In life, various applications such as Internet social networking, audio and video, e-commerce, scientific experiments, and so on are constantly producing tens of millions, hundreds of millions, or even tens of billions of small files. The understanding of massive small files is usually defined by quantification. Files with a size of less than 1MB are called small files, and those with a number of millions or more are called lots of small files . Difficulties in small file transfer The transfer of massive small files is quite different from that of large files. The performance consumption and bottleneck of transferring large files are attributed to bandwidth, while the transfer of massive small files is different. Because the filehandle needs to be opened/closed frequently in the transfer of massive small files, but there is very little content to read and write after the files are opened, the bottleneck of the transfer of massive small files lies in IO performance. Mass small file transfer is a recognized problem in scientific and technological circles, and many technicians have been working hard for it. The following are two solutions given by Raysync, the leading brand of enterprise-level large file transfer. Breakthrough point of massive small file transfer solution 1. I/O read-write optimization technology I/O Input/Output, Raysync utilizes excellent I/O read-write optimization technology , supports up to 5000 read-write capacity per second, provides efficient support for massive small files, and provides high-speed transfer support services for massive files. 2. High-speed Transfer Protocol Raysync has independently developed high-speed transfer protocol, which breaks through the transfer defects of traditional FTP and HTTP and can effectively improve the existing transfer efficiency, reaching more than 100 times the traditional data transfer efficiency, ensuring the high-frequency and extremely fast transfer of massive small file data.

In the Internet age, data transfer and file synchronization are the basic tasks of daily business development of enterprises. And with more and more branches of enterprises, the amount of data is getting larger and larger, and problems such as the loss and leakage of enterprise core data in the process of file transfer and synchronization begin to stand out. How to make the files of each branch transfer quickly and synchronize the files between multiple servers and multiple data centers is a problem that enterprises need to pay attention to. At present, there are many software tools for file transfer and synchronization on the market, but there may be some problems: 1. Unsecure Some software may be constrained by the network environment, the distance of transmission or synchronization, etc. Files are easy to be lost and damaged during transfer or synchronization, and data loss will cause a serious blow to enterprises. 2. Troublesome Many software or tools have a single function and only support one-to-one file data synchronization or transfer application mode. Or the deployment process is complicated, and manual troubleshooting is needed after errors, which wastes time and labor cost. 3. Unreliable When millions of small files are synchronized or transmitted, packet loss may occur, resulting in incomplete and inaccurate transmitted or synchronized files. Raysync is definitely the best assistance of file transfer and file sychronization. First of all, Raysync can guarantee data security, and the bank standard AES-256 encryption ensures the data transfer compliance and security. Secondly, the Raysync self-developed transfer protocol can increase the transfer speed by 100 times in one second. Moreover, the enhanced file synchronization function of Raysync has established a data synchronization solution that meets the business scenarios of enterprise users through the core technologies independently developed such as high-speed engine technology and high-speed transfer protocol technology. Finally, regardless of distance and network conditions, the mechanism of Raysync file breakpoint resume and error automatic retransfer ensures automatic retransfer even if the transfer is interrupted due to unpredictable circumstances in the process of transfer, thus ensuring the integrity and accuracy of transfer results.

With the explosive growth of enterprise data, not only is the amount of data increasing, but the size of a single file is also increasing, including a 1GB picture, a 3GB video, a 12GB design drawing, and even hundreds of large files. These files are important business data of enterprises and organizations. When these data are collected, they will form a complete business map of enterprises, which is of great significance. The challenge faced by large file transfer: The transfer tools that people usually used to transfer the small files will be inconvenienced in transferring the number of large files. If the file is larger, people often think of using express hard disk to transfer it, but it usually takes three or four days to express hard disk, and there is also the risk of express loss. These methods can not meet the needs of enterprises to obtain large files in time. - The file volume is large, and the data transfer is slow, which seriously slows down the business progress. - The security of the data can't be guaranteed with the traditional file transfer protocol, the conditions like data leakage or damage is occurs frequently. - The transfer mode is too complicated, which consumes too much time and labor cost. Relied on the self-developed transfer protocol, Raysync transfers the data at full line speed, while protecting the security of all the data. - Adopting the intelligent segmentation technology of super-large files, the transfer speed of large files can also be guaranteed. - Supports the advanced mechainisms like breakpoint resume and error retransmission to ensure complete and accurate of data transfer. - The bank standard AES-256 encryption protects the security of the data. - Supports two-way file synchronization between client and server, and bid farewell to the troublesome of manual copying. It's time to say goodbye to the traditional ways. With Raysync, it's never been so easier to transfer large files at such a high speed than ever.

Case study: An intelligent technology company urgently needs to transfer 8TB of R&D data to the Swiss branch, and there is no urgent need for big data transfer at ordinary times. Customer demand analysis: 1. "Urgent" demand: R&D data needs to be distributed to the Swiss branch as soon as possible and put into production immediately. If you mail the hard disk or the traditional FTP transfer method, you can't meet the customer's demand for the timely delivery of the data. 2. Cost control requirements: The companies’ big data transfer has the characteristics of low frequency. The company has not set enough budget for the big data transfer project. After understanding the data transfer solutions in the market, it is found that a set of software needs to cost hundreds of thousands, which will cause serious waste of resources and financial resources, which is inconsistent with the needs of the company. 3. Flexible requirements: Just like the urgent transfer of 8TB files to Switzerland this time, we can't predict whether the next large file transfer task will also be affected by unexpected factors, that is, the transfer software pay-as-you-go plan is the best choice for enterprises. 4. Data security requirements: Production R&D data is the lifeblood of enterprise production and operation, and its importance is self-evident. In the process of transfer, due to poor network environment and long transfer distance, it may lead to low transfer efficiency, and file transfer security loopholes are more likely to occur. The leakage of R&D data will bring a devastating blow to enterprises. Considering the need to transmit enterprise R&D data overseas, the company has high requirements for the security of the transfer process. 5. Requirements for easy-to-use: The company's big data transfer frequency is low, the interface is simple, the operation is simple, and the convenient and fast transfer software is deployed, which will greatly reduce the time cost for employees to learn to use the software, and the work of data uploading and downloading will get started faster. The Raysync server is deployed at the Nanjing headquarters of the company, and the team members of the Swiss branch can log in to Raysync through IP address and port number, so as to easily upload and download the production R&D data. Compared with the traditional FTP transfer, the timeliness of Raysync transfer is improved by 96%.

In the Internet age, speed determines efficiency. In the process of enterprise production, it is necessary to exchange and carry information and data, and then file transfer is necessary. All aspects of the industry involve the transmission of large files. For example, the film and television industry needs to transmit video materials every day, and video data as small as tens of megabytes and as many as several tons should be transmitted from the shooting place to the video center. Or meteorological observation points around the meteorological industry need to make meteorological observations in real-time and summarize the data to the Meteorological Bureau immediately and effectively, so as to issue accurate weather forecasts. Faced with such a huge amount of data, how can enterprises transfer large files safely, stably and efficiently, then the large file transfer tool is essential for enterprises. Small file transfer can be carried out by using network sharing tools such as WeChat, email, etc. Although the point-to-point transfer is convenient to use, there is a limit to file size, and the speed is sometimes slow according to the network environment. But it is a convenient choice for individual users to transfer small files. Large file transfer using Filezilla, network disk, and so on is stable and supports breakpoint continuous transfer. However, the speed of large file transfer is extremely slow, the packet loss rate is high, the transfer reliability is poor, and the speed of transnational transfer is particularly low. It is inconvenient to use the network disk, and it is necessary to upload the file to the terminal before downloading it. In addition, for large files, it is also possible to send a large number of files to their destinations. However, unpredictable problems such as hard disk damage and express delivery delay easily occur during transportation, and the real-time performance cannot be achieved. Speed determines efficiency, time determines money. Nowadays, big data is very important for enterprises, and huge data must be transmitted quickly in order to grasp the information in the hands of enterprises in real-time. Realizing the fast transfer of large files can improve work efficiency, and make enterprises one step ahead of others. According to the needs of the film and television production industry, Raysync Transmission has launched a solution for the film and television production industry based on ultra-high-speed transfer protocol. Thoroughly overcome the inherent bottleneck of traditional data transfer methods, such as FTP and HTTP, and provide the maximum transfer speed that is not affected by network conditions and transfer distance for video transfer, video upload, video return, and other audio-visual content transfer, thus providing the real high-performance data transfer for the film and television production industry.

We have been talking about data integration, but that doesn't mean we all understand it. It seems simple to talk about data integration, but when we explain the definition, we will find many different explanations. In order to avoid obscuring the concept of data integration, today we will start from the common data integration types in 5, and have a deep understanding of data integration. The definition of data integration According to the definition given by China Science Communication, data integration is to logically or physically concentrate data with different sources, formats, and characteristics, so as to provide comprehensive data sharing for enterprises and make data more valuable. IBM pointed out that "data integration is the integration of technology and business processes, which realizes the integration of data from different sources into meaningful and valuable information." 1 Data Consolidation ETL pulls data from sources, transforms it into an understandable format, and then transfers it to another database or data warehouse. The ETL process cleans, filters, and transforms data, and then applies business rules before data populates the new source. 2 Data Dissemination Data dissenminationj is the use of applications to copy data from one location to another. It is event-driven and can be done synchronously or asynchronously. Most synchronous data propagation supports two-way data exchange between source and target. Enterprise application integration and enterprise data replication technologies support data dissemination. EAI integrates application systems for the exchange of messages and transactions. It is often used for real-time business transaction processing. The integration platform as a service is a modern approach to EAI integration. EDR typically transfers large amounts of data between databases, instead of applications. base triggers and logs are used to capture and disseminate data changes between the source and remote databases. 3 Data Virtualization Data virtualization is an inclusive term used to describe all data management methods, which allow applications to retrieve and manage data without technical details related to data, such as its format or physical location. Data can be viewed in one place, but cannot be stored in that place. Data virtualization can retrieve and interpret data, but it doesn't need a uniform format or a single access point. 4 Data Federation Technically, Federation is a form of data virtualization. It uses virtual database and creates general data model for heterogeneous data from different systems. Data is aggregated and can be viewed from a single access point. Enterprise Information Integration is a technology that supports data union. It uses abstract data to provide a unified view of data from different sources, and then presents or analyzes data in a new way through applications. In the face of the high cost of data integration or excessive security and compliance problems, virtualization and federated authentication are good solutions. 5 Data warehouse Data warehouse is a strategic collection that provides all types of data support for the decision-making process at all levels of enterprises. It is a single data store created for analytical reporting and decision support purposes. Provide guidance for business process improvement, monitoring time, cost, quality and control for enterprises that need business intelligence. The data warehouse is integrated, and the data in the data warehouse comes from scattered operational data. The required data can be extracted from the original data, processed and integrated, and unified and integrated before entering the data warehouse. We will find that no matter which integration type is mentioned above, it reflects a key point. Data integration needs to achieve integration through data exchange between applications. Since data exchange and transfer are involved, it is suggested that you can enter two systems, namely Raysync large file transfer system and SDK integration system, and actually experience several stages of integration work.
