It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0028] Figure 1 The present invention provides a flowchart of a link automatic aggregation method. The present invention is applicable to the case where link ports connecting different devices are automatically aggregated. The method can be performed by a link automatic aggregation device, which can be implemented in the form of hardware and / or software and can be configured in an electronic device that implements the link automatic aggregation method. Figure 1 As shown, the method includes:

[0029] S101. Obtain link aggregation information of a first device port based on the LLDP protocol. The first device port is an actual physical interface used to connect devices for communication transmission. The link aggregation information includes: port aggregation performance, port aggregation status, and device classification of the device to which the port belongs. The port aggregation performance is whether the device port supports being configured to perform port aggregation. The port aggregation status is used to indicate whether the device port has been configured in the aggregation group to which it belongs. The device is classified as a master device or a slave device. The aggregation group is a logical port established by multiple device ports belonging to the same device. Port aggregation is to control the device port to be configured in the aggregation group to which the device port belongs.

[0030] In the embodiment of the present invention, the Link Layer Discovery Protocol (LLDP) may refer to a network protocol used for mutual identification between devices and automatic discovery of network topology. Figure 2 ,The actual physical interface may refer to the actual physical port on a device in an Ethernet network, which is used for connection or ,communication transmission between different devices, for example Figure 2 The ports A1, A2, A3, B1, B2, and B3 in Figure 1. An aggregation group can refer to a logical port established for multiple physical ports on the same device, such as Figure 2 Aggregation group A includes ports A1, A2 and A3, and aggregation group B includes ports B1, B2 and B3. Port aggregation may refer to bundling multiple physical ports into an aggregation group. Port aggregation performance may refer to whether a device port has the performance to support port aggregation. Port aggregation status may refer to whether a device port is in a state where port aggregation has been performed and is configured in the aggregation group to which it belongs.

[0031] Specifically, the port aggregation performance, port aggregation state and device classification of the device to which the port belongs of the first device port can be obtained through the LLDP protocol, thereby forming the link aggregation information of the first device port. Exemplarily, the LLDP protocol supports the TLV data encoding format, so the link aggregation information of the device port can be represented in the TLV format. For example, the link aggregation information can be represented by 3 bits in the TLV format, that is, bit 0: aggCap, indicating the port aggregation performance, when the device port supports being configured to perform port aggregation, aggCap=1, otherwise aggCap=0; bit 1: aggStat, indicating the port aggregation state, when the device port has been configured in the aggregation group to which it belongs, aggStat=1, otherwise aggStat=0; bit 2: aggAct, indicating the device classification of the device to which the port belongs, when the device classification of the device to which the device port belongs is a master device, aggAct=1, when the device classification of the device to which the device port belongs is a slave device, aggAct=0. Furthermore, the link aggregation information of the device port can be represented as (aggCap, aggStat, aggAct).

[0032] As an optional implementation of an embodiment of the present invention, link aggregation information of the first device port is obtained based on the LLDP protocol, including: if the first device port supports being configured in an aggregation group, then the port aggregation performance in the link aggregation information of the first device port indicates that the device port supports being configured to perform port aggregation; if the first device port can be controlled to communicate through the aggregation group to which the first device port belongs, then the port aggregation status in the link aggregation information of the first device port indicates that the device port has been configured in the aggregation group.

[0033] Specifically, if the first device port is set to support being configured in an aggregation group, the port aggregation performance of the first device port indicates that the first device port supports performing port aggregation, otherwise the port aggregation performance of the first device port indicates that the first device port does not support performing port aggregation. If the aggregation group to which the first device port belongs can control the first device port to perform connection or communication transmission between devices, the port aggregation state of the first device port indicates that the first device port has completed port aggregation and has been configured in the aggregation group to which the first device port belongs, otherwise the port aggregation state of the first device port indicates that the first device port is not configured in the aggregation group to which the first device port belongs.

[0034] S102. If the link aggregation information of the first device port indicates that the device to which the first device port belongs is classified as a master device, determine whether the link aggregation information of the first device port conforms to preset aggregation information, wherein the preset aggregation information indicates that the port aggregation performance in the link aggregation information indicates that the device port supports being configured for port aggregation and the port aggregation status indicates that the device port is not configured in an aggregation group.

[0035] In the embodiment of the present invention, the preset aggregation information may refer to information preset for determining whether the device port can perform port aggregation. The preset aggregation information may be port aggregation performance indicating that the device port has the performance of performing port aggregation and port aggregation status indicating that the device port is in a state where port aggregation is not performed and is configured in the aggregation group to which it belongs.

[0036] Specifically, according to the device classification of the device to which the port belongs in the link aggregation information of the first device port, it can be determined whether the device classification of the device to which the first device port belongs is a master device. Furthermore, if the device classification of the device to which the first device port belongs is a master device, it can be determined whether the link aggregation information of the first device port conforms to the preset aggregation information according to the port aggregation performance and the port aggregation state in the link aggregation information of the first device port. If the device classification of the device to which the first device port belongs is a slave device, link aggregation is not performed.

[0037] S103. If the link aggregation information of the first device port meets the preset aggregation information, the link aggregation information of the second device port is obtained based on the LLDP protocol. The second device port is connected to the first device port and the second device port and the first device port belong to different devices. The aggregation group to which the second device port belongs can communicate with the aggregation group to which the first device port belongs.

[0038] In the embodiment of the present invention, the second device port may refer to an actual physical interface on a different device from the first device port, and the second device port and the first device port may be connected to form a link, and at the same time, the aggregation group to which the second device port belongs and the aggregation group to which the first device port belongs can communicate and transmit. Figure 2 , ports A1 and B1 are connected, ports A2 and B2 are connected, ports A3 and B3 are connected, and aggregation group A and aggregation group B can communicate.

[0039] Specifically, according to the link aggregation information of the first device port, it can be determined whether the link aggregation information of the first device port meets the preset aggregation information. Furthermore, if the link aggregation information of the first device port meets the preset aggregation information, the port aggregation performance, port aggregation status and device classification of the device to which the port belongs of the second device port can be obtained based on the LLDP protocol to form the link aggregation information of the second device port. The method for obtaining the link aggregation information of the second device port is similar to the method for obtaining the link aggregation information of the first device port. If the link aggregation information of the first device port does not meet the preset aggregation information, link aggregation is not performed.

[0040] Exemplarily, when the link aggregation information of the first device port is represented as (1, 0, 1) in the TLV format of the LLDP protocol, it can be considered that the link aggregation information of the first device port complies with the preset aggregation information.

[0041] As an optional method, link aggregation information of the second device port is obtained based on the LLDP protocol, including: if the second device port supports being configured in an aggregation group, then the port aggregation performance in the link aggregation information of the second device port indicates that the second device port supports being configured to perform port aggregation; if the second device port can be controlled to communicate through the aggregation group to which the second device port belongs, then the port aggregation status in the link aggregation information of the second device port indicates that the second device port has been configured in the aggregation group.

[0042] As an optional implementation manner of an embodiment of the present invention, after obtaining the link aggregation information of the second device port based on the LLDP protocol, it also includes: if the device classification of the device to which the port belongs in the link aggregation information of the second device port is a master device, then determining the device classification of the device to which the port belongs in the link aggregation information of the first device port and the second device port according to the physical addresses of the devices to which the first device port and the second device port respectively belong.

[0043] Specifically, according to the device classification of the device to which the port belongs in the link aggregation information of the second device port, it can be determined whether the device classification of the device to which the second device port belongs is a master device. Furthermore, if the device classification of the device to which the second device port belongs is a master device, the device classification of the device to which the port belongs in the link aggregation information of the first device port and the second device port is determined according to the physical addresses of the devices to which the first device port and the second device port respectively belong. If the device classification of the device to which the second device port belongs is a slave device, the device classification of the device to which the port belongs in the link aggregation information of the first device port and the second device port is not modified.

[0044] Exemplarily, if the physical address of the device to which the second device port belongs is smaller than the physical address of the device to which the first device port belongs, the device classification of the device to which the port belongs in the link aggregation information of the second device port is a master device, and the device classification of the device to which the port belongs in the link aggregation information of the first device port is a slave device. If the physical address of the device to which the second device port belongs is not smaller than the physical address of the device to which the first device port belongs, the device classification of the device to which the port belongs in the link aggregation information of the second device port is a slave device, and the device classification of the device to which the port belongs in the link aggregation information of the first device port is a master device.

[0045] S104: If the link aggregation information of the second device port conforms to the preset aggregation information, control the first device port and the second device port to perform link aggregation, wherein the link aggregation is achieved by controlling the first device port to perform port aggregation and controlling the second device port to perform port aggregation.

[0046] Specifically, according to the link aggregation information of the second device port, it can be determined whether the link aggregation information of the second device port conforms to the preset aggregation information. Further, if the link aggregation information of the second device port conforms to the preset aggregation information, the first device port is controlled to perform port aggregation and the second device port is controlled to perform port aggregation, so as to implement link aggregation for the first device port and the second device port. If the link aggregation information of the second device port does not conform to the preset aggregation information, link aggregation is not performed.

[0047] As an optional implementation manner of an embodiment of the present invention, controlling a first device port and a second device port to perform link aggregation includes: if, during the process of performing link aggregation on the first device port and the second device port, the port aggregation performance in the link aggregation information of the first device port or the second device port indicates that the first device port or the second device port does not support being configured to perform port aggregation, then controlling the first device port and the second device port to exit link aggregation.

[0048] Specifically, during the process of link aggregation of the first device port and the second device port, if the first device port or the second device port does not support port aggregation, it means that the link aggregation information of the first device port or the second device port does not conform to the preset aggregation information. Then, the first device port and the second device port are respectively controlled to exit the port aggregation, thereby realizing exit from the link aggregation.

[0049] As an optional implementation of an embodiment of the present invention, controlling the first device port and the second device port to exit link aggregation includes: if the port aggregation performance in the link aggregation information of the second device port indicates that the second device port does not support being configured to perform port aggregation, then controlling the first device port and the second device port to exit link aggregation and waiting for the link aggregation information of the second device port to meet the preset aggregation information before executing link aggregation again.

[0050] Specifically, during the process of link aggregation between the first device port and the second device port, if the second device port does not support port aggregation, the link aggregation information of the second device port does not conform to the preset aggregation information. Then, the first device port and the second device port are controlled to exit link aggregation, and after waiting for the link aggregation information of the second device port to conform to the preset aggregation information, the first device port and the second device port are controlled to perform link aggregation again, so as to avoid determining again whether the link aggregation information of the first device port conforms to the preset aggregation information.

[0051] As an optional implementation of an embodiment of the present invention, controlling the first device port and the second device port to perform link aggregation includes: determining the order in which the first device port and the second device port perform port aggregation according to the device classification of the devices to which the ports belong in the link aggregation information of the first device port and the second device port.

[0052] Specifically, when controlling the first device port and the second device port to perform link aggregation, the order in which the first device port and the second device port perform port aggregation can be determined by the device classification of the devices to which the first device port and the second device port respectively belong. Exemplarily, the device port of the device to which the port belongs, which is classified as a master device, performs port aggregation before the device port of the device to which the port belongs, which is classified as a slave device. Correspondingly, when controlling the first device port and the second device port to exit link aggregation, if the device port of the device to which the port belongs, which is classified as a slave device, does not support the execution of port aggregation, then the device port of the device to which the port belongs, which is classified as a master device, exits port aggregation, and waits for the link aggregation information of the device port of the device to which the port belongs, which is classified as a slave device, to meet the preset aggregation information and performs port aggregation again.

[0053] As an optional implementation of the embodiment of the present invention, the automatic link aggregation method of the embodiment of the present invention further includes: after the first device port and the second device port complete link aggregation, updating link aggregation information of the first device port and the second device port.

[0054] Specifically, when the first device port and the second device port complete link aggregation, the port aggregation status in the link aggregation information of the first device port and the second device port are updated to indicate that the device port has been configured in the corresponding aggregation group. Exemplarily, when the first device port and the second device port complete link aggregation, when the link aggregation information is represented in TLV format, aggStat is updated to 1.

[0055] The technical solution of the embodiment of the present invention obtains the link aggregation information of the first device port based on the LLDP protocol. The first device port is an actual physical interface used to connect devices for communication transmission. The link aggregation information includes: port aggregation performance, port aggregation status and device classification of the device to which the port belongs. The port aggregation performance is whether the device port supports being configured to perform port aggregation. The port aggregation status is used to indicate whether the device port has been configured in the aggregation group to which it belongs. The device is classified as a master device or a slave device. The aggregation group is a logical port established by multiple device ports belonging to the same device. Port aggregation is to control the device port to be configured in the aggregation group to which the device port belongs. The link aggregation information of the first device port is obtained through the LLDP protocol, which reduces the cost of device operation and maintenance and avoids the occupation of system resources. If the link aggregation information of the first device port indicates that the device classification of the device to which the first device port belongs is a master device, it is determined whether the link aggregation information of the first device port meets the preset aggregation information. The preset aggregation information indicates that the port aggregation performance in the link aggregation information indicates that the device port supports being configured to perform port aggregation. The aggregation and port aggregation status indicates that the device port is not configured in the aggregation group, and it is realized that whether the first device port supports port aggregation is judged through the link aggregation information of the first device port, thereby improving the efficiency of link aggregation; if the link aggregation information of the first device port meets the preset aggregation information, the link aggregation information of the second device port is obtained based on the LLDP protocol, the second device port is connected to the first device port and the second device port and the first device port belong to different devices, and the aggregation group to which the second device port belongs can communicate with the aggregation group to which the first device port belongs, thereby realizing the acquisition of the link aggregation information of the second device port through the LLDP protocol; if the link aggregation information of the second device port meets the preset aggregation information, the first device port and the second device port are controlled to perform link aggregation, and the link aggregation is realized by controlling the first device port to perform port aggregation and controlling the second device port to perform port aggregation, thereby realizing controlling the first device port and the second device port to perform port aggregation, thereby controlling the execution of link aggregation, improving the accuracy of link aggregation, and avoiding service interruption and network paralysis caused by aggregation configuration errors.

[0066] The technical solution of the embodiment of the present invention is to obtain the link aggregation information of the first device port based on the LLDP protocol through the first acquisition module 201. The first device port is an actual physical interface for connecting devices for communication transmission. The link aggregation information includes: port aggregation performance, port aggregation status and device classification of the device to which the port belongs. The port aggregation performance is whether the device port supports being configured to perform port aggregation. The port aggregation status is used to indicate whether the device port has been configured in the aggregation group to which it belongs. The device is classified as a master device or a slave device. The aggregation group is a logical port established by multiple device ports belonging to the same device. Port aggregation is to control the device port to be configured in the aggregation group to which the device port belongs. The link aggregation information of the first device port is obtained through the LLDP protocol, which reduces the cost of device operation and maintenance and avoids the occupation of system resources. The aggregation information judgment module 202 judges whether the link aggregation information of the first device port meets the preset aggregation information when the link aggregation information of the first device port indicates that the device classification of the device to which the first device port belongs is the master device. The preset aggregation information indicates that the port aggregation performance in the link aggregation information indicates that the device port supports being configured to perform port aggregation. The aggregation and port aggregation state indicates that the device port is not configured in the aggregation group, and it is realized that whether the first device port supports the execution of port aggregation is judged by the link aggregation information of the first device port, thereby improving the efficiency of link aggregation; when the link aggregation information of the first device port meets the preset aggregation information, the link aggregation information of the second device port is obtained based on the LLDP protocol through the second acquisition module 203, the second device port is connected to the first device port and the second device port and the first device port belong to different devices, and the aggregation group to which the second device port belongs can communicate with the aggregation group to which the first device port belongs, thereby realizing the acquisition of the link aggregation information of the second device port through the LLDP protocol; when the link aggregation information of the second device port meets the preset aggregation information, the link aggregation module 204 controls the first device port and the second device port to perform link aggregation, and the link aggregation is realized by controlling the first device port to perform port aggregation and controlling the second device port to perform port aggregation, thereby realizing controlling the first device port and the second device port to perform port aggregation, thereby controlling the execution of link aggregation, improving the accuracy of link aggregation, and avoiding service interruption and network paralysis caused by aggregation configuration errors.
