[0063] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0064] The embodiment of the present application provides a dynamic update method based on the connection status of the FC switching network terminal. The execution subject of the dynamic update method based on the connection status of the FC switching network terminal includes but is not limited to at least one of the electronic devices such as the server and the terminal that can be configured to execute the method provided by the embodiment of the present application. In other words, the dynamic update method based on the connection status of the FC switching network terminal can be executed by software or hardware installed on the terminal device or the server device, and the software can be a blockchain platform. The server includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc.

[0065] Reference Figure 1 FIG. 1 is a flow chart of a method for dynamically updating a terminal connection state of an FC switching network provided by an embodiment of the present invention. In this embodiment, the method for dynamically updating a terminal connection state of an FC switching network includes:

[0066] S1. Receive a login request from a terminal, send the login request to a pre-built switch, and use the switch to allocate a terminal address to the terminal.

[0067] It can be explained that the login request (Login, abbreviated as LOGI) refers to the communication protocol used when the terminal accesses the FC (Fiber Channel) switching network. The FC switching network is constructed using the FC protocol. The FC protocol is a high-speed serial communication protocol with the characteristics of high bandwidth, high reliability, low latency, flexible topology and openness, and is mainly used in avionics communication systems. In different FC protocols, the interaction mode between terminals is also different. For example: in FC-AE-1553, the terminals are divided into network controllers (NC) and network terminals (NT), and the interaction mode between the two is command response; in FC-AE-ASM, each terminal is an equal relationship.

[0068] It should be explained that since different FC protocols differ only in the FC-4 layer (upper layer protocol mapping layer, referred to as ULP mapping layer), a FC switching network fault monitoring and terminal connection information dynamic maintenance and update method independent of FC-4 can be proposed, which is applicable to all FC protocols.

[0069] Furthermore, the FC switching network has a variety of topological structures, among which the most common is a switching network, such as Figure 1 As shown, there are several switches interconnected in the FC switching network, each switch can be connected to several terminals, and the communication data between the terminals is forwarded through the switch.

[0070] In the embodiment of the present invention, sending the login request to a pre-built switch and using the switch to allocate a terminal address to the terminal includes:

[0071] According to the login request, obtaining a login protocol of the terminal;

[0072] generating a terminal address of the terminal in the switch according to a login protocol of the terminal;

[0073] Filling the terminal address into a pre-constructed initial login response frame to obtain a target login response frame;

[0074] The target login response frame is transmitted back to the terminal to complete the allocation of the terminal address.

[0075] It can be understood that the login protocol (Fabric Login, referred to as FLOGI) refers to a login protocol for establishing a connection between a terminal and a switch.

[0076] It should be understood that after receiving the login protocol, the switch will allocate an address to the terminal and fill it in the initial login response frame to obtain the target login response frame. The target login response frame (abbreviated as FLOGI LS_ACC) refers to the LS_ACC frame that the switch replies when receiving the login protocol sent by the terminal. The initial login response frame refers to the response frame to be filled in which the terminal address is not filled.

[0077] It can be explained that the terminal logging into the FC switching network is an explicit login, and the frames involved in login and logout are all ELS type frames. The definition of each field can be found in 4.2.7Login (FLOGI / PLOGI) and 4.2.8Logout (LOGO) in FC-LS-2.

[0078] S2. Obtain the name of the terminal and the identifier of the switch, and construct terminal information according to the terminal address, the name of the terminal and the identifier of the switch.

[0079] It can be explained that the terminal information includes the name of the terminal, the terminal address and the identifier of the switch connected to the terminal, and other information can be added according to actual needs.

[0080] S3. Store the terminal information in the terminal login information table of the switch to obtain a local login update terminal information table.

[0081] It should be explained that the terminal login information table refers to a collection of terminal information that is connected to the FC switching network and can communicate normally. The local login update terminal information table refers to storing the terminal information in the terminal login information table of the switch to update the original terminal login information table in the switch, thereby obtaining an information table.

[0082] Furthermore, the switch can be used to monitor the connection status of the physical link between the terminal and the switch. This process can be achieved through the FC-2 layer link fault monitoring function. If the physical layer completes word synchronization and the link layer completes primitive synchronization, it means that the physical link connection is normal, otherwise it means that the physical link is disconnected. When the physical link is disconnected, the corresponding terminal information in the terminal login information table needs to be deleted. If the physical link changes from disconnected to connected, no operation is performed, and the terminal waits for re-initiating explicit login.

[0083] S4. Determine whether the switch is a preset master switch.

[0084] It should be understood that the switches can be divided into two types: a main switch and a secondary switch. The main switch is responsible for maintaining the terminal access status of the entire network, and the secondary switch is responsible for maintaining the access status of the terminals connected to itself.

[0085] For details, see Figure 4 As shown, the step of determining whether the switch is a preset master switch includes:

[0086] S41, classifying switches according to a preset switch identification set to obtain a switch identification-category correspondence table;

[0087] S42, using the identifier of the switch, querying the switch category corresponding to the switch in the switch identifier-category correspondence table;

[0088] S43: Determine whether the switch is the master switch according to the switch type.

[0089] It can be explained that there can be one master switch in the FC switching network, and the other switches are all slave switches. Since the identifier of the switch is a unique identifier of the switch, the identifier of the switch can be used to distinguish whether the switch is a master switch or a slave switch.

[0090] If the switch is the main switch, S5 is executed to not forward the terminal information in the local login update terminal information table.

[0091] It can be understood that when the switch is the main switch, it means that the local login updated terminal information table in the switch can record the terminal information of all terminals in the entire network. At this time, the terminal information is stored in the terminal login information table in the main switch, which means that the maintenance of the terminal access status of the entire network has been achieved.

[0092] Furthermore, the main switch needs to maintain terminal information of terminals connected to itself as well as terminal information of terminals in the entire network.

[0093] If the switch is not the main switch, S6 is executed to send the terminal information in the local login update terminal information table to the terminal login information table of the main switch to obtain the whole network login update terminal information table.

[0094] It can be explained that the terminal information table updated by logging into the entire network refers to an information table that records the terminal information of all terminals in the FC switching network in real time.

[0095] In the embodiment of the present invention, the sending of the terminal information in the local login update terminal information table to the terminal login information table of the main switch to obtain the whole network login update terminal information table includes:

[0096] Construct an initial universal frame according to the pre-constructed FC universal frame structure and FC network standards;

[0097] Changing the frame type of the initial universal frame to obtain an initial login synchronization frame;

[0098] Fill the terminal information into the initial login synchronization frame to obtain a target login synchronization frame;

[0099] The target login synchronization frame is sent to the terminal login information table of the main switch to obtain the whole network login update terminal information table.

[0100] In detail, the FC general frame structure can be found in Figure 2 As shown. The initial universal frame refers to a universal frame that can be generated to achieve different functions by setting the frame type. For example: when the byte of the frame type (LS_Command Code) is 0xA7, it indicates the network node link state request protocol (Link State Request, referred to as LS_REQ); when the byte of the frame type (LS_Command Code) is 0xA8, it indicates the network node link state response protocol (Link State Acknowledge, referred to as LS_ACK).

[0101] Furthermore, the initial login synchronization frame refers to a frame to be completed that has a set frame type but has not yet filled with the terminal information. The target login synchronization frame (Link State Update, LSU for short) refers to a data frame used for link state synchronization between switches.

[0102] In the embodiment of the present invention, the step of sending the target login synchronization frame to the terminal login information table of the main switch to obtain the whole network login update terminal information table includes:

[0103] Sending the target login synchronization frame to the cascade port of the main switch through the cascade port of the switch;

[0104] Determining whether the cascade port of the main switch receives the target login synchronization frame for the first time;

[0105] If the cascade port of the main switch does not receive the target login synchronization frame for the first time, the target synchronization frame is discarded;

[0106] If the cascade port of the main switch receives the target login synchronization frame for the first time, the terminal login information table of the main switch is updated using the target login synchronization frame to obtain the whole network login updated terminal information table.

[0107] It can be explained that the terminal information is encapsulated through the target login synchronization frame, and then the target login synchronization frame is sent to the cascade port of the main switch through the interactive machine and the cascade ports of other sub-switches in the FC switching network, so that the main switch obtains the terminal information of the switch and the corresponding terminal. The cascade ports of other sub-switches in the FC switching network may receive the target login synchronization frame repeatedly, so it is necessary to discard the repeated target login synchronization frame until the main switch receives the target login synchronization frame. The main switch also needs to discard the repeated target login synchronization frame.

[0108] In the embodiment of the present invention, after sending the target login synchronization frame to the terminal login information table of the main switch to obtain the whole network login update terminal information table, the method further includes:

[0109] Changing the frame type of the initial general frame to obtain an initial link state response frame;

[0110] Filling the terminal information into the initial link state response frame to obtain a target link state response frame;

[0111] Sending the target link state response frame to the cascade port of the switch through the cascade port of the main switch;

[0112] Determining whether the cascade port of the switch receives the target link status response frame for the first time;

[0113] If the cascade port of the switch does not receive the target link state response frame for the first time, the target link state response frame is discarded;

[0114] If the cascade port of the switch receives the target link status response frame for the first time, the sending of the target login synchronization frame is completed.

[0115] It is understandable that the initial link state response frame refers to a frame to be completed that has a set frame type but has not yet encapsulated terminal information. The target link state response frame (Link State Update, LSA for short) is used for link state response. When the main switch receives the target login synchronization frame, it starts to parse the target login synchronization frame and updates the original terminal login information table. Then, through the cascade port that receives the target login synchronization frame, the target link state response frame is sent to the switch using the cascade ports of other sub-switches in the FC switching network. Similarly, the sub-switch needs to discard the repeatedly received target link state response frame until the target link state response frame is sent to the switch.

[0116] Furthermore, when the switch detects that the connection status of the physical link between the terminal and the switch is abnormal, it is not only necessary to record it in the terminal login information table of the switch, but also to synchronize it to the main switch.

[0117] S7. Receive a logout request from the terminal, send the logout request to the switch, delete the terminal information in the local login update terminal information table of the switch, and obtain a local logout update terminal information table.

[0118] It can be explained that the logout request (Logout, LOGO for short) refers to the communication protocol used when the terminal exits the switch. The local logout update terminal information table refers to the update information table obtained by updating the local login update terminal information table according to the logout operation of the terminal.

[0119] In detail, after receiving the logout request from the terminal and sending the logout request to the switch, the method further includes:

[0120] Changing the frame type of the initial general frame to obtain an initial logout response frame;

[0121] Filling the terminal information into the initial logout response frame to obtain a target logout response frame;

[0122] The target logout response frame is sent to the terminal.

[0123] It should be understood that the target logout response frame (LOGO LS_ACC) refers to the LS_ACC frame that the switch replies to when accepting the terminal logout.

[0124] S8. If the switch is a master switch, the terminal information deleted in the local logout update terminal information table is not forwarded.

[0125] It can be explained that when the switch to which the terminal is connected is the main switch, it is not necessary to synchronize the logout information of the terminal, and the purpose of the main switch maintaining the terminal information of the terminal can be achieved.

[0126] S9. If the switch is not the master switch, the terminal information deleted from the local logout update terminal information table is deleted from the whole network login update terminal information table of the master switch to obtain the whole network logout update terminal information table.

[0127] It should be understood that when the switch is not the main switch, the terminal information deleted from the local logout update terminal information table needs to be deleted synchronously in the whole network login update terminal information table of the main switch. At this time, a synchronization process similar to the target login synchronization frame (Link State Update, referred to as LSU) is required, and the deleted terminal information is encapsulated by constructing a target logout synchronization frame, and then the target logout synchronization frame is sent to the main switch in the same transmission mode as the target login synchronization frame, and then the corresponding terminal information is deleted in the main switch, and then a link state response frame is constructed and sent to the switch to achieve synchronization of terminal logout information.

[0128] Compared with the background technology, the dynamic network information maintenance solution is not universal for different FC protocols and cannot realize the phenomenon of updating the network connection information of networks with multiple FC upper layer protocols. When receiving the login request of the terminal, the embodiment of the present invention uses the switch connected to the terminal to allocate a terminal address to the terminal, and then constructs the terminal information according to the terminal address, the terminal name and the switch identifier. After obtaining the terminal information, it is necessary to store it in the terminal login information table in the switch, so as to obtain a real-time local login update terminal information table. At this time, it is necessary to determine whether the switch is the main switch, and adopt different terminal information update methods according to the different authority positioning of the switch. When the When the switch is the main switch, there is no need to make any adjustments to the terminal information. If the switch is not the main switch, the terminal information needs to be synchronized to the terminal login information table in the main switch to obtain the whole network login update terminal information table. When the logout request of the terminal is received, the first step is to delete the terminal information of the terminal in the switch, and then adopt different measures according to the specific authority location of the switch. If the switch is the main switch, no other operations are required. If the switch is not the main switch, the deleted terminal information needs to be synchronized to the whole network login update terminal information table of the main switch for deletion to obtain the whole network logout update terminal information table. Therefore, the dynamic update method, device, electronic device and computer-readable storage medium based on the terminal connection status of the FC switching network proposed in the present invention can solve the problem that the dynamic network information maintenance solution is not universal for different FC protocols and cannot realize the update of network connection information of networks with multiple FC upper layer protocols.

[0129] like Figure 5 FIG. 1 is a functional module diagram of a dynamic updating device based on FC switching network terminal connection status provided by an embodiment of the present invention.

[0130] The dynamic update device 100 based on the connection status of the FC switching network terminal of the present invention can be installed in an electronic device. According to the functions to be implemented, the dynamic update device 100 based on the connection status of the FC switching network terminal can include a terminal address allocation module 101, a terminal information storage module 102, a terminal login information synchronization module 103, a terminal information deletion module 104 and a terminal logout information synchronization module 105. The module of the present invention can also be called a unit, which refers to a series of computer program segments that can be executed by a processor of an electronic device and can complete fixed functions, which are stored in the memory of the electronic device.

[0131] The terminal address allocation module 101 is used to receive a login request from a terminal, send the login request to a pre-built switch, and use the switch to allocate a terminal address to the terminal;

[0132] The terminal information storage module 102 is used to obtain the name of the terminal and the identifier of the switch, and construct the terminal information according to the terminal address, the name of the terminal and the identifier of the switch; store the terminal information in the terminal login information table of the switch to obtain a local login update terminal information table;

[0133] The terminal login information synchronization module 103 is used to determine whether the switch is a preset master switch; if the switch is the master switch, the terminal information in the local login update terminal information table is not forwarded; if the switch is not the master switch, the terminal information in the local login update terminal information table is sent to the terminal login information table of the master switch to obtain the whole network login update terminal information table;

[0134] The terminal information deletion module 104 is used to receive a logout request from the terminal, send the logout request to the switch, delete the terminal information in the local logout update terminal information table of the switch, and obtain a local logout update terminal information table;

[0135] The terminal logout information synchronization module 105 is used for not forwarding the terminal information deleted in the local logout update terminal information table if the switch is the main switch; if the switch is not the main switch, deleting the terminal information deleted in the local logout update terminal information table from the whole network login update terminal information table of the main switch to obtain the whole network logout update terminal information table.

[0136] In detail, each module in the dynamic update device 100 based on the FC switching network terminal connection status in the embodiment of the present invention is used in the same manner as described above. Figure 3The same technical means as the dynamic update method based on the FC switching network terminal connection status described in the above can produce the same technical effect, which will not be repeated here.
