A method and device for transferring files based on ftp protocol

Abstract

The invention provides a method and a device for transferring files based on a file transfer protocol (FTP). The method specifically comprises that a network administrator receives trap message reported by base stations; the network administrator determines report performance file time migration of the corresponding base stations according to physical identities (ID) of the base stations in the trap message; the report performance file time migration is used for expressing the migration of the actual time for reporting performance files relative to the theoretical time for reporting the performance files, and the quantity of the base stations with the same report performance file time migration does not exceed half of the connection quantity limited by an operating system; the network administrator transmits request massage carrying the report performance file time migration to the corresponding base stations; and an FTP server of the network administrator returns response codes to the base stations according to SOCKET connection requests of the base stations, and receives the performance files uploaded by the base stations. By the method and the device, resources occupied by a memory of the FTP server can be reduced, and the performance file uploading instantaneity is improved.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a method and device for transferring files based on the FTP protocol. Background technique [0002] FTP (File Transfer Protocol, FileTransferProtocol), as a transfer protocol for network shared files, is widely used in network application software. The goal of the FTP protocol is to improve file sharing and transfer data reliably and efficiently. [0003] At present, the mobile network management specification requires network elements to report performance data according to a predetermined time granularity (5 / 15 / 30 / 60 minutes), generally 15 minutes by default. Usually, the performance data is in file format. At 0 minutes, 15 minutes, 30 minutes, and 45 minutes of each hour, all base stations will generate performance files. The base stations act as FTP clients and create them with the FTP server on the network management side in passive mode. SOCEKT (so...

Here, the semi-connection mainly refers to the session that has not yet fully established the connection (TCP needs to complete the three-way handshake to fully establish the connection), and the SYN attack is realized by forging such a semi-connection, thereby consuming network resources to achieve the purpose of the attack

[0013] However, for TD-SCDMA (Time Division Synchronous Code Division Multiple Access technology, TimeDivision-SynchronousCodeDivisionMultipleAccess) or LTE (Long Term Evolution, LongTermEvolution) system, the number of physical base stations that the network management needs to manage is very large (usually between 3000 and 6000), and When the performance files of the entire network are uploaded, it is easy for the FTP clients of all base stations to request SOCKET connections to the FTP server. In this way, the connection requests of the FTP clients of all base stations will cause the FTP server on the network management side to occupy a large amount of memory; Moreover, the limitation of the number of semi-connections by the operating system of the FTP server on the network management side will lead to the failure of the establishment of FTPSOCKETs that exceed the limit of semi-connections of the operating system. In this way, a large number of performance files cannot be uploaded to the network management system within the specified time, resulting in performance data upload failures. low real-time
