Enterprise network large file transmission system authorized and managed in centralized mode and method

Abstract

The invention discloses an enterprise network large file transmission system authorized and managed in a centralized mode. The system comprises a client, a service system server and a large attachment server. The client is connected with the service system server, and the service system server is connected with the large attachment server. The client refers to a personal computer host system of a user, and the system is provided with an Internet browser. The service system server refers to a system needing to be deployed for enterprise informatization application, and comprises a content management server, an office email server, a video server and a cooperative office server. The service server comprises a file transmission module and a service function module which are mutually independent. The invention further discloses a large attachment transmission method. By means of the system and the method, large files are transmitted, and the system and the method are high in file transmission speed, simple to use, safe, reliable and convenient. The speed during large file transmission is 2-10 times faster than that of a common file transmission method.

Description

technical field [0001] The invention relates to a large file transmission system and method, in particular to an enterprise network large file transmission system and method with centralized authorization and centralized management. Background technique [0002] With the rapid development of information technology and the continuous deepening of enterprise information applications, the amount of data to be transmitted is increasing. Various large data files must be able to quickly realize network transmission. The problems that enterprise network users often feel headache include the following three Aspects: [0003] 1. The transmission rate of large attachments cannot be controlled. In order to ensure the reliability of large data file transmission, the TCP protocol is used for transmission at the transport layer. However, due to the influence of the congestion control mechanism of the TCP protocol, the transmission rate cannot be controlled, and the fast transmission of hi...

AI Technical Summary

Problems solved by technology

[0003] 1. The transmission rate of large attachments cannot be controlled. In order to ensure the reliability of large data file transmission, the TCP protocol is used for transmission at the transport layer. However, due to the influence of the congestion control mechanism of the TCP protocol, the transmission rate cannot be controlled, and the fast transmission of high-priority files cannot be guaranteed. ;

[0004] 2. Large file transfer is tightly coupled with business processing. When the business system needs to transfer large files, the business system needs to wait for the file transfer to complete before continuing to work. However, large file transfer takes a long time, resulting in waste of resources and low work efficiency ;

[0005] 3. It is difficult to resume the transmission from breakpoints. When a large amount of data files are transferred, the node network is unstable or the power is cut off or the host is restarted, and the file transmission is interrupted. Transfer files from scratch, resulting in waste of bandwidth resources
