Method and system for batch upgrading of gateways based on WINDOWS and LINUX platforms

Abstract

The invention discloses a method and a system for batch upgrading of gateways based on WINDOWS and LINUX platforms, and relates to the field of communication between cross-platform equipment. The method comprises the following steps of enabling a server to establish the cross-platform bidirectional communication between a server and a client according to an original socket, wherein the server adopts a WINDOWS system, and the client adopts an LINUX embedded type system; enabling the server to dynamically distribute an unique IP (Internet protocol) address for the found client, and establishing TCP (transmission control protocol) connection; enabling the server to check whether the client needs to be upgraded or not; when the upgrading is not needed, finishing the process; when the upgrading is needed, enabling the client to rewrite a file transmission protocol defined in an inner core TCP / IP of the Linux system, splicing fragments of a file into a block, and directly storing into a memory. The method has the advantages that the integrity and correctness of the gateway client receiving the file can be guaranteed, the memory space is saved, the probability of upgrading failure is reduced, and the starting and finishing identifications of upgrading are clearly identified.

Description

Technical field [0001] The invention relates to the field of cross-platform communication between devices, in particular to a gateway batch upgrade method and system based on WINDOWS and LINUX platforms. Background technique [0002] The Linux system is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX (Porttable Operation System Interface of Unix) and Unix. Nowadays, many hardware devices have installed full version or tailored version of Linux system, such as: home gateway, mobile phone, tablet computer, computer, large server, etc. [0003] As a user-side terminal product of triple play, Linux-based home gateways are widely used and demanded. Projects often encounter large quantities (10,000 or more) of new equipment outside. For some reason, when the equipment is stored in the warehouse, the version or configuration needs to be re-upgraded before being applied to home users. Without EMS (Element Management System, graphic network management ...

AI Technical Summary

Problems solved by technology

[0005] (1) There is a problem that the gateway client file is incompletely received

[0006] The upgrade based on the UDP protocol does not support fragment retransmission and verification, so it cannot guarantee that each data fragment sent by the PC can be correctly received by the gateway, and it is difficult to guarantee the integrity and correctness of the files received by the gateway client

[0007] (2) It takes up more space and has a higher probability of upgrade failure

[0009] The traditional two upgrade methods require at least 2 times the remaining space of the image size for upgrade. Due to the limitation of the FLASH size of the embedded system, the probability of upgrade failure is high

[0010] (3) There is no verification mechanism in the traditional upgrade process, which makes the upgrade process unintelligent, and the upgrade start and end marks cannot be confirmed
