[0141] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0142] The multi-device multi-port connection method provided by the present application can be applied to a topological diagram of a multi-device multi-port connection method as shown in Figure 1 Among them, there can be multiple devices. Before each device is connected, the user will set a global variable array. The number of array members is the maximum number of devices that can be supported, and each member corresponds to a connected device to save its device information.

[0143] In one embodiment, as shown in Figure 2 the present invention provides a multi-device multi-port connection method, and the method includes:

[0144] S201. A first target device and a second target device receive device information through a long connection and verify the device information according to a global array set by the user;

[0145] S202. After verifying the device information, the first target device and the second target device receive port information through the long connection;

[0146] S203. The first target device and the second target device connect at least one pair of target port pairs according to the port information, the device information and the global array;

[0147] S204. After connecting the target port pairs, the first target device and the second target device connect the remaining target devices according to the global array and the long connection.

[0148] Specifically, a unified port selection mechanism is used to determine the port pairs that can be used to establish a connection between two devices, so as to realize the establishment of connections between multiple devices and multiple types of ports, improving the practicability and flexibility; a basic network interface is used to establish a long communication to obtain all other port information, avoiding the inability to connect due to the influence of firmware on various devices.

[0149] In one embodiment, before the first target device and the second target device receive device information through a long connection and verify the device information according to a global array set by the user, it includes:

[0150] The user configures the first network interface of the first target device and the second network interface of the second target device, and generates the long connection according to the first network interface and the second network interface.

[0151] Specifically, the user configures the basic network interface IP of the first target device, such as eth0, and configures the basic network interface IP of the second target device, such as eth1, and establishes a socket connection (long connection) between the first target device and the second target device through eth0 and eth1.

[0152] In one embodiment, the first target device and the second target device receive device information through a long connection and verify the device information according to a global array set by the user, including:

[0153] The first target device receives the second device information sent by the second target device;

[0154] Determine whether the first global array of the first target device contains the second device information;

[0155] If so, send the first device information and the first port information to the second target device;

[0156] If not, save the second device information to the first global array and send the first device information and the first port information to the second target device;

[0157] The second target device receives the first device information and the first port information;

[0158] Determine whether the second global array of the second target device contains the first device information;

[0159] If so, send the second port information to the first target device;

[0160] If not, save the first device information to the second global array and send the second port information to the first target device.

[0161] Specifically, such as Figure 3As shown, the first target device designates the second target device to initiate a discovery_req (discovery request) to it via the established long connection, which can be initiated by an instruction or other means. The second target device sends a data packet containing the second device information to the first target device according to this instruction, which should include the message type and local device information, such as: device type, model, name, IP and MAC of the basic network port, etc. The first target device retrieves the members in the global array to determine whether there is second target device information saved due to past connections. If there is, it sends a corresponding data packet containing the first device information and also selects this member to reconnect with the second target device. If not, it selects an unused member in the global array, saves the data packet sent by the designated second target device and sends a data packet containing the first device information to the second target device. After receiving the information, the second target device also first checks in its local global array to see if there is a matching information. If not, it selects an unused member in the global array, saves the received first device information and sends a data packet containing the second device information and an RSCN (rescan) instruction to the first target device again; After receiving it, since the first target device can find the received information in its local global array, it then rescans the port information to prevent information updates and responds to the second target device, and then sends a data packet containing the first device information and the first port information and an RSCN instruction. This data packet should include the message type and all port information of the first target device itself (including port information of FC cards, port information of network cards, etc.). After receiving it, since the second target device can find the received information in its local global array, it rescans the local port information and sends a data packet containing the second port information to the first target device.

[0162] In one embodiment, the connection of at least one pair of target port pairs by the first target device and the second target device according to the port information, the device information and the global array includes:

[0163] The first target device and the second target device determine whether the first target device and the second target device are the same type of device according to the first device information and the second device information;

[0164] If so, connect multiple pairs of the target port pairs according to the port information and the global array;

[0165] If not, connect one pair of the target port pairs according to the port information and the global array.

[0166] Specifically, the first target device and the second target device can be used for one of a WWW server, a database server, a load balancing server, a mail server, a DNS server, a proxy server, a router, etc. For example, when both the first target device and the second target device are used for a proxy server, multiple pairs of target port pairs are selected for connection at this time; when the first target device is used for a mail server and the second target device is used for a router, only one pair of target port pairs between them needs to be selected for connection. The connection between port pairs can be established using protocols such as iSCSI (Internet Small Computer System Interface), FC (Fibre Channel), RoCE (RDMA over Converged Ethernet).

[0167] In one embodiment, the first target device and the second target device connecting at least one pair of target port pairs according to the port information, the device information, and the global array further includes:

[0168] Determining whether the target port pair contains a target port that has been connected to the port of another device according to the port information;

[0169] If so, determining whether the global array of the target device where the target port is located contains the device connected to the target port.

[0170] Specifically, as described above, when the first target device used for a mail server and the second target device used for a router determine to perform a two-way connection of the local network cards, that is, the first target device and the second target device respectively connect to the network card ports in the first target device and the network card ports in the second target device. When the first target device is connected and it is determined that the local network card port has been connected to the network card port of another device such as a database server, it is necessary to determine whether the database server is included in its own global array at this time.

[0171] In one embodiment, determining whether the global array of the target device where the target port is located contains the device connected to the target port includes:

[0172] If so, reusing the target port and connecting the target port pair according to the port information and the global array;

[0173] If not, canceling the connection between the target port and the port of another device and connecting the target port pair according to the port information and the global array.

[0174] Specifically, as described above, if the database server is not included in the global array, that is, the connection to the database server is illegal. At this time, the connection to the database server is cancelled, and the two-way connection with the second target device is continued through the connected network card port. If it is included, it is determined that the network card port is in a one-to-many connection mode. At this time, the network card port is reused to perform a two-way connection with the second target device on the basis of ensuring the connection to the database server.

[0175] In one embodiment, after the connection of the target port pair ends, the first target device and the second target device connect the remaining target devices according to the global array and the long connection, including:

[0176] Determine whether the remaining unconnected target devices are included in the global array;

[0177] When the remaining unconnected target devices are included in the first global array, the first target device starts to connect the remaining target devices according to the long connection;

[0178] When the remaining unconnected target devices are included in the second global array, the second target device starts to connect the remaining target devices according to the long connection.

[0179] Specifically, after the connection between the first target device and the second target device ends, it is determined whether there are unconnected devices in the global array. If so, the remaining unconnected devices recorded in the global array are connected respectively. And after the connection, the target device monitors the connection status in real time. When a connection anomaly is found, a reconnection is initiated. After multiple connection failures, the connection is directly cancelled. The specific number of reconnections and the monitoring frequency are set according to the importance of the target device; when the port information of any one of the two devices at both ends changes, an RSCN notification is sent to the opposite end, so that the opposite end initiates a discovery_req process again, re-obtains the port information and connects to ensure the instant connectivity of the two target devices.

[0180] The solution of the present application has the following beneficial effects:

[0181] 1) Through a unified port selection mechanism, the port pair available for establishing a connection between two devices is determined to realize the establishment of connections with multiple devices using multiple ports, improving the practicability and flexibility;

[0182] 2) Use the basic network port to establish a long communication to obtain all other port information, avoiding the inability to connect due to the influence of firmware on various devices;

[0183] 3) By maintaining real-time communication and port information change notification means, the stability and reliability of the device connection are ensured.

[0184] It should be understood that althoughFigure 2 The steps in the flowchart are shown in sequence according to the arrows, but these steps are not necessarily executed in the order indicated by the arrows.
