a is sent to the child node B and the child node C, and the child node B and the child node C can guide a later newly accessed terminal to the child node a with an idle load bandwidth to surf the internet. As shown in fig. 2, the external terminal is accessed from the child node C and surfs the internet through the link 1, and when the number of the internet-surfing terminals of the child node C increases gradually, the external terminal can be guided to the child node a or the main control device to surf the internet, that is, the external terminal surfs the internet through the link 2 or the link 3.
As an optional embodiment, the main control device further issues a guidance configuration file to the busy sub-node to control the busy sub-node to intercept a dhcp broadcast packet of a new access terminal, and the idle sub-node responds to the dhcp broadcast packet of the new access terminal to guide the new access terminal to an idle sub-node access network.
As an optional embodiment, the main control device is further configured to monitor the failed child node at regular time, and direct the internet access terminal that uses the failed child node as an access node to use a normal idle child node as the access node, or direct the newly accessed internet access terminal to the normal idle child node and then access the network.
Specifically, the sub-node that the master control device regularly monitors the fault includes: and the main control equipment judges whether the node fails according to the interface name of the default route of each child node and whether the gateway of the default route can ping.
The technical scheme of the embodiment of the invention is based on distributed Mesh networking, realizes that each sub-node can surf the internet and performs load balancing on the access terminal of each node, realizes that the terminal accessed to the Mesh network is guided to any sub-node to surf the internet, and realizes the load balancing of each node through three aspects of load monitoring, load analysis and flow guiding, thereby solving the problems of overlarge load of a single node and network congestion, and eliminating or avoiding the bottleneck of uneven load distribution of the existing network nodes and long data flow congestion reaction time. In addition, when any node fails or can not surf the internet, the terminal accessed to the failed node can be guided to the node with the relative idle bandwidth to surf the internet, the self-healing capability of the network is extremely strong, the stability of the mesh network is ensured, and the terminal service is not influenced by the failed node.
Example two
On the basis of the first embodiment, the distributed Mesh networking network of the embodiment of the invention can realize the same seamless roaming of the traditional Mesh networking while realizing the surfing of any child node, thereby greatly improving the stability and flexibility of the Mesh networking. The method comprises the following steps: when an access terminal accesses from a first sub-node of a first area, the first sub-node is set as a self-default gateway of the access terminal by a main control device, and all data packets sent to an external network are forwarded by the self-default gateway; when the access terminal roams to the second area, the access terminal still sends the data packet of the foreign network to the self-default gateway through other sub-nodes in the network and then forwards the data packet of the foreign network to the self-default gateway.
In this embodiment, the seamless roaming function of the Mesh is not affected by the equilibrium scheduling policy based on the number of the internet access terminals. After the terminal is switched to a new node, the destination link address of the terminal is still the original address of the guide node. As shown in fig. 4, when the number of access networks of the child node C is overloaded, the newly accessed user U will be guided to the child node a by the child node C to access the network, for example, the flow of the identification service of 1 is flowing. When the user U moves from the area of the sub-node C to the area of the sub-node B, the user U is wirelessly switched to the sub-node B because the link address of the user destination gateway is not changed, or the link MAC address of the sub-node A. Therefore, when the user U accesses the child node B, the traffic flow still flows from the identifier service of the child node a, such as 2. The whole service flow is uninterrupted, thereby realizing the function of seamless roaming of load balancing.
The detailed strategy implementation of surfing the internet and realizing seamless roaming by the child node of the embodiment is detailed below. As shown in fig. 4, firstly, the mobile phone first accesses the Mesh network, the child node a can surf the internet normally and is connected to the child node a, a normal DHCP flow is interacted, the child node a configures a firewall to intercept a DHCP discover broadcast message, the child node a processes a DHCP request of the mobile phone, the mobile phone obtains an IP and a DHCP server gateway allocated by the child node a, and thus, when the mobile phone requests to surf the internet, a data packet is directly surfed from the route of the child node a. When the mobile phone moves to be close to the child node B (the child node B can normally surf the internet), the master control device CAP node detects that the signal change can switch the mobile phone to be connected to the child node B, and the mobile phone is successfully connected to the child node B. And the connection of the sub-node B is completed, at the moment, under the condition that the lease time of the mobile phone end is not up, the IP address and the gateway information of the mobile phone cannot be changed, when the DHCP lease information needs to be updated, the mobile phone end actively sends a renew to update the DHCP information, at the moment, the sub-node B can release a corresponding request message, the message can finally obtain the response of the sub-node A, and the DHCP information is normally updated. At the moment, the data of the mobile phone end on the internet is sent to the sub-node A in the bridge, and then the data is routed from the sub-node A to the internet, so that the sub-node on the internet and seamless roaming are realized. If the child node a cannot normally go on the network due to a fault or a network disconnection, the child node a automatically forwards the data packet passing through the child node a, and goes on the network by other nodes (the node may be fixed as a main control device or designated by the main control device), thereby realizing node fault handling. And the child node carries out internet surfing judgment, and whether ping communication can be carried out according to the interface name of the default route and the gateway of the default route.
The technical scheme of the embodiment of the invention is based on distributed Mesh networking, realizes that each sub-node can surf the internet and balances the flow load of each node and the load of the node access terminal, realizes that any sub-node surfs the internet and can realize the same seamless roaming of the traditional Mesh networking, and greatly improves the stability and the flexibility of the Mesh networking. The bandwidth of the distributed Mesh networking nodes is enabled to have higher utilization rate, the services of the distributed Mesh nodes are balanced, and high time delay or interruption of the services caused by node congestion or faults is avoided, so that the effects of large-range coverage, terminal intercommunication in a network, seamless roaming, large bandwidth, low time delay and high reliability are achieved.
