Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the 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.
It should be noted that references in the specification of the present application to the terms "comprises" and "comprising," and variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Some of the words that appear in the text are explained below:
(1) mesh networking: that is, "wireless mesh network", is a "multi-hop" (multi-hop) network, is developed from an ad hoc network, and is one of the key technologies to solve the "last mile" problem. In the process of evolving to the next generation networks, wireless is an indispensable technology. The wireless MESH can be cooperatively communicated with other networks, is a dynamic and continuously expandable network architecture, and any two devices can be wirelessly interconnected. The wireless MESH router forms a self-organizing network in a multi-hop interconnection mode, and provides higher reliability, wider service coverage and lower early investment cost for WMN networking.
(2) Physical Address (Media Access Control Address, MAC Address): also known as the mac Address, also known as the local area network Address (LAN Address), the Ethernet Address (Ethernet Address), is an Address used to identify the location of a network device. In the OSI model, the third layer network layer is responsible for IP addresses and the second layer data link layer is responsible for MAC addresses. The MAC address is used to uniquely identify a network card in the network, and if one or more network cards exist in a device, each network card needs to have a unique MAC address.
(3) Spanning Tree Protocol (STP): the method is applied to the establishment of the tree topology structure in the computer network, and mainly has the function of preventing redundant links in the network bridge from forming loop work. But certain factors may cause STP to fail and troubleshooting may be very difficult depending on the network design. The spanning tree protocol is suitable for network equipment of all manufacturers, and has difference in configuration and embodied function strength, but the principle and application effect are consistent. The basic principle of STP is to determine the topology of the network by passing a special Protocol packet, Bridge Protocol Data Unit (BPDU), between switches. There are two types of BPDUs, configuration BPDU (configuration BPDU) and TCN BPDU. The former is used to compute a loop-free spanning tree, and the latter is used to generate a refresh time (shortened from 300s by default to 15s) for shortening the MAC entry when the two-layer network topology changes.
MESH networking is a pure wireless MESH networking. When the whole network is composed of pure wireless MESH links, if a wired LAN link is added on the basis, for example, in the MESH networking shown in fig. 4, an AP2 node is added, and an AP2 node LAN port is connected with an existing AP1 node to obtain the MESH networking shown in fig. 2; or when the MESH networking shown in fig. 1 is performed, the AP1 and the AP2 node are connected by using the wired LAN link, so as to obtain the MESH networking shown in fig. 2, the LAN link and the MESH link exist simultaneously, and the broadcast message is repeatedly forwarded indefinitely on the LAN link and the MESH link, which causes a broadcast storm and affects normal networking and internet access services.
The existing loop prevention technology starts the STP function: during wired and wireless hybrid detection, after the loop is identified to exist, the MESH interface of the equipment with the small MAC address is blocked. That is, the MESH links between the device and all other devices are blocked, which may cause that other APs cannot access the MESH network through the device, and the AP device that has joined the network drops.
For example, the MESH networking shown in fig. 2 can be obtained by connecting a wire to the existing MESH networking shown in fig. 1, for example, connecting AP1 and AP2 by a wire. Under the function of STP, the MESH interface of AP1 is blocked; resulting in disconnection of links 4 and 5, disconnection of networking by AP4, and access of AP3 to the network only through AP2, resulting in MESH networking as shown in fig. 3.
When the existing networking is stable, the existing MESH networking shown in fig. 3 is disconnected from the wire, for example, the wired connection between the AP1 and the AP is disconnected, then the MESH connection between the AP1 and the AP2 is performed, and in the connection process, the MESH interface of the AP1 needs to perform a specific step, such as blocking- > listening- > learning- > forwarding, which generally needs more than 30 s.
When the existing networking is stable, wired devices are added to the existing MESH networking shown in fig. 4, for example, a new device AP2 is added, a LAN port of AP2 is connected to AP1 and powered on, and MESH connections of AP1 and AP2 form a loop, and under the function of STP, the effect is as shown in fig. 3.
Therefore, the existing loop prevention technology is not only easy to affect normal services due to abnormal disconnection of the access points, but also generally needs more than 30 seconds to reestablish wireless link connection when the two access points are switched to the wireless link from the link, which is long in time consumption and low in efficiency.
When the related technology is used for preventing loops in wired and wireless hybrid networking, normal services influencing an access point are easily influenced, and wired and wireless switching is slow, so that the efficiency of the hybrid networking is not high.
In order to solve the existing technical problem, the embodiment of the application provides a control method for a wired and wireless hybrid networking, if a current access point receives a first multicast message frame sent by a first access point through a wired network interface and determines that the first access point is a direct connection neighbor of the current access point, a first wireless link between the current access point and the first access point is disconnected; and after a first set time length, reestablishing the connection of the first wireless link. When the loop is detected during the wired and wireless hybrid networking, the wireless link in the loop is controlled to be reestablished after the wireless link is disconnected for the first set time, so that the normal service of an access point is prevented from being influenced, and the efficiency of the hybrid networking can be improved.
The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
The embodiment of the application provides a control method for wired and wireless hybrid networking, as shown in fig. 5, comprising the following steps:
step S501, if the current access point receives a first multicast message frame sent by the first access point through the wired network interface and the first access point is determined to be a direct connection neighbor of the current access point, disconnecting a first wireless link between the current access point and the first access point.
The direct connection neighbor is an access point which is directly connected with the current access point through a wireless link.
The following embodiments of the present application are all described by taking the current access point as the access point AP1 in fig. 1, and the first access point as the access point AP2 in fig. 1 as an example. The first multicast message frame may be a BPDU frame sent by the AP2 to the AP1, which is denoted as BPDU 01.
When the AP1 receives the first multicast packet frame BPDU01 sent by the AP2, the current access point AP1 first confirms whether the BPDU01 is a LAN port frame. Specifically, the AP1 determines whether the BPDU01 is a LAN port frame by determining whether the BPDU01 is received over a wired network interface. When the current access point AP1 receives a first multicast message frame BPDU01 sent by a first access point AP2 through a wired network interface, the BPDU01 is a LAN port frame; otherwise, the BPDU01 is not a LAN port frame.
If the current AP1 has determined that the first multicast packet frame BPDU01 sent by the first AP2 is received through the wired network interface, it is determined whether the first AP2 is a direct connection neighbor of the current AP 1.
In fig. 1, AP1 and AP3 are direct neighbors of AP2, and AP4 and AP2 are indirect neighbors. In the embodiment of the application, each access point stores a direct connection neighbor list of the access point. The current access point AP1 may detect whether the direct connection neighbor list of AP1 includes the MESH interface MAC of AP2, and if the MESH interface MAC of AP2 is detected, AP2 is a direct connection neighbor of AP 1. The direct connection neighbor list of the AP1 includes the MESH interfaces MAC of the access points directly connected to the current access point AP1 via the wireless link.
If the first access point AP2 is a direct neighbor of the current access point AP1, the first wireless link between the current access point AP1 and the first access point AP2 is disconnected. At this time, the first wireless link between the current access point and the first access point is link 2 in the MESH networking shown in fig. 2.
Step S502, after a first set time period, reestablishing the connection of the first wireless link.
Illustratively, in some embodiments of the present application, by extending the STP message content, a MAC address field M1 is added for holding the MAC address of the MESH interface. When the access point sends and forwards the BPDU, the MESH interface MAC of the self device is updated to the M1 field of the BPDU. When the current access point AP1 receives the BPDU01 transmitted by the AP2 of the LAN port, it detects the M1 field of the BPDU01, and detects whether there is a MESH interface MAC of the AP2 in the neighbor list directly connected to the MESH interface of the AP 1. If the MESH interface MAC of AP2 is detected, the MESH link between AP1 and AP2 is disconnected, the MESH interface MAC of AP2 is added to the MESH blacklist of AP1, and the blacklist time T1 of the MESH interface MAC of AP2 is refreshed to be 5s, so link 2 in fig. 2 is blocked. When the MAC of the AP exists in the MESH blacklist, the corresponding MESH connection can be blocked; and deleting the MAC, and automatically connecting the MESH connection of the corresponding AP. T1 of blacklist MAC minus 1 per second; after disconnecting the cable, when T1 is less than equal 0, the MAC blacklist is deleted and link 2 of fig. 2 is reconnected.
According to the control method of the wired and wireless hybrid networking provided by the embodiment of the application, if a current access point receives a first multicast message frame sent by a first access point through a wired network interface and the first access point is determined to be a direct connection neighbor of the current access point, a first wireless link between the current access point and the first access point is disconnected; and after the first set time length, the connection of the first wireless link is reestablished. When the loop is detected during the wired and wireless hybrid networking, the wireless link in the loop is controlled to be reestablished after the wireless link is disconnected for the first set time, so that the normal service of an access point is prevented from being influenced, and the efficiency of the hybrid networking can be improved.
In an alternative embodiment, the first multicast message frame includes a physical address of a wireless network interface of the first access point; in the step S502, after the first set time period, the connection of the first radio link is reestablished, as shown in fig. 6, the following steps are performed:
s601, according to a first set duration, setting a keep-alive time corresponding to a physical address of a wireless network interface of a first access point in a connection prohibition address list of the current access point.
Optionally, the first set time period is 5 s.
Illustratively, the first set time period is 5 s. In the connection prohibition address list of the current access point AP1, the keep-alive time corresponding to the physical address MAC02 of the wireless network interface of the first access point AP2 is set to 5 s.
In some embodiments, setting, according to a first set duration, a keep-alive time corresponding to a physical address of a wireless network interface of a first access point in a connection prohibition address list of a current access point includes:
if the connection prohibition address list of the current access point contains the physical address of the wireless network interface of the first access point, the keep-alive time of the physical address of the wireless network interface of the first access point is set as a first set duration; alternatively, the first and second liquid crystal display panels may be,
if the connection prohibition address list of the current access point does not contain the physical address of the wireless network interface of the first access point, the physical address of the wireless network interface of the first access point is added into the connection prohibition address list of the current access point, and the keep-alive time of the physical address of the wireless network interface of the first access point is set as a first set time length.
And S602, reducing the keep-alive time corresponding to the physical address of the wireless network interface of the first access point by a set value every second set time.
Alternatively, the second set time period is 1s, and the set value is 1 s.
Illustratively, every 1s, the keep-alive time corresponding to the physical address MAC02 of the wireless network interface of the first access point AP2 is reduced by 1 s.
S603, until the keep-alive time corresponding to the physical address of the wireless network interface of the first access point is less than or equal to zero, deleting the physical address of the wireless network interface of the first access point from the connection forbidding address list, and reestablishing the connection of the first wireless link.
Specifically, every second set time interval, monitoring whether the keep-alive time corresponding to the physical address of the wireless network interface of the first access point is less than or equal to zero. And if the keep-alive time corresponding to the physical address of the wireless network interface of the first access point is monitored to be less than or equal to zero, deleting the physical address of the wireless network interface of the first access point from the connection forbidding address list, and reestablishing the connection of the first wireless link.
