A method for implementing batch data upgrade for layer 2 switching equipment

Abstract

The present invention provides a method for implementing batch data upgrade for layer 2 switching equipment, specifically, the method is as follows: connecting multiple layer 2 switching equipment with a switch, and connecting the switch with a PC terminal; the PC terminal is provided with a batch Data upgrade tool, which can upload batch data regularly; the PC end uses the WinPcap open source library to realize the data link layer data sending and receiving, and the second-layer switching device uses the original socket RAW SOCKET to realize the data link layer data sending and receiving; Carry out the transmission of upgrading data through a UCP protocol between the described PC end and the two-layer switching equipment, to complete the upgrading of batch data; Described UCP agreement is the upgrading communication agreement; UCP agreement is the control agreement of a data link layer, defines There is a batch data upgrade tool and the packet format of the communication data packet at the end of the Layer 2 switching device, which standardizes the entire process of upgrading the communication dialogue. The invention not only saves resources, but also improves upgrading efficiency.

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...

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
