System and method for realizing parallel upgrade of multiple terminals in same IP (Internet Protocol) local area network

Abstract

The invention provides a system and a method for realizing parallel upgrade of multiple terminals in the same IP (Internet Protocol) local area network. The method comprises the following steps of configuring a mapping relation table containing IP characteristics positioned at non-address flag fields in an IP message and a physical port index on a mapping equipment side at the end of a PC (Personal Computer) and transmitting the mapping relation table to the mapping equipment; meanwhile, transmitting a plurality of IP upgrade packets corresponding to different terminals to be upgraded to the mapping equipment by the PC, wherein each IP upgrade packet contains the IP characteristic mapped to the corresponding physical port on the mapping equipment side; thoroughly transmitting through each IP upgrade packet to the corresponding terminal to be upgraded through the corresponding physical port according to the mapping relation table by the mapping equipment; and upgrading the terminal to be upgraded according to the IP upgrade packet. According to the embodiment of the invention, network terminals with the same IP / MAC (Internet Protocol / Media Access Control) are distinguished and accessed by using the non-address flag fields in the IP message and no modification is carried out on the IP message, so that the processing efficiency is increased; and the part using the IP address in an application layer message does not need to be processed, so that the problem of compatibility is solved.

Description

technical field [0001] The invention relates to the field of upgrading Ethernet network equipment and the field of IP protocol communication, in particular to a system and method for realizing parallel upgrading of multiple terminals using the same setting and firmware in the same IP local area network. Background technique [0002] MAC address (Media Access Control Address), also called hardware address or link address, is usually written inside the hardware when produced by network equipment manufacturers. [0003] IP address (Internet Protocol Address), also known as network address, is the way to address hosts on the Internet. It is usually written inside the hardware by the network equipment manufacturer during production, and can be manually modified in subsequent operations. [0004] The IP protocol (Internet Protocol), also known as the Internet Protocol, is a protocol designed for computer networks to communicate with each other. The Internet generally adopts the I...

Problems solved by technology

This solution has higher requirements on the proxy network equipment. The proxy network equipment needs to implement the translation function from IP address to port, and the IP message needs to be modified. Once the TCP or HTTP message is used during the upgrade process, the checksum needs to be recalculated. The modification of the translation of the private IP of the application layer, as well as the fragmentation processing that may be triggered by these modifications, both reduce efficiency and are prone to compatibility issues
