The bandwidth capability can be improved by the distributed link aggregation connection among the plurality of network devices. Fig. 1 is a networking schematic diagram of a conventional distributed link aggregation technology, and a network device 1 and a network device 2 form a distributed link aggregation system. The aggregation port1 and the aggregation port2 are used for directly connecting the network device 1 and the network device 2 so as to enable communication between the network device 1 and the network device 2; port1 and port2 are service interfaces that provide link aggregation, which are independent devices that are used to connect external networks. The upper software layer of two network devices has a link aggregation table, the lower driving layer has a link aggregation table, and the bottom hardware layer has a link aggregation table. The link aggregation table stores all available port information for both network devices. When a port link of port1 or port2 is interrupted, under the existing distributed link aggregation technology, the link aggregation table storage unit has a three-layer structure, which is a software layer, a driver layer, and a hardware layer. When each device has a fault, the fault is reported to a software layer, the software layer processes a fault port, the items of the devices are synchronized, and then an update message is sent to a hardware layer. The more devices a distributed link aggregation system has, the more times the software layer is required to synchronize entries. In the prior art, for convergence processing, a link aggregation table of each device needs to be synchronized once in a software layer, and the convergence time is slowed down if the synchronization times are more.

Example 1
As shown in fig. 2, an embodiment of the present invention provides a network convergence method, which is applied to a distributed link aggregation system formed by multiple devices; the method comprises the following steps:
s101, when a hardware layer of a device detects that port state information of the device changes, reporting the change information to a driving layer of the device.
Before S101, the method may further include: and negotiating and selecting one device from the plurality of devices of the distributed link aggregation system as a main device according to a preset rule.
The preset rule may be that the device with the smallest physical identification number or the device with the highest priority of the user interface configuration is selected as the master device.
In the distributed link aggregation system, only 1 master device is provided, and the rest are slave devices. The software layer of the main device stores a real-time software layer link aggregation table. The software layer link aggregation table contains information for all ports as well as some management information.
And if the master device changes, the software layer link aggregation table on the original master device is updated and synchronized to the software layer of the newly selected master device for storage.
The hardware layer can detect whether the port state information on the equipment changes or not through the cycle of the timer, and when the port state information changes from up to down or from down to up, the hardware layer can detect whether the port state information on the equipment changes or not. The hardware layer of the device reports the change information to the driver layer of the device.
And S102, the driver layer of the equipment reports the change information to the software layer of the main equipment selected by the distributed link aggregation system.
And the driver layer of the equipment receives the port state information change information reported by the hardware layer of the equipment and reports the information to the software layer of the main equipment selected by the distributed link aggregation system to which the equipment belongs. When the state of a certain port is changed, the port belongs to the master device and is the master device for sensing, the port belongs to the standby device and is the standby device for sensing, and no matter who senses, the port finally sends the message of the state change of the port to the software layer of the master device.
No matter how many devices are connected, the software layer only has a global software layer link aggregation table stored in the main device. For example: the master device may be elected by the device's system mid or mac, the smallest of which is elected as the master device. And when the master equipment changes, updating and synchronizing the software layer link aggregation table on the original master equipment to the software layer of the newly selected master equipment for storage. Therefore, the number of the link aggregation tables is greatly reduced, and the software layer only has one table and is stored on the main equipment. The core idea is to simplify the link aggregation table, reduce the processing of the link aggregation table as much as possible, improve the convergence speed, simplify the processing flow, and reduce the error risk in the table item synchronization and configuration process.
And the driver layer of the equipment can report the change information to a software layer of the main equipment selected by the distributed link aggregation system through a Netlink message mechanism. The driver layer and the hardware layer belong to the kernel space, and the software layer belongs to the user space. Netlink is a special inter-process communication for enabling user-space processes to communicate with kernel-space processes, and is also the most common interface for network applications to communicate with kernels.
S103, the software layer of the main device updates the link aggregation table of the software layer according to the change information and issues link aggregation table updating information to the driving layers of all the devices.
And the software layer of the main equipment updates a software layer link aggregation table according to the change information. For example: when a port changes from up state to down state, the software layer link aggregation table stored on the software layer of the master device sets the port to disable state, which indicates that the port is not available. When a port changes from down state to up state, the link aggregation table of the software layer saved on the software layer of the master device sets the port to enable state, which indicates that the port is available. After the link aggregation table of the software layer stored in the software layer of the master device is updated, the driver layers and the hardware layers of all the devices need to be notified so that the driver layers and the hardware layers of all the devices can update the corresponding link aggregation table in time to forward the message normally.
And S104, when the driver layer of the equipment receives the link aggregation table updating message, updating the link aggregation table of the driver layer and issuing link aggregation table updating information to the hardware layer of the equipment.
And the software layer of the main equipment issues a link aggregation table updating message to the drive layers of all the equipment. The master device sends a link aggregation table update message to the drive layers of the master device and other used slave devices, all the devices receive the update message and update the drive layer link aggregation table stored on the drive layer of the master device, and simultaneously send the link aggregation table update message to the hardware layer.
And S105, when the hardware layer of the equipment receives the link aggregation table updating message, updating the link aggregation table of the hardware layer so that all the equipment can continuously forward the message according to the updated link aggregation table of the hardware layer.
And the hardware layer of each device receives the link aggregation table updating information sent by the drive layer and updates the hardware layer link aggregation table stored on the hardware layer of the device, when a certain port is changed from the up state to the down state, the port is removed from the hardware layer link aggregation table, and when the certain port is changed from the down state to the up state, the port is added into the hardware layer link aggregation table. And updating the hardware layer link aggregation tables of all the devices so as to continuously and normally forward the message.
