[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] SRB network generally includes multiple node devices. It is meaningful to determine whether it is a ring topology or a linear topology only when the number of node devices is more than 3. For example, when there are only two node devices, it can only be a linear topology. For example, when the number of node devices is 3, the MAC address of each node device is 00:00:00:00:01:01, 00:00:00:00:01:02 and 00:00:00:00:01:03. Each node device will store a corresponding MAC value. One MAC value corresponds to the MAC address of a node device connected to it. When the three node devices are in a linear topology, their connection method is as follows: Figure 1 As shown, when the three node devices are ring topology devices, their connection method is as follows Figure 2 Based on the above premise, the present application provides the following specific embodiments to determine the specific topology of the SRB network.

[0051] Figure 3 This is a flowchart of a topology structure scanning method according to an embodiment of the present application.

[0052] like Figure 3 As shown, the topology structure scanning method provided by this application is applied to electronic devices, which can be understood as computers, servers, embedded devices, mobile devices or cloud platforms with data computing and information processing capabilities. The topology structure scanning method of this application is specifically described as follows:

[0053] S1. Obtain the MAC address and stored MAC value of each node device.

[0054] By sending broadcast messages, the MAC address of each node device is collected, and the MAC value stored by each node device is obtained. The MAC value here is the MAC address of the node device to which the node device is connected. For example, if node device 1 is connected to node device 2 and node device 3, the MAC value stored in it is the MAC address of node device 3 and node device 3.

[0055] S2. Determine the topology of the SRB network by traversing each node device.

[0056] Specifically, by traversing all node devices in turn, it is determined whether there is an end node based on the MAC address of each power-saving device and its stored MAC value. If it exists, it indicates that the SRB network is a linear topology structure, otherwise it indicates that the SRB network is a ring topology structure. The specific process is as follows Figure 4 As shown:

[0057] S201: Determine whether there is an end node among all node devices.

[0058] All node devices are judged in turn using preset rules to determine whether there is an end node. The so-called end node refers to a node device with only one port connected to another node device and the other port is left unconnected.

[0059] S202: If there are end nodes, it is determined to be a linear topology structure.

[0060] That is, if the above determination shows that there is an end node among all the node devices, it indicates that the topology of the SRB network is a linear topology. Generally speaking, there should be two end nodes, thus forming a linear topology with end nodes as both ends.

[0061] S202: If no end node exists, determine that the topology is a ring structure.

[0062] That is, if, after the above determination, no end node exists in all the node devices, it indicates that the topology of the SRB network is a ring topology.

[0063] In this embodiment, the determination of whether the end node exists is realized based on the following method: Figure 5 shown.

[0064] S2011. Determine the current node device.

[0065] A node device is selected from all node devices as the current node device. The current node device is any one of all node devices, which can be at the end or in the middle, that is, both ports of the current node device are connected to a node device.

[0066] S2012. Determine whether the current node device only stores one MAC value.

[0067] That is, the MAC value of each node device is determined to determine whether it has one MAC value or two MAC values. If it has one MAC value, the subsequent step S2013 is executed; if it has two MAC values, the subsequent step S2014 is executed.

[0068] S2013. Determine that the current node device is an end node.

[0069] That is, if it is found that the current node device only stores one MAC value, then the node device is determined to be an end node. In this case, the current process ends.

[0070] S2014: Determine whether the other node device is the original current node device.

[0071] If the current node device stores two MAC values, and each MAC value corresponds to a MAC address of another node device connected to the current node, it is determined whether the other node device is the original current node device.

[0072] S2015. Determine another node device as the current node device.

[0073] If it is not the initially selected current node device, the other node device is determined as the current node device, and the process returns to step S2012, ie, the step of determining whether the current node device stores one MAC value or two MAC values.

[0074] S2016: Determine that no end node exists.

[0075] If the other node device is the initially selected current node device, it is determined that no end node exists, and this process ends.

[0076] As can be seen from the above technical solution, this embodiment provides a method for scanning the topology of an SRB network. The method is applied to an electronic device and is used to scan the topology of an SRB network, which includes multiple node devices. The topology scanning method obtains the MAC address and stored MAC value of each node device; traverses each node device, and determines the topology of the SRB network based on the number of MAC values of the node device and the correspondence between the MAC value and the MAC address, thereby determining whether the topology of the SRB network is a linear topology or a ring topology.

[0081] Figure 6 This is a block diagram of a topology scanning device according to an embodiment of the present application.

[0082] like Figure 6As shown, the topology structure scanning device provided by the present application is applied to an electronic device, which can be understood as a computer, server, embedded device, mobile device or cloud platform with data computing and information processing capabilities. The topology structure scanning device of the present application specifically includes a parameter acquisition module 10 and a scanning execution module 20.

[0083] The parameter acquisition module is used to obtain the MAC address and stored MAC value of each node device.

[0084] By sending broadcast messages, the MAC address of each node device is collected, and the MAC value stored by each node device is obtained. The MAC value here is the MAC address of the node device to which the node device is connected. For example, if node device 1 is connected to node device 2 and node device 3, the MAC value stored in it is the MAC address of node device 3 and node device 3.

[0085] The scanning execution module is used to determine the topology of the SRB network by traversing each node device.

[0086] Specifically, by traversing all node devices in sequence, it is determined whether an end node exists based on the MAC address of each power-saving device and its stored MAC value. If it exists, it indicates that the SRB network is a linear topology structure, otherwise it indicates that the SRB network is a ring topology structure. The module specifically includes an end node determination unit 21, a first determination unit 22, and a second determination unit 23, such as Figure 7 shown.

[0087] The end node determination unit is used to determine whether an end node exists in all node devices.

[0088] All node devices are judged in turn using preset rules to determine whether there is an end node. The so-called end node refers to a node device with only one port connected to another node device and the other port is left unconnected.

[0089] The first determining unit is configured to determine that the topology is a linear structure if an end node exists.

[0090] That is, if the above determination shows that there is an end node among all the node devices, it indicates that the topology of the SRB network is a linear topology. Generally speaking, there should be two end nodes, thus forming a linear topology with end nodes as both ends.

[0091] The second determining unit is configured to determine that the topology is a ring structure if no end node exists.

[0092] That is, if, after the above determination, no end node exists in all the node devices, it indicates that the topology of the SRB network is a ring topology.

[0093] In this embodiment, the end node determination unit determines whether the end node exists based on the above steps S2011 to S2016, which will not be repeated here.

[0094] As can be seen from the above technical solution, this embodiment provides a topology scanning device for an SRB network. The device is applied to an electronic device and is used to scan the topology of an SRB network, which includes multiple node devices. The topology scanning device is used to obtain the MAC address and stored MAC value of each node device; traverse each node device, and determine the topology of the SRB network based on the number of MAC values of the node device and the correspondence between the MAC value and the MAC address, thereby determining whether the topology of the SRB network is a linear topology or a ring topology.
