The world now has a mature system of international division of labor and cooperation. Taking film production as an example, the shooting team, publicity team, and post-production team may be distributed in different cities or even different countries. How to ensure timely and fast file transfer and collaboration between these teams during the production and promotion cycle is a challenge. What are the Difficulties of Worldwide File Transfer? In the process of international file transfer, many difficulties are often faced. Such as file transfer timeliness, accuracy, security and so on. It can be said that any point is critical to the security of enterprise file transfer and the smooth progress of the project. First, obviously the biggest challenge is the transmission distance. We all know that the greater the geographical distance, the more likely it is to be limited by various network conditions. In the past, FTP used to be an important way for enterprises to transfer files, but soon, FTP was gradually abandoned by enterprises due to high latency and high packet loss rate. In cross-border file transfer, how to ensure the complete and secure transfer of files in the case of ultra-long distance is an important assessment point for enterprises when choosing file transfer software. There is also the stability of cross-border file transfers. We all know that enterprises need to transfer a large number of files every day. If the file transfer is unstable, it will cause inaccurate and unpunctual file transfer, which is not good for the progress of the project. Then, when transferring files across countries, it is also affected by the file size. Some file transfer software works very well at transferring mega files, but once the file size exceeds terabytes or even petabytes, it is difficult to guarantee a complete and fast file transfer. For companies in the film and media industry, sometimes the original file size of just one shot may exceed 20TB. Such a huge file size, coupled with the network conditions for the long-distance cross-border transfer, is likely to make subsequent publicity and production teams in trouble. And in the security performance of cross-border file transfer. Due to the long transmission distance and the uncertainty of the contacted personnel, it is difficult to guarantee the security and confidentiality of the data. For enterprises, if the transmission security of files cannot be guaranteed, the information of the enterprise will be exposed to the danger of leakage at any time, which is detrimental to the protection of intellectual property rights.

The security performance of long-distance transmission requires various guarantees. For example, file encrypted transmission, user rights management, enterprise file intellectual property protection, etc. At the same time, the international file transfer software itself needs to pass multiple security certifications. 2. How to choose a worldwide file transfer software? A qualified international file transfer software will provide multiple levels of security. In terms of the security of the software itself, passing ISO27001 and TPN certification is a good security guarantee, which means that both the software itself and the software service provider have complete security and confidentiality guarantees. In terms of file transfer, cross-border file transfer software needs to provide the fastest possible transfer speed under the user's network conditions, while being able to provide scalable large file transfer capabilities for different levels of files. Conclusion In the above introduction, we can know how to measure the cross-border file transfer capability of a file transfer software. However, the final file transfer selection requires enterprises to choose according to actual business needs. For example, the design industry can consider software with online preview of CAD files, while the media industry can choose software with rich file collaboration and synchronization capabilities. Choosing the right file transfer software is very beneficial to the company's multinational business development.

Latency is a key factor to measure the network condition. Every network is subject to latency. Network latency refers to the round-trip time for files or data packets to be sent from the user’s computer to the web server. In a word, latency is the total time for data to be transferred from one side of the computer to the other. What is High Latency? Network high latency means the time send to other computers is high, and it often comes with pack loss when transferring massive files. Latency is measured in milliseconds, abbreviated "ms", and can be measured using your computer's ping command. Since network traffic is dynamically changing in real-time, network latency is also changing over time . The smaller the network delay and the jitter of the network delay, the better the quality of the network. Generally speaking, the network delay is between tens to hundreds of milliseconds. The main factors that affect the network delay are the number of hops on the route and the traffic of the network. Because each route forwarding takes time, the more routing hops, the greater the network delay; The greater the network traffic, the longer the queuing time between switches and routers, and the greater the network delay. The Difference between Latency and Bandwidth What is bandwidth? Bandwidth is measured in Mbps or megabits per second and refers to the amount of data that can be transferred in a unit of time . Bandwidth actually refers to the width of the data pipeline, not the speed of data transfer. When you hear someone say "My internet speed is 100Mbps" or something like that, they're actually referring to the bandwidth capacity of their internet service, not the speed. The speed of the network is actually the result of bandwidth and latency. Here is an example to help you accurately understand the between high latency and bandwidth. Transfer files with good bandwidth and poor latency The file transfer software takes a long time to process the file, but once the file processing is finished and the transfer task starts, the file can be transferred at a very high speed. Transfer files with good latency and poor bandwidth The file transfer software can process the file immediately, but the transfer speed is slow. Why High Latency？ a. Too many routing hops between the device and the server Although the propagation time of light and electricity in the physical medium is almost negligible, during network file transfer, if there is too much routing and forwarding processing between the device and the server, the network delay will be obvious. b. Insufficient network bandwidth If the device and the server are directly connected through one router, but the bandwidth is only 20Kbps, and there are multiple applications that need to transfer data volume far exceeding the bandwidth of 300Kbps, a large amount of data will be lost, which will manifest as a response delay. c. Insufficient processing bandwidth If the device and the server are directly connected through a router, and the bandwidth is sufficient, but the processing capacity of the server is insufficient, the response delay will also be caused. Why do You Need to Address High Latency? In today's increasingly popular international cooperation and social division of labor, enterprises need to transfer and synchronize a large number of files every day. In addition, data transfer has become a part of their daily work. Traditional file transfer methods, such as FTP, web page transfer, etc., have slow transfer speeds and unreliable data delivery when transferring large files or transferring massive small files. The inefficiency of file transfer caused by high latency greatly affects the workflow of enterprises. Also, in international file transfers, the farther the data is from the sender of the file and the receiver of the file, the higher the latency, resulting in an excessively long time remaining while the file is being transferred. Files transferred through high-latency environments not only result in slow transfers, but also unreliable transfers, such as packet loss or source file corruption. For media industry users, the consequences of high-latency transfer are unacceptable. When media files such as videos are transmitted at high speed over long distances, the size of these files often reaches the TB level. Due to the large round-trip time under high latency, the remaining time for the transmission of these large files will be too long, which will seriously affect the delivery time of media files. How to Solve the Problem of High Latency？ How to make your large file uploads stable and fast? Raysync adopts two ways. The first is block upload technology. This technology will split large files to be uploaded into chunks, and verify and transfer them separately. After the upload is completed, the interface will be called to form a complete object. This method perfectly solves the problem of large files, especially large media files, being transferred over long distances. The resume from breakpoint assigns a unique task identifier to each upload behaviour. In addition to the serial number, each chunk will also carry the task identifier when uploading. Suppose the file transfer needs to be continued after the file transfer is suspended for some reason. In that case, the server will check the existing task ID and upload directly from the position where the transfer was disconnected last time. Raysync maximizes the transfer speed in a variety of shared and private network environments and is not limited by network delays and packet loss. Even over long distances, the file transfer time and quality can still be guaranteed with Raysync. Conclusion If you need to transfer files at high speed in a high latency environment, Raysync will transfer your files 100% correctly at ultra-high speed. FREE Trial contact: support@raysync.io

AFTP is a file transfer protocol developed by JSCAPE. AFTP is meant to accelerate file transfers over high-speed networks that are unable to utilize network output thanks to high latency and packet loss. beneath these conditions, AFTP will accelerate file transfers up to 100 times quicker than FTP and alternative file transfer protocols. How Does Accelerated File Transfer Protocol Work? Popular file transfer protocols like FTP/S, SFTP associate degreed HTTP/S depend upon an underlying protocol named TCP. The matter with TCP is that as network conditions like latency and packet loss increase, network output is considerably reduced. This is often for the most part to thanks to the algorithmic program accustomed to guaranteeing TCP reliableness. TCP uses a Window algorithmic program that reduces output as latency and packet loss increase. The result's that file transfer protocols supported TCP are typically unable to utilize information measure accessible, in result greatly increasing the quantity of your time required to transfer a file. the results of this are typically seen in satellite, continental, and water file transfers. AFTP solves this drawback by dynamic the manner file transfers are performed. Instead of relying completely on TCP, AFTP has 2 communications channels employing a combination of TCP and UDP protocols. The primary channel, known as the management channel, uses TCP and is chargeable for tasks like user authentication, file management, and coordinating file transfers. The second channel, known as the info channel, uses UDP and is chargeable for transferring file information. Unlike TCP, UDP doesn't suffer an equivalent level of output reduction in comparison to TCP beneath similar network conditions. AFTP is ready to take advantage of this by sending a majority of information over UDP, therefore providing the best output. AFTP implementations can do reliable file transfers whereas reducing file transfer times by many orders of magnitude in comparison to TCP primarily based file transfer protocols. Will AFTP Work For Me? AFTP provides the best performance gains once utilized in high information measure networks that suffer from high latency . as an example, a file transfer between Tokyo and Los Angeles over a 45Mbps association is probably going to own high latency given the geographical distance between these 2 locations and can enjoy the employment of AFTP. Conversely, a file transfer between 2 hosts on a LAN over a 100Mbps association is unlikely to own high latency or enjoy the employment of AFTP. What Is The Latency? In a network, latency could be alive of the quantity of your time it takes for a packet of information to induce from one network purpose to a different. Latency will be plagued by several variables as well as the distance between points, the number of gateways between points, and therefore the medium used . Latency is usually measured in milliseconds . Example: The latency between Host A in Los Angeles and Host B in Tokyo is two hundred ms. What Is Packet Loss? Packet loss could be a network condition once one or additional packets of information fail to succeed in their supposed destination. Packet loss is measured as a proportion of packets that don't reach their destination, additionally called lost or born packets. Example: The packet loss between Host A in Los Angeles and Host B in Tokyo is one.0%. What Is The Throughput? Throughput is the actual rate of information delivered over a network. The output is usually measured in rate . the output is commonly a fraction of information measure thanks to network conditions like latency and packet loss. Example: The output between Host A in Los Angeles and Host B in Tokyo is 5Mbps. What Is Bandwidth? Bandwidth is that the theoretical most rate of information delivered over a network. Information measure is usually measured in rate . Example: The information measure between Host A in Los Angeles and Host B in Tokyo is 45Mbps. What Is The TCP? TCP could be reliable informatics primarily based network protocol in this all packets are sent so as and if a packet is lost， it'll mechanically decide to resend that packet. What Is UDP? UDP could be a relative to the TCP protocol, each of that is captivated with the underlying informatics stack. Unlike TCP, UDP doesn't need that packets to be sent so as and doesn't mechanically decide to carry lost packets. Retransmission and rearrangement of packets ar the responsibility of the upper-level protocol, during this instance AFTP.

Sending large video files to others is not as simple as you think. Depending on the resolution and length, the size of the video file can quickly exceed the 25MB attachment limit imposed by most major email providers. But this does not mean that there is no way to share large video files. If you want to know more, please keep reading. We will explore the best way to send videos worldwide. How to Send Video via Email? As we mentioned earlier, almost all email providers impose a 25MB size limit on any file that you want to attach to an email. Some services are as low as 10MB. Smartphone videos longer than a few seconds will soon exceed this limit. If you created a recording with professional equipment, then you will not have a chance. But don’t worry. If the file is larger than the 25MB limit and you want to send the video via email, you still have two options: you can create a recorded ZIP file or use the cloud storage service of your email provider. For those who don't know, ZIP files are compressed versions of files. You created the ZIP file at the end and sent it to others. Then, they receive the file and decompress it to restore the video to its original size. Both Windows and macOS have native features that allow you to compress and decompress files, although many third-party options are also provided. To create a ZIP file on Windows, find the file you want to compress, right-click the file, and go to Send to > Compressed folder. To create a ZIP file on macOS, find the file in question, click the right-click button, and select "Compress Project" from the context menu. Of course, if your newly created ZIP file still exceeds 25MB , you will still not be able to send the video via email. You need to use other options instead. How to Use Cloud Storage Services to Send Large Video Files? Most large email services also provide some form of free. You can use storage space to send large video files that exceed the 25MB limit. If Gmail and Outlook detect that the file is too large, they will automatically provide you with the option to upload the video to their respective clouds. Once the file is stored in the cloud, you can attach it to the email in the usual way. Then, the recipient will be prompted to download the video from the cloud instead of from the email server. However, if they wish, they can also watch the video in the cloud without downloading it to the device. Unfortunately, even this method is not without its drawbacks. Most notably, you are still limited by the available space in the cloud storage drive. Google provides you 15GB for free; OneDrive and iCloud only provide 5GB. If you need more, you need to subscribe to a plan that costs a few dollars per month. There is also the problem of confusion. You just need to use a cloud drive to send some videos via email and you will be drowned in unattached files. If you use cloud services to store all your documents, that would be far from ideal. How to Send Large Video Files from iPhone? If you want to watch large videos on your iPhone, you cannot use WhatsApp. The attachment limit on instant messaging applications is 16MB. iMessage is slightly better; the maximum file size is 100MB. What Other Options do You Have? If you want to send a file to another Apple device nearby, the most direct way is to use AirDrop. There is no file size limit, and you don’t need to install any third-party applications—this feature is a native part of the operating system. This is one of the best ways to transfer files between computers.

File synchronization is the process of ensuring that two or more locations contain the same latest files. If you add, change, or delete files from one location, the synchronization process will add, change, or delete the corresponding files in another location. Synchronization can be "two-way" or "one-way". What is One-Way Synchronization and Two-Way Synchronization？ Two-Way Synchronization This synchronization process copies files in both directions to coordinate changes as needed. It is expected that the file will change in both locations. These two positions are considered equivalent. Example: If the file is newer in location A, it will be copied to location B. However, if the file is newer in location B, it will be copied to location A. Similarly, if a file is deleted from location A, the file will be copied. Also deleted from position B, and vice versa. One-Way Synchronization The file can only be changed in one location. To coordinate changes, the synchronization process copies files in only one direction. These two positions are not considered equivalent. Ø NE location is considered the source and the other is considered the target. The file is pushed away from the source to target . It is said that Source has been mirrored to Target. This will create an exact 1:1 copy of all files in the "source to target". Since only new files are changed, this is very useful and effective for backup. Example: If the file is newer in location A , it will be copied to location B . However, if the file in location B is newer, it will not be copied to location A. Similarly, if a file is deleted from location A, it will be deleted from location B. Auto-Sync File synchronization can be run automatically at irregular intervals, ie every 10 minutes, every 2 hours, etc., at scheduled times , in real-time . Detected at startup or shutdown. Common File Synchronization Solutions Synchronization between computers connected to a local network . The computer can be a laptop, desktop, workstation, server. For cross-computer sharing of selected folders, use Windows file sharing and sync use and vice versa. Synchronization between computers connected to the Internet . This requires a VPN tunnel. The computer can be a laptop, desktop, workstation, server. Synchronization between computer and external drives . Synchronization between computer and NAS. The ultimate goal is to ensure that the selected folder on the computer and/or drive has the same latest files. Synchronization between unconnected computers For computers that are not connected to the network, you can use a portable USB drive to synchronize. If the files on the home computer must be synchronized with the files on the computer at work, you can synchronize the PC-1 with a portable USB drive, and then connect the PC-1 with the portable The USB drive is synchronized to achieve synchronization. The drive works normally and performs the same synchronization between the PC-2 and the portable USB drive. At the end of the process, the same latest file will be on both PCs and USB drives, which is useful for data backup.

High-speed file transfer is a complex subject. Not all file transfer software is the same. Fundamentally speaking, all file transfer programs help to transfer information between systems. Certain frameworks or methods are good at high-speed file transfer. Many factors affect the delivery time of files or data: Internet speed, computer specifications, packet loss, and distance. However, the most important bottleneck in today's file transfer software is not necessarily a network problem, but a design problem. In some cases, you need to send important files to customers as soon as possible, but the files are too large to attach. Or, you may come across a cute cat video and want to send it to your friends, but cannot because the connection speed is too slow. These trivial things should not disrupt your work rhythm. Don't worry, because file transfer software can eliminate this inefficiency. What is File Transfer Software? File transfer software is a tool that facilitates data sharing or reception between two or more users with or without an Internet connection. When the data to be transferred is too large or in formats that cannot be read by traditional file sharing methods, sharing or receiving files is a great application. Why Your Business Needs High-Speed File Transfer Software? Savvy business acumen may think about the need for high-speed file sharing software to transfer files. Indeed, even before the Internet boom, data sharing methods still existed. But there have been many changes since then. PC-to-PC file transfer software or PC-to-mobile file transfer via WiFi software has huge benefits, which are vital to your business. • Useful resource-saving The PC's file transfer software can send data faster than blinking an eye with minimal errors. By using the best file transfer software, companies can save a lot of staff's energy and time to save time in delivering critical information.
