Problems solved by technology

One is to set up an FTP or TFTP server on the PC side, set up a corresponding FTP or TFTP client on the Layer 2 switching device side, and download and obtain the upgrade data from the client side to implement the upgrade. This upgrade method can only upgrade the data of a single device; Another method is to set up an FTP or TFTP server on each Layer 2 switching device. The PC uses the corresponding FTP or TFTP client to log in to the server and upload the upgrade data to implement the upgrade. This upgrade method can use multiple network cards to realize data upgrade of multiple devices. ; but the upgrade cost is relatively high

Embodiment Construction

[0008] refer to figure 1 As shown, the present invention mainly includes a batch data upgrade tool at the PC end and a data upgrade detection program at the Layer 2 switching device end. A method for implementing batch data upgrade of Layer 2 switching devices according to the present invention, the method is specifically: connecting a plurality of Layer 2 switching devices to a switch, and the switch is connected to a PC end; the PC end is provided with a batch A data upgrade tool, which can upload batch data regularly; the batch data upgrade tool is designed through the class library MFC; the PC end uses the WinPcap open source library to realize the data link layer data transmission and reception, and the two-layer switching device end uses the original The socket RAW SOCKET realizes the data link layer data sending and receiving; The upgrade data transmission is carried out through a UCP protocol between the PC end and the two-layer switching device to complete the upgrade...

Abstract

The invention provides a method for achieving batch data upgrade on two-layer switching devices. The method specifically comprises the steps that the multiple two-layer switching devices are connected with an interchanger which is connected with a PC terminal, the PC terminal is provided with a batch data upgrade tool which can upload batch data regularly, the PC terminal achieves data receiving and transmitting of a data link layer through a WinPcap open source bank, the two-layer switching devices achieve data receiving and transmitting of the data link layer through an original socket RAW SOCKET, upgrade data are transmitted between the PC terminal and the two-layer switching devices through a UCP, and then the batch data upgrade is completed. The UCP is an upgrade communication protocol and is a control protocol of the data link layer, the packet format of communication data packets of the batch data upgrade tool and the two-layer switching devices is defined, and the whole process of upgrade communication conversations is specified. By means of the method, resources are saved and upgrade efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a method for implementing batch data upgrade for Layer 2 switching equipment. Background technique [0002] WinPcap is an open source library based on the Win32 platform for capturing and analyzing network packets. The function of the WinPcap open source library can be used to access the original data packet, which is a data packet that has not been processed by the operating system using the network protocol. The socket under the Linux system uses the AF_PACKET protocol cluster, and the RAW_SOCKET type port can directly communicate with the network card driver, which can bypass the protocol stack above IP. RAW SOCKET, that is, a raw socket, can receive data frames or data packets on the local network card. The difference between raw sockets and other sockets is that it works at the network layer or data link layer, while other types of sockets work at the trans...
