The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
If there are 100 network devices supporting daughter cards in a local area network and the 100 devices support the technology of this patent, each device has 10 daughter cards supporting the technology of this patent.
In the initial state, 100 devices and 500 daughter cards are started, and the master device first collects the information of 10 daughter cards connected below the master device, such as the type of the daughter card and the version number of the daughter card, and records the information. The software of the daughter card can be stored on the daughter card individually, or can be given by the master device each time, and the software version of the daughter card also has the new and old high and low scores.
All the master devices and the daughter cards firstly send a self-defined type of Ethernet message at a low speed, and the message has the following characteristics:
the destination mac address is the multicast mac of the manufacturer using the technology of this patent, and the source mac address is the mac address of the device and the daughter card into which the device is plugged. The ethernet type may be a custom type selected from among unused types. The message content part carries the device type of the message, such as whether the device sending the message is a master device or a daughter card, and the version number of the message, and if the message is the master device, the types of the daughter cards supported by the message, the software and corresponding versions of the carried daughter cards, the configuration information of the message and the network condition of the message are listed. If the daughter card is used, the self-owned software version number and the configuration key are listed.
Because the sent message is a multicast message, in order to prevent the message from flooding in the local area network, the device supporting the technology of the patent limits the speed of the message below or only sends the message to a specific device, because the master device can manage the daughter cards and upgrade the software of the slave devices, the master device only ensures that the message passes through each master device smoothly without passing through each daughter card.
After all the devices and all the sub-cards are synchronized, the device with highest comprehensive network condition, sub-card supporting quantity and performance among 100 main devices in the network serves as a management main device.
After the election is completed, the management master device sends software to the management master device according to the device with the first device type and the highest software version number in the recorded device list, and if the sub-card is located below the management master device, the transmission of the sub-card of the next type is skipped. The second daughter card device type then acts until all daughter card type software is sent to the managing master.
Assuming that 10 daughter card types are totally contained in 500 daughter cards and are all sent to the management main device, the management main device starts the synchronization of the 1 st daughter card type software, and assuming that the software of the management main device has 5000 blocks, the management main device starts broadcasting the 5000 block data into the network, the data is internally provided with check, in order to achieve good reception, the message flooding speed can be adjusted at any time, and the message does not need to be received and confirmed to ensure the transmission speed.
And for the daughter card needing to be upgraded, if the network condition of the daughter card is poor, block storage is carried out by the main equipment where the daughter card is located, otherwise, the daughter card stores the block storage by itself, after 5000 block broadcasts are finished, each received daughter card is upgraded by itself, and the main equipment replaces the received daughter card and transmits the upgrade to the daughter card.
When the 10 types of 500 sub-cards are synchronized by repeating the above method, the management master device broadcasts data to all 500 sub-cards to inquire whether the software reception is normal or not, the sub-card lacking the block independently replies that the management master device lacks the block and needs to retransmit, the management master device instructs the master device which has the sub-card link nearest and feels to send the data to the sub-card independently, and if the device does not exist, the data is sent by oneself.
All 500 daughter card software versions in the local area network are synchronized through the process. And after the synchronous configuration is finished, sending the configuration file of the slave cards to the management main equipment by all 500 slave cards in the local area network in a point-to-point mode, and recording the information of each slave card and the corresponding configuration by the management main equipment for storage.
When the sub-card in the local area network is changed, if the change is the access of a new sub-card and the sub-card of the type exists, the management master device compares the software version number, if the version is lower, the new sub-card is upgraded, and if the version of the sub-card is higher, the software is transmitted to synchronize all the sub-cards of the same type by the method mentioned at the beginning.
After the daughter card change software is synchronized, if the type of the daughter card is the same as that of the daughter card before the change, the management master device sends the configuration file of the old daughter card to the daughter card through point-to-point.
When all the devices and the daughter card devices in the local area network are idle, keep the devices available by sending keep-alive messages to each other periodically, if the master management device has a fault, reselecting a master management device in the local area network, and repeating the steps.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
