Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying figures are described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
Mesh is a network coverage technology, which can expand the coverage of a user network, and can ensure that the network service in the user environment is normal as much as possible and the network coverage has no dead angle compared with the coverage of a single device; compared with the traditional relay and extender modes, the roaming effect of the wireless signals of the user among the access devices can be ensured to be low delay and high bandwidth, and the internet experience is improved. In the existing Mesh device communication method, a communication link, namely a return link, between Mesh devices is either wired, or Wi-Fi 2.4G or Wi-Fi 5G/6G, and cannot transmit data through 2 links at the same time. Therefore, it is difficult for the prior art to fully utilize the bandwidth of the MESH device, and therefore the bandwidth of the network on the slave device is often limited by the bandwidth of the backhaul link.
In a first embodiment of the wireless mesh network backhaul link allocation method of the present application, referring to fig. 1, the wireless mesh network backhaul link allocation method includes:
step S10, after the wireless grid network is successfully networked, establishing each return link between a network node in the wireless grid network and a superior device of the network node;
step S20, based on the types of the service flows received from the terminal, the priority of each service flow is divided;
step S30, according to the type, network quality and residual bandwidth of each return link, dividing the priority of each return link;
step S40, based on the priority of each service flow and the priority of each backhaul link, allocating each service flow to a corresponding backhaul link.
In this embodiment, it should be noted that, each network node is included in the wireless Mesh network (Mesh), when a user performs network communication, there is a network node as a node that directly performs direct communication with a terminal device of the user, and other network nodes are standby or transit nodes, the network node in step S10 is a node that is directly connected to the terminal device of the user, and the upper-level device may be a group control device connected to the network node or other transit network nodes, and is configured to receive and process a packet sent from the terminal device to the network node; when each return link is established between the Network node and the superior device, a separate VALN is allocated to each return link through a Virtual Local Area Network (VLAN) technology, so as to avoid mutual interference between each return link during data transmission; the return link comprises a wired return link and a wireless return link, namely a WiFi return link, and comprises a 2.4G frequency band and a 5G frequency band.
As an example, steps S10 to S40 include: when successful Mesh networking is detected, performing configuration synchronization based on a configuration synchronization process and a protocol specification of a Mesh protocol to obtain Back hash (backhaul link) information corresponding to each backhaul link, wherein the Back hash information comprises SSID (wireless network identifier), passwords and encryption modes of the 2.4G frequency band backhaul link and the 5G frequency band backhaul link; establishing each return link between a network node in the wireless mesh network and superior equipment of the network node based on the Back haul information, and allocating an independent virtual network segment for each return link through a VLAN technology; determining the priority of each service flow based on the type of the service flow sent by the terminal equipment connected with the network node and a mapping table of the type and the priority of the preset service flow; the priority of each return link is divided according to the type, the network quality and the residual bandwidth of each return link, wherein the priority of the wired return link is higher than that of the wireless return link, the higher the priority of the return link is, the higher the network quality is, the higher the priority of the return link is, and the higher the residual bandwidth is, the higher the priority of the return link is; distributing the service flow with the highest priority in each service flow to the return link with the highest priority for sending; updating the priority of a return link in real time, and sequentially distributing each service flow to the return link with the highest current priority for sending according to the priority of each service flow.

In this embodiment of the present application, it should be noted that each backhaul link includes a wired backhaul link and a wireless backhaul link, and referring to fig. 2, in practice, the wired backhaul link and the wireless backhaul link may be simultaneously reserved, and if the network node (Agent 1) and the superior device (Controller/Agent) simultaneously maintain wired connection and bandwidth meets the requirement, only the wired backhaul link (Ethernet ) may be reserved; the Virtual Local Area Network (VLAN) technology is a network segmentation technology which is not limited by the physical location of a network user and is performed according to the user requirement, that is, a separate VLAN is allocated to each backhaul link to realize broadcast domain isolation between different VLANs and prevent loops from being generated, for example, by using a VLAN aggregation method, super-VLAN and Sub-VLAN technologies can be used for processing multi-link Back hue. Sub-VLANs can be used to isolate broadcast domains and Super-VLANs for VLAN aggregation. And the Sub-VLAN is associated to the corresponding super-VLAN, the Sub-VLAN data is aggregated by the super-VLAN, and if needed, the super-VLAN allows one ip network segment to be used for a plurality of VLANs.
As an example, steps S11 to S13 include: after the networking of the Mesh specification is successful, executing a configuration synchronization process and a protocol specification based on a Mesh protocol corresponding to the Mesh networking so as to ensure data synchronization; acquiring back haul information respectively corresponding to the 2.4G frequency band and the 5G frequency band, such as a network name, an encryption mode and a password of a network; establishing a 2.4G frequency band return link and a 5G frequency band return link between the network node and the superior equipment of the network node based on the back haul information; and carrying out data distribution on the 2.4G frequency band return link and the 5G frequency band return link through a VLAN technology so as to isolate broadcast domains among the return links and prevent mutual interference.

In this embodiment, it should be noted that the correspondence rule is pre-established according to the importance degree between the service flows, so that when receiving the service flow data sent by the terminal device, the correspondence rule is called to query the priority of the service flow.
As one example, steps S21 to S22 include: calling a corresponding rule of the type and the priority of the service flow from a preset storage space; marking each service flow with a corresponding priority label based on the corresponding rule and the type of each service flow; and determining the distribution sequence of the return link of each service flow according to the priority label of each service flow, thereby ensuring the key service experience of the user.
Wherein, each of the service flow types at least includes a service flow related to a network protocol, a real-time service, an application service and a data transmission service, and before the step of obtaining a rule corresponding to the service flow type and the priority, the method further includes:
step A10, marking the service flow with the service flow type related to the network protocol as a first priority, wherein the network protocol at least comprises one of a domain name resolution protocol, a dynamic host configuration protocol and a point-to-point protocol transmitted by Ethernet;
