What Technology Does Raysync Adopt to Transfer File Cross-border?
Cross-border file transfer and transnational transfer have to face the network transfer environment of ultra-long distance and weak network. If you want to transfer files fast, read on to learn how professional file transfer software Raysync transfers. For Congestion Handling: - More effective congestion judgment and treatment. - The recovery mechanism of packet loss judgment is carried out more accurately and timely. At present, the mainstream congestion judgment is designed based on the network situation data back to twenty years ago, and its basic assumption is that any packet loss reflects the network congestion. This assumption is completely out of line with the modern network situation. Packet loss in modern networks is often not caused by congestion factors. This disconnection leads to the transfer protocol often entering an overly conservative transfer state. The congestion detection algorithm of Raysync transfer protocol automatically collects the existing background transfer information on the path, and accurately judges the actual congestion situation according to the transfer speed, which is neither too conservative nor too radical, and can effectively make full use of the path bandwidth. For Packet Loss: - The standard TCP protocol tells the packet loss from two methods. - The receiving end continuously confirms the number of Dup-ACK. - ACK timeout. When the situation of packet loss always happens, the ACK is needed to judge the timeout and trigger to retransfer. Packet loss in modern networks is often burst, and it is common for multiple data packets to be lost at the same time on a connection. Therefore, standard TCP often relies on time-out to retransmit holes, which often leads to a waiting state of several seconds or even ten seconds, which makes transfer stagnate or even interrupt for a long time. This is one of the main problems affecting the efficiency of standard TCP. Raysync transfer protocol abandons TCP protocol's practice of using transfer message sequence as both transfer byte count and reliable transfer confirmation identifier and designs a brand-new ACK data algorithm. According to the ACK information returned by the transfer receiver, the transfer sender can accurately judge the packet loss and retransfer the data at the first time, instead of relying on the cumulative acknowledgment of multiple acks or the ack timeout timer to trigger the data retransfer, which greatly improves the transfer speed and transfer real-time. Raysync transfer protocol can make full use of large bandwidth network and transmit data at the fastest speed. In the application scenario of mass data distribution, it can help users to complete big data transfer and cross-border file transfer in the least time.

How to Transfer Large Files Quickly? Raysync Provides You a Perfect Solution
With the development of the Internet, it is a very common thing to transfer large and small files in the daily office. If it is a small file, there are many ways to transfer it, and it is also very convenient. However, when some large files, such as confidential documents, large pictures or videos, need to be transferred at high speed, they will encounter some problems, such as the size limitation of the mailbox, the slow transfer speed of the traditional transfer tools, unstable network connection, and data insecurity, etc., all of these cause the transfer of large files becomes a difficult problem. How to transfer large files quickly and efficiently? Raysync provides you a perfect solution. Based on the high-performance UDP transfer protocol, Raysync makes full use of the network bandwidth, it transfers the large files 100X faster than FTP with minimal packet loss. Multi-dimensional transfer mode meets the various requirements of TB-level large files and massive small files. By adopting the mechanism like breakpoint resume, built-in multiple file verifications, and error retransmission, our solutions enable you to send files of any size or format at full line speed, hundreds of times faster than FTP, while ensuring secure and reliable delivery. With Raysync Large File Transfer, It's never been easier to move data securely inside and outside your organization.
