Description

Technical field

Embodiments of the present invention relate to the field of network communication technology, and specifically to an equipment upgrade method, device, electronic equipment and storage medium.

Background technique

With the development of network technology, the communication architecture of network equipment is becoming more and more complex, and multi-layer and layer-by-layer connected device groups often appear. Currently, the common methods for upgrading the devices in this multi-layer and layer-by-layer connected device group are: Single device upgrade and multi-device batch upgrade. The main steps of single device upgrade are: each device obtains a complete upgrade data package and then performs the upgrade. If the upgrade data package obtained by the device is incomplete, it repeatedly requests the upgrade data package from the upper layer. It can be seen that the upgrade efficiency of this method is low. The main steps of multi-device batch upgrade are: the management server delivers the upgrade data packets required for batch upgrade of devices at one time, and the devices are connected layer by layer through multiple layers to forward the data layer by layer. Each device obtains the complete upgrade data. After receiving the package, you can upgrade and restart. However, after the upper-layer connected device completes the upgrade and restarts, the connection with the lower-layer device will be interrupted. If the lower-layer device has not received the upgrade data at this time, it needs to request the data package again. This results in inefficient upgrades.

It can be seen that a new method of upgrading multi-layer connected devices layer by layer is currently being used.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

Figure 1 is a flow chart of a device upgrade method according to an exemplary embodiment. Referring to Figure 1, the method includes the following steps:

S101. The first device obtains an upgrade data packet and sends the upgrade data packet.

Wherein, the first device is a non-bottom device among the multi-layer-by-layer connection devices.

S102: The first device determines whether it has received successful upgrade instructions from all devices on the next layer based on the MAC topology structure.

S103: After receiving the upgrade success instructions of all devices on the next layer, the first device restarts to complete the device upgrade, and sends the upgrade success instructions to the device on the upper layer.

In the embodiment of the present invention, the upgrade data packet obtained by the first device may be an upgrade data packet from the device upgrade management server or proxy device forwarded by the upper layer device.

Among them, in the video network scenario, when the multi-layer layer-by-layer connection device is a video network device, the device upgrade management server can also be used to first configure the MAC address of the video network device to ensure the legalization of the video network device. And manage device upgrades of video networking devices.

In the embodiment of the present invention, the multi-layer layer-by-layer connection device is: a device group including multiple devices at different levels, and the devices between each layer are connected layer by layer. Specifically, the communication connection between the first-layer device and the device upgrade management server can be as follows: the first-layer device is connected to a first number of second-layer devices, and each second-layer device is connected to a second number of third-layer devices. ,So on and so forth.

In the embodiment of the present invention, the device upgrade management server can determine each device that needs to be upgraded and its upgrade data package. Among them, the upgrade data package of each device that needs to be upgraded can be the same or different.

In the embodiment of the present invention, before sending the upgrade package to the first device for upgrading, the device upgrade management server may also send an upgrade instruction to the corresponding first device, and then perform device upgrade control after obtaining a reply from the first device.

In the embodiment of the present invention, before the first device performs device upgrade, it needs to receive an upgrade data packet from the device upgrade management server through a multi-layer communication architecture that connects the devices hierarchically.

In the embodiment of the present invention, during the transmission process of the upgrade data packet from the device upgrade management server to each device, the device upgrade management server can directly send the upgrade data packet of each device to the corresponding device. In this process, multiple The layer device forwards the upgrade packet layer by layer to the destination device.

Among them, during the forwarding process of the upgrade data packet at each level, the first device can obtain the upgrade data packet, that is, send the upgrade data packet to the device at the next level, so that the device at the next level can receive the upgrade data packet in time. .

In the embodiment of the present invention, during the transmission process of the upgrade data packet from the device upgrade management server to each device, the device upgrade management server can also establish a transmission channel for the device upgrade management server to each device, and the device upgrade management server sends the data through the transmission channel. For the upgrade data packages of all devices, each device can download the upgrade data it needs based on the device identification (such as MAC address, video network number, etc.) corresponding to each upgrade data. Among them, during the data transmission process, devices at each level can receive data from the upper level in the form of data streams and send them to the devices at the next level, and obtain the upgrades they need from the received upgrade data packets. data package, so that all devices can quickly obtain the upgrade data package they need and perform upgrade and restart.

In the embodiment of the present invention, during the transmission process of the upgrade data packet from the device upgrade management server to each device, the device upgrade management server can also determine all sub-devices corresponding to each device located on the first layer according to the network architecture of the multi-layer device. , sending the upgrade data of the device located on the first layer and the upgrade data of all its sub-devices as upgrade data packets to the device on the first layer, so that the device on the first layer serves as a proxy device to distribute the upgrade data. Among them, during the data transmission process, the first-layer device, as a proxy device, can distribute upgrade data packets within the LAN connection corresponding to the multi-layer layer-by-layer connection device, even if the connection before the device upgrade management server is interrupted, Data distribution can also be achieved, and the entire data distribution does not require equipment upgrades and the network bandwidth limitations of the management server.

In the embodiment of the present invention, the upgrade success command carries the MAC address of the corresponding device. The first device can determine all devices on the next layer directly connected to it based on the MAC topology, and then determine whether it has received successful upgrade instructions for all devices on the next layer.

In the embodiment of the present invention, the first device may also add the MAC addresses of all devices on the next layer to the upgrade success command based on the received upgrade success instructions of all devices on the next layer and send it to the upper layer device. Therefore, the upgrade success instruction received by the device on the first layer among the multi-layer-by-layer connection devices carries the MAC addresses of all devices in the entire multi-layer-by-layer connection device. Therefore, after the first-layer device obtains the upgrade success instruction, it can determine the MAC addresses of all successfully upgraded sub-devices.

In the embodiment of the present invention, through the MAC topology and the upgrade success command from the device at the next level, it can be determined whether all the devices at the next level have successfully received the upgrade data packet and completed the upgrade and restart.

In the embodiment of the present invention, in multi-layer connected devices layer by layer, devices at different layers are connected in series layer by layer. Therefore, when the upper layer device is restarted, the lower layer device will be disconnected. If the lower layer device is restarted, the lower layer device will be disconnected. When the device has not received the complete data packet, the restart of the upper device will cause the first lower device to fail to receive the data packet. Based on this, the embodiment of the present invention proposes that after receiving the upgrade data packet, the first device can perform the upgrade first without affecting the communication between the upper and lower layers during the upgrade process, but does not restart. After determining that the device at the next layer is successful, Restart after receiving the upgrade packet and the upgrade is successful. In the case where the upgrade process may affect the communication between the upper and lower layers, the first device will not perform the upgrade after receiving the upgrade data packet. It will then perform the upgrade after it is determined that the device at the next layer has successfully received the upgrade data packet and the upgrade has restarted successfully. Restart.

During the specific implementation, the equipment at each layer will restart to complete the device upgrade after confirming that the device at the next layer has been successfully upgraded, and send an upgrade success command to the device at the upper layer. This can ensure that each layer of multi-layer connected devices is connected layer by layer. All devices were successfully upgraded.

In an optional implementation manner of the present invention, when the first device is a device of the last layer among multiple layer-by-layer connected devices, the first device determines that the current device is a multi-layer device based on the MAC topology. Connect the device at the last layer of the device layer by layer; upgrade the device after obtaining the upgrade data packet, restart the device after the upgrade is completed, confirm the device upgrade is completed after the restart is successful, and send an upgrade success command to the upper layer device.

In the embodiment of the present invention, for the lowest-level device, it can determine the topological structure level where it is located by querying the MAC topology structure. After determining that it is the lowest-level device, it can perform the following steps after receiving the upgrade data packet: After the device is upgraded, it can be restarted immediately, and the upgrade success command will be sent to the device on the upper layer. The device on the upper layer can also query the MAC topology to determine all the devices on the lower layer it is connected to. After receiving the upgrade success instructions sent by all the devices on the next layer, confirm that the upgrade data packets of the devices on the next layer are successfully received and the upgrade is successful. You can restart, complete the device upgrade, and send the first-level success command to the upper layer. equipment.

In the embodiment of the present invention, each of the multi-layer-by-layer connection devices is based on a MAC address learning algorithm and records the corresponding relationship between each MAC address and port according to the received and sent data frames to complete the multi-layer by-layer connection. Topology discovery of connected devices, obtaining MAC topology.

Specifically, each device in the multi-layer layer-by-layer connection device can implement a topology discovery algorithm internally to complete the topology discovery of network devices. In the embodiment of the present invention, the topology discovery of each device is mainly based on the MAC address learning algorithm. By recording the corresponding relationship between each MAC address and the port, a MAC address table of the layer 2 switching network is constructed, thereby determining the MAC topology structure.

Specifically, the first device receives MAC frames from other devices (such as hosts, routers, etc.) on the port, and constructs the frame by reading the source MAC address and destination MAC address in the frame, as well as some other information (such as VLAN tags, etc.) MAC address table. When the first device receives a frame with an unknown destination MAC address, it broadcasts the frame on all ports except the source port to find the destination device. If the destination device replies with a frame to the first device after receiving the broadcast frame, the first device adds the combination of source MAC address, destination MAC address, and receiving port to the MAC address table. In this way, the first device can gradually learn the topology structure of the entire network, build a MAC address table, and then determine the MAC addresses of the first device at the upper layer and/or lower layer to which it is connected. Therefore, it can be determined based on the MAC address and network topology carried in the received upgrade success command whether the upgrade data packet of the first device on the next layer is received successfully, and after the upgrade is restarted successfully, the upgrade data packet of the first device on the next layer can be determined based on the network topology. A device sends an upgrade success command so that the first device at the upper layer can determine the upgrade data packet reception status.

In practical applications, when the method is applied to a video network scenario, the video network device can determine the level of the device based on the MAC topology. After the upgrade is completed, the bottom device that is farthest from the device upgrade management server will be executed first. Upgrade and restart, and send an upgrade success command to the upper-layer visual networking device. The upgrade success command carries its MAC address. Then the upper-layer device receives the upgrade success command from the next-layer device, performs a restart, and sends an upgrade success command to Move up one layer of equipment, and then restart the equipment layer by layer to ensure that the entire network topology device successfully receives the upgrade data packet and performs the upgrade restart, completing the batch upgrade of the equipment.

In the embodiment of the present invention, when the device is a visual network device, the visual network device can obtain its own visual network number and the visual network number of the connected sub-device after accessing the visual network. Based on this, the upgrade success command can also carry its own visual network number, so that the upper layer device can determine the next layer based on the visual network number carried in the received upgrade success command and the visual network number of its connected sub-device. Whether the equipment is completely upgraded.

Figure 2 is a flow chart of a device upgrade method according to another exemplary embodiment. Referring to Figure 2, the method includes the following steps:

S201. Determine the live broadcast channel corresponding to the first device. The live broadcast channel is established based on the information of each device on the transmission path from the device upgrade management server to the first device.

S202: Receive and send the upgrade data packet from the device upgrade management server through the live broadcast channel.

S203: When it is determined that the complete upgrade data package corresponding to the first device has been received, save the obtained complete upgrade data package.

S204: The first device determines whether it has received upgrade success instructions from all devices on the next layer based on the MAC topology structure.

S205: After receiving the upgrade success instructions of all devices on the next layer, the first device restarts to complete the device upgrade, and sends the upgrade success instructions to the device on the upper layer.

In order to facilitate understanding, the explanation will be given by taking the multi-layer layer-by-layer connection device as a visual networking device as an example:

In the embodiment of the present invention, after the video network device accesses the video network, it can obtain its own video network number and the video network number of the connected sub-device. In the embodiment of the present invention, the first-layer video network device can communicate directly with the device upgrade management server through the video network, so that the video network number of the device upgrade management server can be obtained through the heartbeat data from the device upgrade management server, and then the video network number of the device upgrade management server can be obtained. The own video network number and the video network number of the sub-device are encapsulated and uploaded to the device upgrade management server through the SNMP protocol. The device upgrade management server obtains the device information and performs SNMP analysis, extracts the video network number of the first-layer video network device and the video network number of the sub-device, and manages the device status and device information of each video network device.

Specifically, in the embodiment of the present invention, when the device upgrade management server determines that the video network device needs to be upgraded, the device upgrade management server issues an upgrade instruction, and the video network device receives the upgrade instruction and extracts the video network number of the device upgrade management server. , send an upgrade package download request based on the video network number. The upgrade package download request carries the video network number of each video network device. After the device upgrade management server receives the upgrade package download request, it sends a request from the device upgrade management server to the video network device based on the video network number. The video network number of each video network device on the transmission path creates a live broadcast channel, and sends the corresponding live broadcast channel number to the video network device. After receiving the live broadcast channel number, the video networking device waits to receive data based on the corresponding live broadcast channel.

In the embodiment of the present invention, the live broadcast channel is established based on the information of each device on the transmission path from the device upgrade management server to the first device. Therefore, each device in the multi-layer-by-layer connection devices can use data streams layer by layer. The data is received and forwarded in a form so that all devices can quickly receive the upgrade data packet.

Specifically, the device upgrade management server can transmit the upgrade data packets of all video network devices in the live broadcast channel based on the method of publishing live broadcast. Each video network device receives and forwards the upgrade data packet sent by the device upgrade management server, and obtains and saves its own upgrade data during the entire data transmission process. After each video network device has received the data and checked that the data is complete, then check the network topology location, wait for the upgrade success command sent by the next layer of video network equipment, and restart after obtaining the upgrade success command of the next layer of video network device. After the device is upgraded and restarted successfully, the upgrade success command is sent to the first device on the upper layer.

In the embodiment of the present invention, during the process of obtaining upgrade data through the live broadcast channel, the device upgrade management server can continuously send the upgrade data packets required by all video network devices, and each device can wait to obtain all the upgrade data it needs through the live broadcast channel. The required complete upgrade data package is required to improve the upgrade success rate.

Figure 3 is a flow chart of a device upgrade method according to another exemplary embodiment. Referring to Figure 3, the method includes the following steps:

S301: The first device receives an upgrade data packet from the proxy device sent by the device at the upper layer; obtains and saves the first upgrade data packet corresponding to the first device from the upgrade data packet.

S302: Send the upgrade data packets except the first upgrade data packet in the upgrade data packet to all devices on the next layer.

S303: The first device determines whether it has received successful upgrade instructions from all devices on the next layer based on the MAC topology structure.

S304: After receiving the upgrade success instructions of all devices on the next layer, the first device restarts to complete the device upgrade, and sends the upgrade success instructions to the device on the upper layer.

In the embodiment of the present invention, when the device upgrade management server is used to upgrade the video network device, the device upgrade management server is required to perform data transmission for each video network device. The device upgrade management server is required to have high data processing performance and data transmission occupancy. The bandwidth is large and the hardware and software requirements for the device upgrade management server are high.

The embodiment of the present invention also proposes to use the first-layer visual networking device as a proxy to obtain the upgrade data package from the device upgrade management server, and then use the first-layer visual networking device and the network topology structure to update the lower-layer visual networking sub-devices. Distribute upgrade data packages to complete the upgrade of lower-layer devices.

Specifically, in this case, the device upgrade management server can set the first-layer device as a proxy device according to the network topology. The device upgrade management server can issue batch upgrade instructions to the agent device. The agent device can extract the device upgrade management server identifier, apply to receive upgrade data, send a download start request to the device upgrade management server, and send upgrade instructions to its connected sub-devices. , the sub-devices from the second to the Nth layer receive the upgrade instruction and wait.

In the embodiment of the present invention, technicians can also check the network topology of multi-layer connected devices layer by layer, determine the first layer device and set it as a proxy device, and upload the upgrade data packets of all sub-devices of the proxy device to The agent device.

In the embodiment of the present invention, the upgrade data package is distributed in the form of a proxy device, so that batch offline upgrades within a multi-layer layer-by-layer connection device architecture can be completed.

In the embodiment of the present invention, after receiving the download request, the device upgrade management server creates a connection with the first-layer device, and sends the upgrade package data of the first-layer device and all its sub-devices to the first-layer device. The first-layer device receives the data and saves it. The devices at the first layer can obtain the upgrade data they need and send other data packets to the devices at the next layer. The devices at the next layer can also obtain the upgrade data they need and send other data packets to them. Send it to the device at the next level, and so on, to complete the distribution of upgrade data for all sub-devices. In the embodiment of the present invention, during the process of forwarding the upgrade data packet layer by layer among the sub-devices of the proxy device, the data volume of the upgrade data packet can also be reduced layer by layer, thereby improving data distribution efficiency.

In the embodiment of the present invention, after each device obtains the corresponding upgrade data, it can also check the upgrade data. If it is determined that the upgrade data is complete, it will perform the upgrade. If the upgrade data is incomplete, it will proceed to the next level. The device re-requests upgrade data.

In the embodiment of the present invention, even if there is no device upgrade management server, batch upgrades of devices can be completed through a local area network of multi-layer devices. The devices on the first layer in the network topology are designated as proxy devices and the upgrade data packets are uploaded. To the agent device, each device in the multi-layer device delivers upgrade packages layer by layer according to the network topology, completing batch upgrades of lower-layer devices.

In an optional implementation manner of the present invention, in the device upgrade method provided in any of the above embodiments, in the case where the first device is a device on the first layer among multiple layer-by-layer connection devices, the The above methods may also include:

After the first device restarts successfully, it sends an upgrade status update instruction; the upgrade status update instruction carries the MAC address of the first device, so that the first device upgrade management server , the network topology relationship of multi-layer connected devices layer by layer, and the upgrade status of all sub-devices of the first device is updated.

In the embodiment of the present invention, the video network device on the first layer obtains the upgrade success command, and after restarting, sends the upgrade success command to the device upgrade management server. The upgrade success command can carry the mac of all sub-devices connected to it. Address and/or video network number, so that the device upgrade management server can update the device status of each device.
