Software download method

Abstract

The present invention discloses a software download method comprising steps below: A. Software data section sequence is downloaded, during which a software provider terminal marks position information of data currently downloaded in the whole software. A software demand terminal locates and saves the downloaded data according to the position information; B. In case of abnormal currently downloaded data, the software provider terminal secondly downloads current data to the software demand terminal according to the position information corresponding to the currently downloaded data. The present invention can improve success rate of software download, reduce download time and save network bandwidth resources.

Description

technical field [0001] The invention relates to network communication technology, in particular to a remote software download method in network communication. Background technique [0002] Gigabit Passive Optical Network (GPON) technology is a broadband passive optical network technology. Figure 1 is a topology diagram of a GPON system. Referring to Fig. 1, in the GPON network, the access network equipment is the central office equipment, that is, the optical line terminal (OLT, Optical Line Terminal), and the OLT is generally placed in the central office equipment room; and the terminal equipment is the optical network terminal (ONT, Optical Line Terminal). Network Terminal) are placed far away from the computer room according to different application requirements, and are relatively scattered. The OLT and ONT are connected through an optical splitter. [0003] In order to facilitate the maintenance of ONT equipment, the implementation plan of the GPON system proposes a ...

[0010] However, since the prior art does not have information that can reflect the position of the software data currently being downloaded in the entire software version in the message related to downloading, in the process of downloading software data, if a piece of software data is downloaded If the OMCI message is lost, the location of the current data cannot be determined, so the download of the current software will be terminated, causing the current software download to fail, and the download cannot be resumed automatically

Therefore, the download success rate of the software in the prior art is low; if you want to continue downloading the software, you need to download the entire software from scratch, and the previously downloaded content will be cleared by the ONT, which will also cause download time and network bandwidth. waste of resources
