Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

The dual-redundant communication method based on port routing management provided by the embodiment of the present application can be applied in the application environment as shown in Figure 1. Among them, the terminal 102 communicates with the server 104 through the network. The terminal 102 can be used as a sending node or a receiving node. The server 104 can be deployed on a switch or on a control system that controls a switch network composed of multiple switches. . The data storage system may store data that server 104 needs to process. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, etc. . Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented as an independent server or a server cluster composed of multiple servers.

In an exemplary embodiment, as shown in Figure 2, a dual-redundant communication method based on port routing management is provided. This method is applied to the server 104 in Figure 1. The current example is used for illustration, and the server 104 Deploy on the current switch, where the current switch exists in a switch cluster including multiple switches. The above method includes the following steps S202 to S208. in:

Step S202: Receive information to be transmitted.

The information to be transmitted is information from the sending node, which carries the destination address.

For example, the information to be transmitted may be an FC frame of a fiber channel. In Fiber Channel (FC), FC frame refers to the frame (Frame) in the Fiber Channel protocol. Fiber Channel is a high-performance, high-speed network technology mainly used for storage area networks and other applications that require high-performance data transmission. In Fiber Channel, data is divided into frames for transmission. Each frame contains control information, data, and parity fields for error detection. The Fiber Channel protocol defines the structure of frames and how data is transmitted. Further, the general structure of an FC frame includes frame header information, frame control information, data load and check fields.

Step S204: Check the connectivity between the current switch and the node corresponding to the destination address.

Among them, the node corresponding to the destination address is the data receiving node.

For example, when the current switch is in normal working condition and no fault occurs, the above information to be transmitted should be sent by the sending node and directly sent to the node corresponding to the target address via the current switch, that is, the data receiving node. The server 104 can The check result is obtained by checking whether the sending port connected to the node corresponding to the destination address is in normal working condition. Further, the server 104 can extract the frame header information of the FC frame to obtain the destination address, and then perform routing query according to the destination address to obtain the target node, and check whether the interface connecting the current switch and the target node is in working state to obtain connectivity. Condition.

Step S206: If the current switch is not connected to the node corresponding to the destination address, query the target switch connected to the node corresponding to the destination address.

For example, the server 104 can continuously monitor multiple switches and continue to periodically obtain port working status information from multiple switches, where the port working status information is used to characterize the working status of the communication ports between the switch and each node. When the current switch is not connected to the node corresponding to the destination address, the server 104 may query the target switch connected to the node corresponding to the destination address based on the switch port working status information obtained in history. In addition, the server 104 can also temporarily obtain the port working status information when the current switch is not connected to the node corresponding to the destination address, and then query the target switch connected to the node corresponding to the destination address.

Step S208: Send the information to be transmitted to the target switch to instruct the target switch to forward the information to be transmitted to the node corresponding to the destination address.

For example, the server 104 can send the information to be transmitted to the target switch. At this time, the target switch is still in normal working state. When the target switch receives the information to be transmitted sent by the current switch, it will also first treat the destination in the transmission information. Address is identified, and the information to be transmitted is sent to the node corresponding to the destination address according to the destination address.

In the above-mentioned dual-redundant communication method based on port routing management, the connection status of the current switch and the node corresponding to the destination address is checked by identifying and analyzing the destination address in the information to be transmitted, thereby determining whether the current communication link is normal. working status. When the current switch is not connected to the node corresponding to the destination address, alternative communication links can be obtained by querying the target switch connected to the node corresponding to the destination address, and then the information to be transmitted is sent to The target switch can instruct the target switch to forward the information to be transmitted to the node corresponding to the destination address. In the case of problems such as a failure of the current switch communication link, the information to be transmitted can be forwarded by the target switch by querying available links, and the information transmission can be successfully completed. Among them, the current switch and the target switch are both in normal working status, and there is no backup switch setting. Only when the current switch fails and the check result shows that it is not connected, the target switch that can forward the information to be transmitted will be found. , and then establish a new information forwarding link. Therefore, it only needs to be deployed in a network of multiple switches to complete redundant communication in a fault state. There is no need to set up redundant switches in advance. This can not only successfully complete information forwarding, but also reduce the cost of use and maintenance.

In an exemplary embodiment, as shown in Figure 3, step S206 includes steps S302 to step S306. in:

Step S302: Determine the target node according to the destination address.

The target node refers to the receiving node indicated by the destination address that receives the information to be transmitted. For example, the server 104 can call a preset mapping table and query the target node according to the destination address carried in the information to be transmitted.

Step S304: Obtain the connectivity status of multiple candidate switches and the target node through the status monitoring interface.

In a communication network including multiple switches, a status monitoring interface exists between the current switch and multiple candidate switches. The status monitoring interface is used to continuously monitor the connectivity status between the candidate switch and multiple candidate nodes. For example, the server 104 can learn whether any candidate switch can replace the current switch in forwarding information based on the information returned by the status monitoring interface that represents the connectivity status between the candidate switch and multiple candidate nodes.

Step S306: Select a target switch from multiple candidate switches according to the connectivity status.

For example, after obtaining the connectivity status of multiple candidate switches and multiple candidate nodes respectively, the server 104 can determine which candidate switch is connected to the target node, so that the appropriate candidate switch can be selected from the multiple candidate switches. The switch serves as the target switch, and then completes the forwarding of the information to be transmitted through the target switch.

In an exemplary embodiment, the current switch includes multiple alternative communication interfaces. Step S208 includes: arbitrarily selecting one of the multiple alternative communication interfaces as a redundant communication interface according to the target switch, where the redundant communication interface Connected to the target switch; sending the information to be transmitted to the target switch through the redundant communication interface to instruct the target switch to forward the information to be transmitted to the node corresponding to the destination address.

For example, when multiple switches are in normal working state at the same time, the server 104 can obtain the working status of each alternative communication interface of the target switch, and then use any alternative communication interface of the target switch that is not currently in working status as the The redundant communication interface is used to receive the information to be transmitted from the current switch and send the information to be transmitted to the target switch through the redundant communication interface, which instructs the target switch to forward the information to be transmitted to the node corresponding to the destination address.

In an exemplary embodiment, step S202 also includes determining whether the information to be transmitted comes from a redundant communication interface.

For example, when the information to be transmitted does not come from the redundant communication interface, it can be considered that the current switch receives the information to be transmitted from the sending node, and there is a possibility that the current switch cannot connect with the node corresponding to the destination address. Therefore, , it is necessary to judge whether the information to be transmitted needs to be forwarded to the target switch through the above steps; conversely, when the information to be transmitted does not come from the redundant communication interface, it can be considered that the current switch receives the information to be transmitted from other switches, because In the preamble step, the switch that sends the information to be transmitted has completed the above judgment process. The current switch only needs to send the information to be transmitted to the node corresponding to the destination address.

For example, after obtaining the judgment result, the server 104 can perform the step of checking the connectivity between the current switch and the node corresponding to the destination address when the information to be transmitted does not come from the redundant communication interface; In the case of other communication interfaces, routing query is performed based on the destination address to obtain the target node; the information to be transmitted is sent to the target node.

In another embodiment, the server 104 is deployed on each switch in the switch network, and the switch network includes multiple switches, and there are redundant communication interfaces and status monitoring interfaces between each two switches, where the redundant A communication interface is any one of multiple alternative communication interfaces on the switch.

When a switch receives the information to be transmitted from the sending node of the terminal 102, the server 104 of the current switch parses the destination address in the information to be transmitted, and determines whether the interface on the current switch is used to connect to the node corresponding to the destination address. In the normal working state, when the interface is working normally, the server 104 can directly send the information to be transmitted to the destination address through the waiting interface; if the interface is not in the normal working state, the server 104 obtains the information in the network through the status monitoring interface. The connectivity between other candidate switches and the node corresponding to the destination address is determined, thereby selecting a target switch that meets the requirements, and selecting an alternative communication interface that is not working on the target switch at the current moment as a redundant communication interface, so that the information to be transmitted is passed through The redundant communication interface is sent to the target switch.

When the target switch receives the information to be transmitted from the redundant communication interface, it will identify and parse the destination address in the information to be transmitted, thereby obtaining the target node corresponding to the information to be transmitted, and send the information to be transmitted to the target node. Complete the smooth sending of the information to be transmitted.

Unless explicitly stated in this article, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders.
