The increase of data is the inevitable development of science and technology, and the big data brought by the progress of the times is both an opportunity and a challenge. For the problem of slow transmission of big files, we should think: Is the big data itself or the improper way to deal with the data the root cause of enterprises falling into the dilemma of big data? 1. The challenges brought by big data to file transfer 1) Large Amount of Data How big is the amount of data? Now, the files basically start at GB level, and TB and PB files can be said to be the most frequently encountered file transmission units in the office of medium and large enterprises. 2) Low Transfer Efficiency The amount of data increases, the existing network bandwidth is limited, and the network is congested. If we encounter the situation of weak network, long-distance, trans-provincial and trans-national, the transmission speed of large files is simply terrible, and the trans-national transmission of 10GB files may take several tens of hours. 3) High Risk Network security threats have caused the cost of data leakage to soar. Exposure of sensitive data in the process of data transmission and enterprise interaction; The cloud storage associated with file transfer status and the operation of office workers all have potential risks of data leakage. 2. The Solutions 1) Improve the work efficiency via a large file transfer tool Professional file transfer tool software has perfect countermeasures on packet loss, latency, and transmission efficiency of large file transfer, which can greatly improve work efficiency. For example, Raysync, which is equipped with Raysync high-speed transmission protocol and intelligent compression technology, can meet the high-speed transmission requirements of ultra-remote, cross-border large files, and massive small files, and at the same time make full use of the existing bandwidth of the network to effectively reduce the impact of network latency and packet loss. 2) Select one of the most ideal transfer modes Point-to-point, multi-point mutual transmission, data cloud transmission, one-to-many data distribution, and other modes are often needed in enterprise offices, but there are few large file transmission tools that can really meet the above requirements. Raysync supports providing multiple modes of transmission according to different transmission initiators, and enterprises can intelligently choose according to actual needs. 3) Strengthen storage function and pay attention to software compatibility To solve the problem of file storage in the process of large file transmission, Raysync supports the mainstream cloud platform operating systems such as Alibaba Cloud, Amazon Cloud, Huawei Cloud, etc., and provides special SDK integration products, which can be quickly integrated and deployed with the existing systems of enterprises, and easily build an automated file transmission network for network environments and heterogeneous systems within or between enterprises. 4) Bank-standard security protection and global central control In order to ensure the security of data transmission and prevent data leakage, cracking, monitoring, and other security issues, Raysync strengthens the security control of internal data communication, adopts AES-256 encryption technology of online banking, and uses SSL encryption transmission in the transmission process to effectively ensure data security. At the same time, Raysync adopts the setting of access rights and OS rights, thus achieving stricter access control.
