How to Transfer Files Securely under the Complicated Network Environment?
The 21st century is an era of rapid development of data and information. Mobile Internet, Internet of Things, social networks, e-commerce and so on have greatly expanded the boundaries and application scope of the Internet. Various data are expanding rapidly, and the whole society has entered the era of big data. However, big data is a double-edged sword. While the country and enterprises vigorously promote the innovative application and benefit of big data, criminals and the "black industry chain" are also stealing and selling information wantonly on the road of data transfer. "Streaking" of Core Information in Big Data Environment Data and information contain the great value, and criminals are pervasive, collecting and selling all kinds of data and information, which leads to the disclosure of personal privacy, enterprise core data, and even state secrets on the Internet. As the basis of data interaction, data transfer and file transfer are the hardest-hit areas of data leakage. Common data transfer risk sources are as follows: 1. The safety risk coefficient of the big data transfer process is high; 2. The management of enterprise data transfer is not strict; 3. The encryption link is too weak; 4. The file transfer tool used is unsafe.

How to Solve the Problem of Cross-border File Transfer in the Global Layout of Enterprises?
In the first half of 2022 enterprises are facing a "great shock" in the global layout, and international trade, cross-border investment, and population mobility have all experienced an unprecedented sudden drop trend. In the complex domestic and international environment, the offline business operation of enterprises is blocked, the online business is surging, and the problem of slow cross-border file transfer is exposed again. Three major problems, such as the rapid increase of data volume, inefficient transfer of large files, and unstable cross-border transfer, are forcing modern enterprises to enhance their digital operation capability. In dealing with the problem of cross-border file transfer, the key point is that due to the influence of network physical conditions, traditional FTP, mail, and instant messaging tools will have high latency, high packet loss rate, and insecure data transfer stability and file transfer quality. If modern enterprises want to make a global layout, they must face the problem of the cross-border file transfer. In view of the above problems, we analyze the solution of cross-border file transfer with Raysync. The obstacles of the cross-border file transfer: 1. Speed Due to the influence of network physical conditions, the high latency and high packet loss rate of transnational WAN seriously affect the stability of data transfer. Especially in the face of increasing data volume, it aggravates the slow transfer speed and low transfer efficiency caused by network congestion, latency, and packet loss, but ordinary enterprises often do not have this technical solution ability. 2. Security There are certain security risks in cross-border file transfer tools and transfer processes. For example, FTP, a free file transfer tool, in not encrypted, and FTP script and batch files keep user ID and password publicly, which is vulnerable to hacker attacks. In the process of transfer, the hard disk transfer is at risk of damage and loss, while the non-compliant file transfer software has an unsafe connection, so it is easy to leak and steal the transmitted data in the process of data transfer. 3. Cost In order to obtain professional technical support and high-quality and reliable service, some large enterprises will choose international special lines provided by telecom operators or secondary operators. However, this method is not only long in the application period, but also extremely expensive, which is unbearable for SMEs. More importantly, international private lines also have congestion problems during international time, and their transfer performance will still be greatly affected by high concurrency. If you want to make a global layout, how can modern enterprises solve the problem of GB or even TB file data and provide it to overseas customers and global branches efficiently and stably? How can improve file sharing efficiency? 1. Solve the technical problems from the root Transport layer protocols TCP and UDP, UDP has a great advantage in speed. Based on UDP transfer performance, Raysync high-speed transfer protocol independently developed by Raysync breaks through the defects of traditional FTP and HTTP transfer, and the transfer rate is increased by 100X and the bandwidth utilization rate is increased to 96%. Intelligently accelerate the transfer in the whole process, avoid the high packet loss rate caused by network latency, greatly accelerate the efficiency of file outgoing, and the multi-dimensional transfer mode meets the extremely fast transfer requirements of TB-level large files and massive small files. 2. Bank standard encryption protection Raysync is based on SSL encryption transfer protocol, adopts AES-256 encryption technology of international top financial level, and has built-in CVE vulnerability scanning, which adds multiple defense walls for data information, effectively resists external attacks, ensures the privacy of the transfer process, and ensures the integrity and safety of file data transfer. 3. The file verification mechanism is stable Breakpoint resume and automatic retransmission mechanism are adopted in the whole process, and multiple file verification mechanisms are built in to ensure the integrity and accuracy of transfer results and ensure stable and reliable transfer efficiency in ultra-remote and weak network environment. 4. Clarify the demand control costs Only when the capital investment is directly proportional to the functional requirements can the input cost be maximized. For the file transfer requirements such as single large file transfer, transnational file transfer, massive small file transfer, P2P accelerated transfer, object storage solution, or the functional requirements such as file accelerated transfer, file outgoing, file management, etc., a set of mature solutions for Raysync has three matching schemes. For enterprises and teams, it is an effective way to control costs. In response to the upstream and downstream integration of business and accelerating the globalization of enterprises, the high-speed large file transfer solution provided by Raysync can drive the high-speed transfer of global data and enable enterprises to respond quickly in the fierce industry competition.
How to Transfer Large Files and a Large Number of Small Files Faster in Cross-border File Transfer?
There are many documents with complex and diverse formats, how can large files be transmitted at the fastest speed? Transfer large files directly or split into multiple small files? Let's look at a set of test data first: In the same test environment, we transfer 10GB large files and 100,000 small files from Beijing Alibaba Cloud to New York Alibaba Cloud via FileZilla FTP. The difficulty of large file transfer is the large data volume, and the difficulty of mass small files is a large number of files. Using traditional file transfer tools for transfer, no matter which one is transmitted first, it will bring great pressure to the server in the process of file transfer, and the transfer efficiency is definitely not ideal. The cross-border transfer must face the ultra-long distance and weak network environment. The high latency and high packet loss rate caused by network problems can directly affect the efficiency of the file transfer. In the same test environment, let's try it with a professional file transfer tool from Beijing Alibaba Cloud to New York Alibaba Cloud. The transfer data shows that in response to cross-border file transfer, 10GB large files need to be transmitted for 34 hours. After using professional file transfer tools, the speed is reduced to 7 minutes and 30 seconds, and the efficiency is improved by 272 times; In the transfer of 100,000 mass small files, the transfer time is reduced from 168 hours to 1 minute and 50 seconds, and the transfer timeliness is improved by 5522 times. For the problems of large file transfer, massive small file transfer, cross-border file transfer, cross-border file transfer, file sharing, file synchronization, and point-to-point transfer, experts in large file transfer solutions can seek help from Raysync.

How Does the File Acceleration Transfer Solution Improve Work Efficiency?
Many organizations rely on transferring large files from the field or between international offices. Operating through Internet links poses challenges to many standard applications: their performance is poor and transfer may fail. A common example cited by accelerated file transfer application vendors is the file transfer protocol, also known as FTP. Of course, FTP will encounter problems when running on poor quality networks, which have high error rates or long latency related to international and satellite links. In order to improve the efficiency of file transfer, AFT suppliers provide their own applications instead of FTP, thus forcing customers to adopt this AFT technology and integrate it into their existing workflow. Whether FTP or any other application using the basic TCP protocol, the problem is not the application, but the network. FTP can really perform well through high-quality links, so why replace applications to solve network problems? The key to fast file transfer is enough bandwidth and error-free connection. Raysync transfer protocol has been independently developed by Raysync, which is dedicated to meeting the data transfer needs of internal or external partners of enterprises, providing efficient and controllable accelerated transfer of large files, ultra-long-distance, transnational network data transfer, safe outgoing of file assets, file management and organization authority management, supporting local deployment and cloud services, and providing enterprises with safe, stable, efficient and convenient technical support and services for large file interaction. 1. Fast speed The transfer speed is hundreds of times faster than FTP and HTTP, which runs full of bandwidth to the maximum extent and does not affect other network traffic. 2. High efficiency Mass high-speed file transfer softwares is 6000 times faster than FileZilla in the same network environment. 3. Transfer is unlimited Cross-regional and transnational big data replication, migration or archiving can transfer at least 100TB of data every day. Raysync provides self-controllable, secure, and private multi-industry data transfer solutions, and helps customers build information channels and integrate data resources.
Breaking Shadow IT and Solving Enterprise Application Compliance Problems
What's Shadow IT? Gartner analyst Simon Mingay wrote in a research report that Shadow IT in a broad sense includes "investment in the acquisition, development and/or operation of IT solutions outside the formal control of formal IT organizations". To put IT simply, Shadow IT refers to a department or individual who uses IT-related hardware or software without knowing the IT or security group in the organization. In reality, employees in general enterprises rely on software that has not been approved by IT departments. Business departments bypass IT departments and use applications on the cloud to complete their work efficiently and quickly. These are also called "shadow IT". Although "shadow IT" and "business value" doesn't sound directly related, using shadow IT is quite simple and direct. But when shadow IT was exposed, IT revealed many security vulnerabilities to IT departments. Enterprise employees can easily bypass the IT team's approval, but they cannot check the reliability and security of the selected application in depth. Employees unconsciously input important enterprise data into unauthorized cloud services, which makes enterprise data security a gamble directly. In fact, nearly 80% of employees in general enterprises rely on this software that has not been approved by IT departments. Faced with this situation, what should IT leaders do if they find that these unsafe applications are being used by employees or are sharing sensitive information? It's obvious that it's natural to react quickly and demand that these applications be stopped immediately and that employees who violate the company's data security regulations be punished. However, the value gained by IT leaders from the discovery of Shadow IT is equally important for future IT decisions. What is the problem with Shadow IT? If IT executives find that employees are using free file sharing applications, the next step is to find out why employees use them. For what reason do so many employees bypass FTP and other systems and secretly use these applications for file sharing? Only by breaking the root cause of Shadow IT entering the enterprise can we improve the current situation of the enterprise and truly protect the data security of the enterprise. It's easy to find out that many employees express their weakness in the processing efficiency of existing enterprise application systems. FTP is time-consuming and complex, and email is limited by attachment volume, so professional software procurement costs are high. The huge amount of data and the impatient urging of customers make them need a fast way to transfer files. Although the situation of each enterprise is different, fundamentally, the biggest reason for employees to use these file transfer software is that they can handle their work at any time and anywhere with a low cost or even zero cost. Breaking Shadow IT and Solving Enterprise Application Compliance Problems Recognizing the above problems, we will find that it is not enough to order employees to stop using unsafe file sharing applications. No matter how hard IT leaders try to control the organization's data, employees can choose unsafe solutions. Enterprises can choose compliance solutions such as Raysync. The goal of Raysync is to help enterprises and IT departments solve the normative problems of file sharing and provide easy-to-use and high-speed file transmission solutions for enterprise employees to improve office efficiency.

What Should You Know About Big Data?
A large amount of big data is opening the era of data-driven solutions that will drive the development of communication networks. Current networks are usually designed based on static end-to-end design principles, and their complexity has increased dramatically in the past few decades, which hinders the effective and intelligent provision of big data. Big data networking and big data analysis in network applications both pose huge challenges to the industry and academic researchers. Small devices continuously generate data, which is processed, cached, analyzed, and finally stored in network storage , edge servers, or the cloud. Through them, users can effectively and safely discover and obtain big data for various purposes. Intelligent network technology should be designed to effectively support the distribution, processing, and sharing of such big data. On the other hand, critical applications such as the Industrial Internet of Things, connected vehicles, network monitoring/security/management, etc. require fast mechanisms to analyze a large number of events in real-time, as well as offline analysis of a large amount of historical event data. These applications show strong demands to make network decisions intelligent and automated. In addition, the big data analysis techniques used to extract features and analyze large amounts of data places a heavy burden on the network, so smart and scalable methods must be conceived to make them practical. Some issues related to big data intelligent networking and network big data analysis. Potential topics include but are not limited to: 1. Big data network architecture 2. Machine learning, data mining, and big data analysis in the network 3. Information-centric big data networking 4. Software-defined networking and network function virtualization for big data 5. The edge of big data, blur, and mobile edge computing 6. Security, trust, and privacy of big data networks 7. 5G and future mobile networks realize big data sharing 8.

The difference between on-premise file sharing and cloud transfer
When choosing a file transfer solution, enterprises may face the problem of choosing a on-premise file sharing solution or a cloud-based file transfer solution. How to distinguish between on-premise deployment and cloud? Let's have a look! What is on-premise file sharing?  Deploying file transfer software locally means that the file transfer service is deployed on the enterprise's own server, and the local storage data is completely owned by the enterprise itself. On-premise file sharing means that enterprises have complete data autonomy. For users who value the privacy of corporate files, it is more suitable to choose localized deployment of file services. In addition, on-premise means that services can be extended on the enterprise's own IT architecture, with more options. For example, you can customize the access login page to promote your brand, etc. What is cloud transfer? As its name implies, cloud-based file sharing is a method of file transfer through the cloud. Companies will employ cloud-based third-party file-sharing platforms where data is hosted on virtual servers. Companies can choose to use cloud-based servers hosted by third-party providers to access their information. The difference between on-premise file sharing and cloud transfer For enterprises, choosing a on-premise file sharing solution means having full control over file assets. Businesses can deploy the software on local servers, or they can choose to deploy it on third-party servers. In terms of file storage, enterprises can choose to store files locally or configure third-party storage. Therefore, when performing file transfer and synchronization services, the transfer solution provider will not know what files you transfer and who you transfer them to. This is very beneficial for enterprises. This means that enterprises can enjoy high-quality file transfer services, but their own file assets will not be known by service providers. If your business is looking for a fast, reliable, and secure file on-premise file sharing solution service, Raysync is just what you need. Raysync file transfer service supports on-premise and public cloud deployment. Enterprises can deploy servers according to their own needs. At the same time, Raysync will not know your files and data. In addition, as a high-speed large file transfer solution for enterprise users, Raysync also supports SDK, HTTP API, command line, network proxy and other integration methods to quickly and seamlessly integrate with existing enterprise systems. Conclusion When choosing a file transfer service, it is necessary to consider the company's own factors. Individuals may be more inclined to cloud transfer software, while companies with a large demand for file transfer will choose local deployment services and then configure storage independently. Because this kind of software does not read or store any data of your company, enterprises in need can deploy it on their own servers, and the maintenance cost is very low. If you need a detailed solution, maybe Raysync could be a nice choice!
Which is Faster between TCP and UDP?
The TCP/IP protocol set includes hypertext transfer protocol , text transfer protocol , remote login protocol , internet protocol , internet control message protocol , etc. In the TCP/IP protocol family, there are two distinct transport protocols: TCP and UDP In this article, we'll continue with what TCP and UDP are, the difference between the two, and which protocol is faster! If you are interested, keep reading! What is TCP? TCP stands for Transmission Control Protocol, a transport layer protocol that allows packets of data to be sent from one location to another. It is a connection-oriented transfer protocol, that is to say, before sending and receiving data, a reliable connection must be established with the other party. A TCP connection must go through three "dialogues" before it can be established. It is a solid protocol. Because, the receiver will always provide the sender with an acknowledgement message about the data packet, either positive or negative, the sender can always know whether the data packet has reached its destination or needs to be resent.  Whenever a data packet is received over TCP, the receiver sends an acknowledgement to the sender. In case of failure, it requests a re-transmission. It guarantees that data reaches its destination and arrives in the same order as it was sent. It has a built-in error checking and recovery system responsible for providing end-to-end communication. TCP also provides access to flow control and quality of service. What is UDP?  UDP stands for User Datagram Protocol. Which is the most basic transport layer communication protocol of the TCP/IP protocol suite. It uses minimal communication mechanisms. In UDP, the receiver does not generate an acknowledgement of a packet, nor does the sender wait for an acknowledgement of a packet. Since data transmission does not establish a connection when using UDP transfer protocol, there is no need to maintain connection status, including sending and receiving status, so one server can transfer the same message to multiple clients at the same time. At the sending end, the speed at which UDP transmits data is only limited by the speed at which the application generates data, the capabilities of the computer, and the transmission bandwidth; Read a message segment. UDP transfer protocol does not need to perform a three-way handshake to establish a connection before sending data like TCP transfer protocol. If you want to send data, you can start sending. And it is only a porter of the data message, and will not perform any splitting and splicing operations on the data message. Because TCP needs to establish a connection, and ensure reliability and order, it is time-consuming. That's why video streaming, broadcast TV, online multimedia games, etc. choose to use UDP. The Difference between TCP and UDP  1.TCP is a connection-oriented protocol, UDP is a connectionless protocol. TCP uses a three-way handshake to establish a connection before sending data, and UDP does not need to establish a connection before sending data. 2. TCP is reliable, UDP is not reliable. TCP lost packets will be automatically retransmitted, UDP will not . 3. TCP is ordered, UDP is out of order. Messages may be out of order during transmission, messages sent last may arrive first, TCP will reorder them, UDP will not. 4. TCP file transfer protocol, UDP file transfer protocol. Because TCP needs to establish a connection, and ensure reliability and order, it is time-consuming. Maybe a graph is more clearly!   TCP UDP Speed Slower Faster Connection Connection-oriented Connectionless Acknowledgement Acknowledgement sent by the recipient No acknowledgement is sent Reliability High Low Transfer method Stream Individual packets Applications File transfer, email, web browsing Video conferencing, gaming, broadcasts Congestion control Yes No Summary of TCP & UDP TCP is a connection-oriented, reliable, ordered, and slow protocol; UDP is a connectionless, unreliable, unordered, and fast protocol. TCP overhead is larger than UDP, the TCP header needs 20 bytes, and the UDP header only needs 8 bytes. Overall, UDP is a faster, simpler, and more efficient protocol. But TCP allows the retransmission of lost packets. Which is Faster between TCP and UDP? UDP is a connectionless protocol, while TCP is a connection-oriented protocol. TCP is slower than UDP, which is one of the main differences between the two protocols. TCP is slow and UDP is fast. Bonus Tips: Improve Your File Transfer Speed In the MFT solution, Raysync uses a self-developed high-speed transfer protocol, which not only supports error retransmission, and resumed transmission, but also supports file block verification. It enables files to be transferred at the highest speed under the user's bandwidth, while also ensuring 100% correctness of large file transfers. In addition, Raysync also supports two high-speed file transfer protocols, UDP and TCP. Enterprises can choose from four transfer modes: 1. Automatically select UDP and TCP, and can be set to automatically switch to TCP when the delay is lower than a certain millisecond. 2. Only use UDP. 3. Only use TCP. 4. Choose UDP first, and automatically switch to TCP when UDP fails to communicate. If you think Raysync could be a good fit for your organization, schedule a demo or learn more here. Conclusion Both TCP and UDP have their uses. If the main concern is the reliability and order of data reception, you will prefer to use TCP. On the other hand, if speed is the main concern and the corruption or loss of some packets is not that important, choose UDP. So as you can see, you have to compromise between reliability and speed. If one of them is raised, the other will be lowered due to the preceding constraints. TCP is used for HTTPS , HTTP , SMTP , FTP , and more. UDP is used for video streaming, video telephony, Voice over IP , DNS , and more.
