Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the embodiments of the present application and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1, an embodiment of the present application provides a network control method. The network control method comprises the following steps:
01: detecting a protocol supported by a switch in the Ethernet ring network;
02: determining a target protocol of each Ethernet ring according to protocols supported by all switches in each Ethernet ring; and
03: The protocol of the switch of each Ethernet ring is switched according to the target protocol of each Ethernet ring.
Referring to fig. 2, an embodiment of the present application provides a network control device 10. The network control device 10 comprises a first detection module 11, a first determination module 12 and a switching module 13. The network control method of the embodiment of the present application is applicable to the network control apparatus 10. The first detection module 11, the first determination module 12 and the switching module 13 are used for executing the steps 01, 02 and 03 respectively. That is, the first detection module 11 is configured to detect a protocol supported by a switch in the ethernet ring. The first determining module 12 is configured to detect a protocol supported by a switch in the ethernet ring; determining a target protocol of each Ethernet ring according to protocols supported by all switches in each Ethernet ring; and switching the protocol of the switch of each Ethernet ring according to the target protocol of each Ethernet ring.
Referring to fig. 3, an embodiment of the present application provides a vehicle 100. The network control method of the embodiment of the application is applicable to the vehicle 100. The vehicle 100 includes a processor 30. The processor 30 is configured to perform steps 01, 02 and 03. That is, the processor 30 is configured to detect a protocol supported by a switch in the ethernet ring; determining a target protocol of each Ethernet ring according to protocols supported by all switches in each Ethernet ring; and switching the protocol of the switch of each Ethernet ring according to the target protocol of each Ethernet ring.
Specifically, processor 30 may first detect the protocol supported by the switches in the Ethernet ring. The Ethernet ring network may include a plurality of switches, and protocols supported by each switch in the plurality of switches may be consistent or inconsistent.
For example, the switch support protocol may be a Time sensitive network (Time-SENSITIVE NETWORK, TSN) protocol, such as the TSN-CB protocol, and the switch support protocol may also be an ethernet multi-ring protection (ETHERNET RING Protection Switching, ERPS) protocol. Among the plurality of switches, one part may support the TSN-CB protocol and the other part may support the ERPS protocol. Processor 30 may detect to obtain the protocols supported by each switch in the ethernet ring.
In addition, the ethernet ring may be composed of a plurality of sub-rings, i.e. the ethernet ring is composed of a plurality of sub-ethernet rings. And each sub-ethernet ring is also an ethernet ring.
For example, referring to fig. 4, ethernet ring ABC is composed of sub ethernet ring a, sub ethernet ring B and sub ethernet ring C, and ethernet ring ABC includes switch 1, switch 2, switch 3, switch 4 and switch 5. The sub Ethernet ring A comprises a switch 1, a switch 2 and a switch 3, the sub Ethernet ring B comprises a switch 1, a switch 3 and a switch 4, and the sub Ethernet ring C comprises a switch 1, a switch 4 and a switch 5.
When the processor 30 detects the protocol supported by the switch 1 to the switch 5 in the ethernet ring ABC, the protocol supported by the switch 1 to the switch 5 may be obtained by detecting the protocols supported by the switches in the sub ethernet ring a, the sub ethernet ring B and the sub ethernet ring C.
Next, processor 30 may determine the target protocol for each ethernet ring based on the protocols supported by all switches in each ethernet ring. It will be appreciated that each ethernet ring, namely sub-ethernet ring a, ethernet ring B and ethernet ring C in ethernet ring ABC described above. The target protocol is a protocol supported by each switch in the Ethernet ring network when each Ethernet ring network can ensure normal data transmission.
With continued reference to fig. 4, when the processor 30 detects a protocol supported by a switch in the ethernet ring ABC, then all the protocols supported by the switches in each sub-ethernet ring may be detected.
Taking the sub ethernet ring a as an example for illustration, after the processor 30 obtains the protocols supported by the switch 1, the switch 2 and the switch 3 in the sub ethernet ring a, the processor 30 can determine the target protocol of the sub ethernet ring a. It should be noted that when the switch supports the TSN-CB protocol, the switch supports the ERPS protocol at the same time, and when the switch supports the ERPS protocol, the switch does not necessarily support the TSN-CB protocol.
Therefore, after the processor 30 determines the protocols supported by the switches 1,2 and 3 in the sub-ethernet ring a, to ensure that the data can be normally transmitted in the sub-ethernet ring a, when any one of the switches 1,2 and 3 does not support the TSN-CB protocol, that is, only the ERPS protocol is supported, the processor 30 determines that the target protocol is the ERPS protocol. And when the TSN-CB protocol is supported at each of switch 1, switch 2 and switch 3, processor 30 may determine that the target protocol may be the ERPS protocol or the TSN-CB protocol.
Finally, the processor 30 may switch the protocol of the switch of each ethernet ring according to the target protocol of each ethernet ring. For example, if the target protocol of the sub ethernet ring a is the ERPS protocol, the protocols of the switch 1, the switch 2 and the switch 3 are the ERPS protocols. For another example, if the target protocol of the sub ethernet ring B is the TSN-CB protocol, the protocols of the switch 1, the switch 3 and the switch 4 are TSN-CB protocols. Also for example, if the target protocol of the sub ethernet ring C is the ERPS protocol or the TSN-CB protocol, the protocols of the switch 1, the switch 4 and the switch 5 are the TSN-CB protocol or the EPRS protocol.
In the network control method, the network control device 10 and the vehicle 100 according to the embodiments of the present application, after detecting the protocol supported by the switch in the ethernet ring, the target protocol of each ethernet ring may be determined according to the protocols supported by all the switches in each ethernet ring, so as to switch the protocol of the switch in each ethernet ring according to the target protocol of each ethernet ring. Thus, for the multi-ring Ethernet, in the data transmission process, each Ethernet ring in the multi-ring Ethernet can use the same protocol or different protocols, so that the Ethernet ring can be compatible with switches of different protocols.
Referring to fig. 2,3 and 5, in some embodiments, step 01: detecting a protocol supported by a switch in an ethernet ring, comprising the steps of:
011: initializing an Ethernet ring network to initialize a controller and a switch in the Ethernet ring network;
012: sending a detection signal to each switch in the Ethernet ring network through the target controller so as to acquire a feedback signal of the switch; and
013: The protocol supported by each switch is determined based on the feedback signals.
In some embodiments, the first detection module 11 is configured to perform steps 011, 012, and 013. That is, the first detection module 11 is configured to initialize the ethernet ring to initialize the controller and the switch in the ethernet ring. Sending a detection signal to each switch in the Ethernet ring network through the target controller so as to acquire a feedback signal of the switch; and determining the protocol supported by each switch according to the feedback signals.
In certain embodiments, processor 30 is configured to perform steps 011, 012, and 013. That is, the processor 30 initializes the ethernet ring to initialize the controller and the switch in the ethernet ring; sending a detection signal to each switch in the Ethernet ring network through the target controller so as to acquire a feedback signal of the switch; and determining the protocol supported by each switch according to the feedback signals.
Specifically, the ethernet ring is provided with a controller corresponding to each switch one by one, and when the processor 30 detects a protocol supported by the switches in the ethernet ring, the processor 30 may initialize the ethernet ring first to initialize the controllers and the switches in the ethernet ring.
When initializing the controller and the switch, the controller and the switch may send their own initialization status to the processor 30, and the processor 30 may determine whether the controller and the switch are initialized. If the controller and the switch are not initialized, the processor 30 determines that the controller and the switch are damaged.
When the controller and the switches are initialized, the processor 30 may send a detection signal to each switch in the ethernet ring through the target controller to obtain a feedback signal of the switch. The target controllers are the controllers with the largest number of connection controllers in the Ethernet ring. The feedback signal may indicate a protocol supported by the switch.
For example, referring to fig. 4, it can be seen that, in the ethernet ring network ABC, the controller 1 corresponding to the switch 1 is connected to the controller 2, the controller 3, the controller 4 and the controller 5, that is, the number of connected controllers is the largest, that is, the controller 1 is the target controller.
Therefore, when the processor 30 sends the detection signal through the target controller, the search signal can be sent to each controller in the ethernet ring through the target controller, so as to obtain the feedback signal of the switch corresponding to each controller.
Finally, the processor 30 may determine the protocol supported by each switch based on the switch's feedback signals. For example, reference numeral 1 is given to TSN-CB protocol and reference numeral 2 is given to ERPS protocol. When the controller 1 sends a detection signal to the controller 2 to acquire that the feedback signal of the switch 2 corresponding to the controller 2 is 1, the protocol supported by the switch is determined to be TSN-CN protocol.
Referring to fig. 2, 3 and 6, in some embodiments, step 012: sending a detection signal to each switch in the ethernet ring network through the target controller to obtain a feedback signal of the switch, comprising the steps of:
0121: sending detection signals to a switch corresponding to the main controller and each sub-controller through the main controller so as to acquire feedback signals of the switch corresponding to the main controller; and
0122: And forwarding the detection signal to the switch in the Ethernet ring corresponding to each sub-controller through each sub-controller so as to acquire a feedback signal of the switch in each Ethernet ring.
In certain embodiments, the first detection module 11 is configured to perform steps 0121 and 0122. That is, the first detection module 11 is configured to send, by using the main controller, a detection signal to the switch corresponding to the main controller and each sub-controller, so as to obtain a feedback signal of the switch corresponding to the main controller; and forwarding the detection signal to the switch in the Ethernet ring corresponding to each sub-controller through each sub-controller so as to acquire a feedback signal of the switch in each Ethernet ring.
In certain embodiments, processor 30 is configured to perform steps 0121 and 0122. That is, the processor 30 is configured to send, by the main controller, a detection signal to the switch corresponding to the main controller and each sub-controller, so as to obtain a feedback signal of the switch corresponding to the main controller; and forwarding the detection signal to the switch in the Ethernet ring corresponding to each sub-controller through each sub-controller so as to acquire a feedback signal of the switch in each Ethernet ring.
Specifically, the target controller may include a main controller and a sub controller. The main controller is the controller with the largest number of connected controllers in all Ethernet rings. The sub-controllers are the controllers with the largest number of connection controllers in each Ethernet ring.
Taking fig. 4 as an example for illustration, all ethernet rings form ethernet ring ABC, and the master controller is controller 1. The Ethernet ring network ABC consists of a sub Ethernet ring network A, a sub Ethernet ring network B and a sub Ethernet ring network C.
Furthermore, the two sub-Ethernet ring networks can also form an Ethernet ring network. For example, the sub ethernet ring a and the sub ethernet ring B form an ethernet ring AB, and the sub ethernet ring B and the sub ethernet ring C form an ethernet ring BC.
Then, for the ethernet ring AB, the most connected controllers are the controller 3, except the main controller 1, i.e. the sub-controllers of the ethernet ring AB are the controllers 3.
For the sub-ethernet ring a, the controller 1 and the controller 3 are respectively a main controller of the ethernet ring ABC and a sub-controller of the ethernet ring AB, so that the controller 2 is a sub-controller of the sub-ethernet ring a.
When the processor 30 sends the detection signal to each switch in the ethernet ring through the target controller to obtain the feedback signal of the switch, the processor 30 may first send the detection signal to the switch corresponding to the main controller and each sub-controller through the main controller.
Thus, the processor 30 can first acquire the feedback signal of the switch corresponding to the master controller to determine the protocol supported by the switch corresponding to the master controller. For example, the processor 30 transmits a detection signal to the switch 1 through the controller 1 to acquire a feedback signal of the switch 1, thereby determining a protocol supported by the switch 1.
The processor 30 may further forward the detection signal to the switch in the ethernet ring corresponding to each sub-controller through each sub-controller, so as to obtain a feedback signal of the switch in each ethernet ring.
For example, the processor 30 sends the detection signal to the sub-controller (controller 3) of the ethernet ring AB through the main controller (controller 1), and the sub-controller may forward the detection signal to all switches (switch 1, switch 2, switch 3) in the ethernet ring AB, so as to obtain feedback signals of all switches in the ethernet ring AB. The feedback signals of all switches in the ethernet ring AB are forwarded to the main controller again through the sub-controllers, so as to be acquired by the processor 30.
Thus, when the processor 30 obtains feedback signals of all switches in the ethernet ring, the detection signals do not need to be sent to each switch in the ethernet ring one by one through the main controller, but are forwarded to the corresponding switch of each controller through the sub-controllers, so that when the number of switches is large, the time for the processor 30 to detect through the main controller is saved, the speed of switching the switch protocol is ensured, and the speed of data transmission is ensured.
Referring to fig. 2, 3 and 7, in some embodiments, step 02: according to the protocol supported by all switches of each Ethernet ring, determining the target protocol of each Ethernet ring, comprising the following steps:
021: under the condition that all protocols supported by switches of the Ethernet ring network are first preset protocols, determining that an Ethernet ring network target protocol is the first preset protocol or a second preset protocol; and
022: And under the condition that a second preset protocol exists in the protocols supported by all switches of the Ethernet ring, determining the target protocol of the Ethernet ring as the second preset protocol.
In certain embodiments, the first determination module 12 is configured to perform steps 021 and 022. The first determining module 12 is configured to determine that the ethernet network target protocol is a first preset protocol or a second preset protocol when all protocols supported by all switches of the ethernet network are first preset protocols; and under the condition that a second preset protocol exists in the protocols supported by all the switches of the Ethernet ring, determining the target protocol of the Ethernet ring as the second preset protocol.
In certain embodiments, processor 30 is configured to perform steps 021 and 022. That is, the processor 30 is configured to determine that the ethernet network target protocol is the first preset protocol or the second preset protocol when all the protocols supported by the switches of the ethernet network are the first preset protocol; and under the condition that a second preset protocol exists in the protocols supported by all the switches of the Ethernet ring, determining the target protocol of the Ethernet ring as the second preset protocol.
Specifically, after the processor 30 detects the protocols supported by all switches in the ethernet ring, the processor 30 may determine the target protocol of each ethernet ring according to the protocols supported by all switches in each ethernet ring.
More specifically, in the case that the processor 30 determines that all the protocols supported by the switches of the ethernet ring network are the first preset protocol, determining that the target protocol of the ethernet ring network is the first preset protocol or the second preset protocol; when the processor 30 determines that the second preset protocol exists in the protocols supported by all the switches in the ethernet network, the processor 30 may determine that the target protocol of the ethernet network is the second preset protocol. The first preset protocol is a TSN-CB protocol, and the second preset protocol is an EPRS protocol.
It will be appreciated that switches supporting the TSN-CB protocol also support the ERPS protocol, while switches supporting the ERPS protocol do not support the TSN-CB protocol.
Referring to fig. 4, using ethernet ring ABC as an example, processor 30 may determine the protocols supported by switch 1, switch 2, switch 3, switch 4, and switch 5. If the switches 1 to 5 all support the first preset protocol, that is, all support the TSN-CB protocol, the target protocol of the ethernet ring ABC is the TSN-CB protocol or the ERPS protocol.
If any one of the switches 1 to 5 supports the second preset protocol, that is, the ERPS protocol, then the target protocol of the ethernet ring ABC is the ERPS protocol.
In the ethernet ring a, after acquiring the protocols supported by the switch 1, the switch 2 and the switch 3, the processor 30 may determine the target protocol of the ethernet ring a by determining whether the switch 1, the switch 2 and the switch 3 all support the first preset protocol or whether any switch supports the second preset protocol.
Thus, the processor 30 can determine the target protocol of each ethernet ring based on the protocols supported by all switches in each ethernet ring.
Referring to fig. 2, 3 and 8, in some embodiments, step 02: according to the protocol supported by all switches of each Ethernet ring, determining the target protocol of each Ethernet ring, and further comprising the steps of:
023: under the condition that a second preset protocol exists in the protocols supported by the switches shared by the two adjacent Ethernet rings, determining the target protocols of the two adjacent Ethernet rings as the second preset protocol; and
024: And under the condition that the protocols supported by the switches shared by the two adjacent Ethernet rings are all first preset protocols, determining that the target protocols of the two adjacent Ethernet rings are the same or different.
In certain embodiments, the first determination module 12 is configured to perform steps 023 and 024. That is, the first determining module 12 is configured to determine that the target protocol of the two adjacent ethernet rings is the second preset protocol when the second preset protocol exists in the protocols supported by the switches shared by the two adjacent ethernet rings; and under the condition that the protocols supported by the switches shared by the two adjacent Ethernet rings are the first preset protocols, determining that the target protocols of the two adjacent Ethernet rings are the same or different.
In certain embodiments, processor 30 is configured to perform steps 023 and 024. That is, the processor 30 is configured to determine that the target protocol of the two adjacent ethernet rings is the second preset protocol when the second preset protocol exists in the protocols supported by the switches shared by the two adjacent ethernet rings; and under the condition that the protocols supported by the switches shared by the two adjacent Ethernet rings are the first preset protocols, determining that the target protocols of the two adjacent Ethernet rings are the same or different.
Specifically, when the processor 30 determines the target protocol of each ethernet ring, if the second preset protocol exists in the protocols supported by the switches shared by the two adjacent ethernet rings, the processor 30 may determine that the target protocol of the two adjacent ethernet rings is the second preset protocol.
For example, referring to fig. 4, switches shared by the ethernet ring a and the ethernet ring B are switch 1 and switch 3, and if there is a second preset protocol, that is, an ERPS protocol, in any one of the switches 1 and switch 3, then the target protocol of the ethernet ring a and the ethernet ring B is the ERPS protocol.
Furthermore, if the protocols supported by the switches shared by the two adjacent ethernet rings are the first preset protocol, that is, the TSN-CB protocol, the processor 30 may determine that the target protocols of the two adjacent ethernet rings may be the same or different.
For example, referring to fig. 4, switches shared by ethernet ring B and ethernet ring C are switch 1 and switch 4, and if both switch 1 and switch 4 support TSN-CB protocols, then the target protocols of ethernet ring B and ethernet ring C may be the same or different. The target protocols of the ethernet ring B and the ethernet ring C may be a first preset protocol or a second preset protocol; for another example, the target protocol of the ethernet ring B is a first preset protocol, the target protocol of the ethernet ring C is a second preset protocol, or the target protocol of the ethernet ring B is a second preset protocol, and the target protocol of the ethernet ring C is a first preset protocol.
In this way, in the ethernet ring network ABC, the target protocols of each ethernet ring network may be the same or different, that is, the ethernet ring network ABC can use the first preset protocol or the second preset protocol at the same time, so as to meet the requirement that the ethernet ring network can be compatible with switches of different protocols.
Referring to fig. 2, 3 and 9, after switching the protocol of the switch of the ethernet ring, the network control method according to the embodiment of the present application further includes the steps of:
04: detecting the protocol supported by the switch in each Ethernet ring after switching again;
05: determining a switching failure and re-entering a protocol for switching the switch of each Ethernet ring according to the target protocol of each Ethernet ring when the protocol supported by the switch of any Ethernet ring is not the target protocol corresponding to the Ethernet ring; and
06: And stopping protocol switching of the exchanger of each Ethernet ring network after the switching failure times reach the preset times.
In certain embodiments, the network control device 10 includes a second detection module 14, a second determination module 15, and a stop module 16. The second detection module 14 is used for executing step 04, the second determination module 15 is used for executing step 05, and the stop module 16 is used for executing step 06. That is, the second detection module 14 is configured to detect the protocol supported by the switch in each ethernet ring after the switching again. The second determining module 15 is configured to determine that the switching fails and reenters the step of switching the protocol of the switch of each ethernet ring according to the target protocol of each ethernet ring if there is a protocol supported by the switch of any ethernet ring that is not the target protocol corresponding to the ethernet ring. The stopping module 16 is configured to stop protocol switching of the switch of each ethernet ring after the number of switching failures reaches a preset number.
In certain embodiments, processor 30 is configured to perform step 05, step 06, and step 07. That is, the processor 30 is configured to detect again the protocol supported by the switch in each ethernet ring after the switching; determining a switching failure and re-entering a protocol for switching the switch of each Ethernet ring according to the target protocol of each Ethernet ring when the protocol supported by the switch of any Ethernet ring is not the target protocol corresponding to the Ethernet ring; and stopping protocol switching of the exchanger of each Ethernet ring network after the switching failure times reach the preset times.
Specifically, after the processor 30 switches the protocol of the switch of each ethernet ring according to the target protocol of each ethernet ring, to ensure that the protocol of the switch is switched successfully, the processor 30 needs to detect the protocol supported by the switch of each ethernet ring after the switching again.
If there is any protocol supported by the switches in the ethernet ring network that is not the target protocol corresponding to the ethernet ring network, the processor 30 determines that the protocol switching of the switches in the ethernet ring network fails, and reenters the step of switching the protocol of the switches in each ethernet ring network according to the target protocol of each ethernet ring network, so as to re-switch the protocol of the switches in each ethernet ring network.
When the number of switching failures reaches the preset number, the processor 30 stops switching the protocol of the switch of each ethernet ring, i.e. determines that the switch has a failure. The preset times can be 3 times, 5 times, 10 times and the like, and are manually set experience values.
Referring to fig. 4 and 10, the network control method according to the embodiment of the application is as follows:
1. firstly, the controller with the largest number of connected controllers, namely the controller 1 is used as a main controller, and the sub-controller of each Ethernet ring network, such as the sub-controller of the Ethernet ring network AB is used as a controller 3, the sub-controller of the Ethernet ring network A is used as a controller 2, and the like, so that the main controller is prevented from detecting each controller and each switch one by one, and the detection time is saved.
2. During S1 period, for the initialization phase, the processor 30 initializes the controller and the switch.
3. In the S2 period, the processor 30 acquires an initialization signal of the switch of each ethernet ring, thereby determining whether or not damage occurs to each controller and switch according to the initialization signal.
4. In the S3 period, the processor 30 transmits a detection signal to the sub-controller of each ethernet ring network through the main controller (controller), and synchronously transmits the detection signal to the switch corresponding to the main controller.
5. In the S4 period, the processor 30 may receive the feedback signals of the switches corresponding to the main controller and the feedback signals of all the sub-controllers to determine the protocol supported by each switch, thereby determining the target protocol of each ethernet ring.
6. In the S5 period, the processor 30 may switch the protocol of each switch through the target protocol of each ethernet ring, and after the protocol switching is completed, send a detection signal to the sub-controller of each ethernet ring again to detect the protocol of each switch of each ethernet ring, and determine whether the protocol of each switch of each ethernet ring is successfully switched according to the state feedback of each switch of each ethernet ring, and when the switching fails, switch again until the switching times reach the preset times, and stop switching the protocol of each switch of each ethernet ring to determine that the switch has a fault.
Referring to fig. 2, fig. 3, and fig. 11, when the ethernet ring network performs communication according to a first preset protocol, the network control method according to the embodiment of the present application further includes the steps of:
07: the communication is performed simultaneously through a plurality of different communication paths connecting any two switches, the communication paths comprising links of the ethernet ring network and/or the switches.
In certain embodiments, the network control device 10 comprises a communication module 17, the communication module 17 being configured to perform step 07. That is, the communication module 17 is configured to simultaneously perform communication through a plurality of different communication paths connecting any two switches, where the communication paths include links and/or switches of the ethernet ring.
In certain embodiments, processor 30 is configured to perform step 07. That is, the processor 30 is configured to communicate simultaneously over a plurality of different communication paths connecting any two switches, the communication paths including links and/or switches of the Ethernet ring network.
Specifically, when the ethernet ring communicates in the first preset protocol, the processor 30 may communicate simultaneously through a plurality of different communication paths connecting the two switches. The communication path may include a link with an ethernet ring, a switch with an ethernet ring, and a link and a switch with an ethernet ring.
For example, referring to fig. 12, when the ethernet ring X communicates with the first preset protocol, if the data of the controller 2 needs to be sent to the controller 1, the processor 30 may send the data to the switch 1 through the link ① between the switch 2 and the switch 1, or may send the data to the switch 3 through the link ② between the switch 2 and the switch 3 first through the switch 2, and then send the data to the switch 1 through the link ③ between the switch 3 and the switch 1.
Therefore, when the Ethernet ring network communicates through the first preset protocol, a plurality of communication paths for transmitting data can be ensured, and redundancy of the data transmission paths is ensured, so that normal communication can be ensured.
Referring to fig. 2, fig. 3, and fig. 13, when the ethernet ring network performs communication according to a second preset protocol, the network control method according to the embodiment of the present application further includes the steps of:
08: blocking a preset link of each Ethernet ring network so that the Ethernet ring network cannot form a ring network; and
09: In case of a link failure of the ethernet ring network, the blocked link is opened.
In certain embodiments, the communication module 17 is configured to perform step 08 and step 09. That is, the communication module 17 is configured to block a preset link of each ethernet ring, so that the ethernet ring cannot form a ring network; and opening the blocked link under the condition that the link fault exists in the Ethernet ring network.
In certain embodiments, processor 30 is configured to perform step 08 and step 09. That is, the processor 30 is configured to block a preset link of each ethernet ring, so that the ethernet ring cannot form a ring network; and opening the blocked link under the condition that the link fault exists in the Ethernet ring network.
Specifically, when the ethernet ring networks communicate through the second preset protocol, since the ethernet ring networks include a plurality of sub ethernet ring networks, in order to prevent a network storm formed by the plurality of sub ethernet ring networks due to broadcast messages, each ethernet ring network needs to be destroyed, that is, a link is blocked, so as to ensure normal communication of data.
Therefore, when the ethernet ring networks communicate through the second preset protocol, the processor 30 also blocks the preset link of each ethernet ring network, so that the ethernet ring networks cannot form a ring network, that is, the generation of a network storm is avoided. The preset link may be a communication link set manually in advance.
Then, when there is a link failure in the ethernet ring, the processor 30 opens the blocked link to ensure normal communication of data.
More specifically, referring to fig. 12, an ethernet ring Z is taken as an example, and the switch 5 of the controller 5 may directly transmit data to the corresponding switch of the controller 1, or may transmit data to the controller 1 through the switch 4 of the controller 4. When the ethernet ring Z communicates through the second preset protocol, the processor 30 blocks the link ④ between the controllers 5, so that the ethernet ring Z cannot form a ring network, thereby avoiding occurrence of a network storm. It will be appreciated that when the ethernet ring X and the ethernet ring Y communicate through the second preset protocol, the processor 30 blocks the link ① and the link ⑤, so that the ethernet ring X and the ethernet ring Y cannot form a ring network, thereby avoiding occurrence of a network storm. The blocked link is a port of the switch corresponding to the blocked link, for example, the blocked link 4 is a port1 of the switch 5 and a port 2 of the switch 1 are closed.
Next, when the controller 4 transmits data through the link ⑦, and when the link ⑦ fails, the processor 30 opens the blocked link ④, i.e. the port between the switch 5 and the switch 1, to ensure that the data can be normally transmitted, and when the link ⑥ fails, i.e. the link is blocked, the ethernet ring Z cannot form a network storm.
In this way, the processor 30 can ensure that the ethernet ring network will not form a network storm when communicating through the second preset protocol by blocking the link, and can also ensure the normal communication of the data.
