The invention provides a POE set implementation method based on NVR and IPC, and the method comprises the steps: setting unique UID information for each piece of NVR and IPC equipment in the production process of the NVR and IPC equipment; the UID information of each IPC device is set in each channel of the NVR device, and the UID information of the corresponding NVR device is preset in each IPC device; after the NVR equipment is started, configuring double IP addresses of an intranet and an extranet on a network port; an interface of an LAN Switch chip is utilized, an NVR intranet and an IPC network port of the LAN Switch are divided into VLAN1 to serve as an intranet, and an NVR extranet and an extranet port of the LAN Switch are divided into VLAN2 to serve as an external local area network interface; and the NVR device automatically searches the IPC device in the intranet, and automatically adds the searched IPC device to the corresponding channel according to the preset UID information to complete automatic networking. Through equipment pre-binding, double-IP address allocation, VLAN isolation, an automatic broadcast search mechanism and the like, plug-and-play networking of the set equipment is realized, and meanwhile, the intranet security and the equipment management efficiency are guaranteed.

This invention relates to a distributed optical signal multi-path cross-connection and aggregation device and its implementation method, including a PC host computer, a main control card, cross-connect card 1, cross-connect card 2, and several service cards. The main control card is connected to the PC host computer for socket communication. The main control card is connected to the cross-connect cards and several service cards through a LAN switch for socket communication. Signal transmission between cross-connect cards 1 and 2 and the service cards is achieved through channel groups in the sending and receiving directions. In the sending direction, signals are sent from cross-connect cards 1 and 2 to the service cards; in the receiving direction, the cross-connect cards receive signals sent from the service cards. The number of channel groups from cross-connect cards 1 and 2 to each service card is the same. The distributed strategy solves the problem of algorithm serialization.

The invention discloses a firmware upgrading method, system and device for a local area network switch, and relates to the field of communication, and the method comprises the steps that a server-side BMC obtains network architecture information in the starting process of the server-side BMC, and determines an upgrading mark of firmware of the local area network switch; wherein the network architecture comprises a multiplexer; the server-side BMC confirms whether to execute an upgrading process or not based on the upgrading sign; wherein if the upgrading mark is that the new firmware is not burnt or the burning is unsuccessful, the server-side BMC executes an upgrading process based on the multiplexer and the network architecture information; and if the upgrading mark is that the new firmware is burnt successfully, the server-side BMC determines to end the upgrading process. According to the method and the device, the technical problem of low efficiency of firmware upgrading under the network architecture formed by the machine head server and different BOXs by adopting related technologies is solved, and the technical effect of improving the efficiency of firmware upgrading under the network architecture formed by the machine head server and the different BOXs is achieved.

The application discloses a data communication method and an electronic device, which are applied to a target centralized management controller constructed based on a logic device in a multi-node server, and relate to the technical field of data communication, and the method comprises the following steps: obtaining and analyzing a target data packet of a local area network switch through the logic device in a communication time period, and saving the target data packet into a register of the logic device; if it is monitored that the logic device or the local area network switch is reset or firmware is upgraded before the analysis is completed, the register is cleared, the target data packet is re-obtained and analyzed, and until the target data packet is completely analyzed and saved into the register, the analyzed data is sent to a node management controller to adjust the network port state of the corresponding node. In the communication time period, data is obtained and analyzed through the logic device, and the register is cleared when the logic device or the local area network switch is reset or firmware is upgraded, so that the control logic can be ensured to normally operate while the error data is emptied, and data analysis confusion is avoided.
