FTP) is a common protocol in the file transfer process. Many companies build FTP servers to provide file download services.
Here are two transfer modes for FTP. FTP differs from other services in that it uses two ports and one data port. And a command port . Usually, port 21 is the command port and port 20 is the data port. When the concept of active/passive mode is mixed in, the data port may not be 20.
Active Mode
The working principle of the active mode: FTP client uses N port to connect to port 21 of the FTP server, sends a user name and password to log in, and after successful login to list or read data, the client opens the N+1 port. Send the PORT command to the FTP server, tell the server-client to adopt the active mode and open the port; After receiving the PORT active mode command and port number, the FTP server connects through the server's 20 port and the client's open port to send data.
Passive Mode
The working principle of the passive mode: the FTP client uses N to connect to port 21 of the FTP server, and sends a user name and password to log in. After successful login, if you want to list or read data, send a PASV command to the FTP server. Open a port locally , and then tell the client the open port. The client then connects to the open port of the server through the N+1 port for data transmission.
Active Mode VS Passive Mode
The difference between the two is that when establishing a data movement connection, the main mode connection initiator is server-side, and the port 20 connects to the client's N+1 port to establish the data connection; the passive mode connection initiator is the client, and the client uses Port number +1 to connect to a high-order part of the server.
Differences IN Network Settings
Scenario: The FTP client and server are on different networks, and a firewall is required between the two networks. The client's FTP software sets the port segment opened in active mode, and the corresponding port segment can be opened on the client's firewall. There is a common problem: only port 21 is opened on the server-side, and no port is opened on the client machine. The passive mode adopted by the FTP client connection results in that the client can log in successfully, but cannot list and read data. It is because the server does not open the random port in passive mode.
In passive mode, the open ports on the server-side are random, but the firewall must not be fully open. The solution is to open some random high-level ports in the passive mode of the FTP server configuration , and then set the rules in the firewall, open the corresponding port number on the server-side.

![[2022] How to Solve Large File Transfer Problem?](http://images.ctfassets.net/bg6mjhdcqk2h/5Sh4LomwQy3w4kPuwpVsXp/6e39126535a196088ec4d130ef6edaed/large-file-transfer-solutions.png)
Large file transfers are often a huge challenge for organizations, especially when data needs to be transferred across long distances and scattered servers in a short period of time. If you do not have the right toolset to try to transfer large files, it means that the massive file transfer process may face risks of data security, high latency, TCP/IP transmission limitations, data transmission failure, data loss, and inefficient use of bandwidth.
With a fast file transfer solution equipped to handle large files, you will not face the lack of SLA and critical deadlines, and you don't have to spend time worrying about when large files will arrive at their destination, just as you need. You are forced to carry or transport a hard copy of the data.
The problems solved by fast file transfer solutions include low bandwidth utilization, excessively long delays causing file transfer bottlenecks, slow, inaccurate and inefficient file transfer processes, large file transfers, long-distance file transfers, including large data set transfers.
When evaluating vendors and fast file transfer solutions, it is important to understand the common data transfer challenges caused by data transfer delays and the help of fast file transfer solutions.
Bandwidth is the amount of data that can be transmitted in a certain period of time. Bandwidth utilization is the amount of bandwidth used compared to the total bandwidth available. Always use all the bandwidth you pay for. Your company has purchased a certain amount of bandwidth from your service provider. How much bandwidth you pay depends on the maximum bandwidth you expect to use. However, only when there are occasional peaks do you actually use all the bandwidth you paid for.
Latency is the time it takes for the file to be transferred across the network. Delay has negative connotations, such as "the delay of the network is slowing down my transmission speed". Latency + bandwidth defines the speed and capacity of the network.
File transfer Protocol/Internet Protocol, the most commonly used protocol for Internet communication, TCP is optimized for accurate delivery rather than timely delivery. Therefore, TCP sometimes causes long delays when waiting for retransmission of out-of-order messages or lost messages. It is not suitable for real-time applications such as VOIP.
The data is divided into several parts and sent as individual "data packets", and then these data packets are recombined at the receiving end. The extra data is added in the form of a "header" that tells the receiving end how to reassemble the data packet and ensure that everything sent is actually received. This will split the file and reassemble the file, sending confirmations back and forth to ensure that there are no errors that will slow down the transmission .
Raysync is a secure and high-speed file transfer solution. Providing a file transfer alternative to existing FTP servers. Raysync allows you to significantly reduce file transfer times and manage file via an easy to use user interface.

It can exert high efficiency and stable performance without special adjustment.

The value of any organization's technology integration depends to a large extent on the quality of its big data for digital transformation machines. In short: big data can achieve digital transformation, anyway, this is the goal.
So how can big data technology bring success to enterprises in the grand plan of things? It turns out that it is not as good as hope. Optimistic expectations for big data may exceed our ability to actually execute big data.
The latest research on the UK online consulting and consulting platform shows that 70% of big data projects in the UK have failed. The study goes on to say that almost half of all organizations in the UK are trying to carry out some kind of big data project or plan. However, nearly 80% of these companies cannot fully process data.
However, this is not news. About three years ago, Gartner, a leading research and consulting company, reported similar situations on a global scale and predicted that 60% of big data projects in 2017 would fail the early implementation stage. Worse, this forecast is too conservative, because 85% of big data projects that year ended up flat.
So why do so many initiatives fail to meet expectations? When trying to drive value through big data projects, what measures can be taken to increase the likelihood of measurable success?
The promise of big data, despite the fact that so many organizations are still working on big data projects, there are some reasons.
Volume and speed——Data explosion: exponential data from more sources from increasing speed of creation
Diversity——Mobile and IoT terminals, the proliferation of traditional data types and the massive increase in the amount of unstructured data
Accuracy——As the saying goes: "Garbage in, garbage out." Big data projects are only as good as providing data.
Value——The white rabbit of big data. Discovering influential insights or new value streams for the organization is the biggest challenge. It is a symbol of differences in potential income and competition. Value is the reason for entering big data in the first place.
The continued potential of analytics and the prospect of deliverables have turned big data into a multi-billion dollar technology industry in less than a decade.
This has a lot to do with McKinsey Global Institute’s 2011 bold prediction of big data: “Big data will become the key basis for competition, providing support for a new round of productivity growth, innovation, and consumer surplus, as long as there are correct policies. And the driving force is in place."
The idea is that almost every company in every industry is located in the large diverse, scattered, and disorganized enterprise data left in traditional systems and infrastructure. In the gold mine. Generated by a business. In order to obtain this treasure trove of information, each company needs specialized access and analysis tools to properly connect, organize, and ultimately transform it into a digestible and analyzable form.
Assuming success, the big data infrastructure is expected to provide:
Connect and unify all data sources
Generate powerful business insights
Allow predictive decisions
Build a more efficient supply chain
Provide a meaningful return on investment
Comprehensively change every industry
Although the potential of big data has been proven to be successful in many cases , the final state of big data required by most organizations has proven to be a difficult problem.

data transmission

At work, you cannot avoid transferring large files. For example, some times you need to transfer a video file to colleagues who are more than 1,000 kilometers away. Or you need to transfer large files to colleagues in the United States. It is very difficult to send large files without a large file transfer tool or software. The website can be more convenient in transferring large files, saving time and efficiency.
Let me introduce you to the website that high-speed file transfer solutions—Raysync.
At present, when transferring large files of several GB internally, usually by means of network Cloud Disk, FTP, Mailbox, etc., if the file capacity is large, it may be sent directly to the hard disk. The time for express delivery in the same city is relatively short. However, if it is not in the same city, it will basically take 2-3 days, and the latest documents cannot be obtained in time, which seriously affects work efficiency. Therefore, how to securely transfer large files is a difficult problem that we are faced with.
So what are the aspects of the solution for Raysync large file transfer? Raysync provides large file transfer solution that can realize global data interaction, allowing quick distribution of line-of-sight data among internal users, corporate customers and partners, and solving the problems faced by file transfer.

Transferring large files is critical for most businesses, but how do you ensure that the files are suitable for the right person, and not others? When considering factors such as security, bulk transfer and tracking, companies need more than a one-stop solution, but also need to share files and send large files with employees, customers and trading partners.
Why is it So Hard to Send Large Files?
Enterprise send large file transfer status
1. Slow Transmission Speed
a. Large file transmission In the transmission process, there are transmission problems such as low transmission speed and high delay.
b. Low bandwidth utilization, slow upload, and download of large files, which reduces the efficiency of the enterprise.
For example, enterprise cross-region employee file transfer, enterprise, and cross-region customer file transfer, enterprise cross-region IT system file transfer.
2. High Latency and Easy Packet Loss
Cross-region file transfers can easily cause long delays, serious packet loss, and low rates.
3. Security Flaws
a. Using FTP transmission mode, too many open transmission ports, the firewall is subject to attacks such as hackers, virus attacks, resulting in transmission security is not guaranteed.
b. Failure to transmit large amounts of data promptly causes data errors, and manual error checking is too cumbersome.
c. Sending large files in the form of receiving and sending hard disks. Once lost, the consequences are unimaginable.
d. Too frequent FTP transfers cause firewalls to be attacked, resulting in information leakage.
e. A large number of files cannot be transferred in one go, and files are easily lost.
4. Lack of Stability
Large files cannot be transmitted completely, and packet loss is likely to occur during the transmission process, which cannot guarantee data integrity.
How to Send Large Files?
Enterprise teams need to collaborate across the globe for long-distance cooperation to distribute, share, and exchange TB-level data files, which requires high-speed transmission of big data around the world.
Fortunately, whether you send large files to recipients or let users access them in the cloud, there are many options on how to share large files. Depending on your use case, some solutions may be more appropriate than others.
Raysync is not affected by distance, file size, and network conditions. The transmission speed can be 100 times faster than FTP, which solves the problems of security and transmission efficiency.
The deployment is simple, a pure software solution. There are different solutions for different transfer needs and scenarios.
Raysync adopts C/S mode, the server is built on the company's server, and the data is stored on the company's server. In the transfer process, UDP + TCP check and AES-128 data encryption are used to improve the transmission efficiency of the transmission enterprise. In the case of a bad network environment, UDP transferring has higher applicability than TCP transferring.
To fight with this worldwide crisis, Raysync rolled out a free trial to help your business better respond to the challenges.

Enterprises usually meet the needs of file transfer, how to transfer files? The solution can make the four most common file transfer types, each of which has a more efficient and safer method. There are four different scenarios for file transfers in an enterprise. Let us learn more about them and file transfer applications.
Large file transfer
Flowing data, a five-part file transfer series focuses on key issues, such as security and efficiency, and how large file transfer solutions can help companies solve these problems. The following four application scenarios, understanding the large file transfer application is actually a good solution.
Enterprises usually encounter four types of file transfer scenarios. You can see which of the following happens in the enterprise!
1. Temporary file transfer
These are user-initiated file transfers. For example, after discussions with overseas partners, business users may need to send large files to keep the project running. Many companies find that this type of temporary collaboration is increasing, so file transfers are also increasing.
2. Regular file transfer
These file transfers occur repeatedly. For example, you may need to send daily transaction records from a distributed location to the headquarters, or you may need to back up log files once a day.
3. File transfer between people
With this type of file transfer, a single sender transfers the file to a specific individual. View the files in the specified directory by deploying a radium speed server to set up a specified account.
4. Server-to-server file transfer
In this case, the file transmission is initiated by the process and is automatically received by another process to achieve the function of file synchronization.
When exploring large file transfer solutions, how to improve the efficiency of transferring large files is an important consideration. However, this is not all. After all, it is the key to solve the problems encountered by enterprises in different application scenarios for transferring large files.

Secure file transfer is information sharing via a new secure, reliable delivery method. It is employed to safeguard proprietary in addition to personal data inside transit with rest.
Whether through e-mail, file transfer process , or by means of the Web, peer to peer is part of every business. The particular problem is that these methods are not really an easy task to manage. How do you know who sent what and when and who received it? How do you ensure that sensitive documents usually are sent securely and that they can be retrieved after the recipient finishes the sensitive record? Each day, companies in addition to other entities require to share documents within their businesses and between their particular larger external systems. Most dependable file sharing methods use regular protocols, including:
SFTP
SFTP exchanges files with all the Secure Shell connection – SFTP is usually an encrypted community protocol that could enable remote login to operate over a new network that is lacking in security. SFTP ) is a secure file transfer protocol. It runs within the SSH protocol. This supports the total security and authentication functionality of SSH.
SFTP offers the security of commands in addition to data. It likewise prevents passwords and sensitive information coming from open transmission above the network. SFTP also protects towards password sniffing and man-in-the-middle attacks. That protects the integrity of the info using encryption in addition to cryptographic hash capabilities and authenticates the two the server and the user.
SFTP has pretty much-replaced legacy FTP being a file transfer process and is quickly replacing FTP/S. This provides each of the functionality proposed by these methods, but more securely and more reliably, with easier settings. There is not any reason in order to use legacy protocols anymore.
FTPS(File Transfer Protocol)
FTPS gives encryption and makes use of an application coating wrapper, known since Secure Sockets Layer to enable secure and exclusive communications across a new network.
FTPS is an extension towards the commonly utilized File Transfer Protocol that gives support for your Transport Layer Security and, formerly, the particular Secure Sockets Level cryptographic protocols.
FTPS uses a consumer ID and password, certificate, or the two to verify your connection. When hooking up to a buying and selling partner's FTPS server, your FTPS client will first verify whether or not the server's certification is trusted. A new certificate is signed if it is signed by simply a known document authority or if it is signed by your current partner in addition to a new copy of their public certificate inside the trusted crucial store is considered a new trusted certificate. If your certificate is not signed with a third-party CA, your spouse may permit you to self-sign the certificate plus send their open public parts to all of them ahead of time to weight into their trustworthy key store.
HTTPS
Hypertext Transfer Process Secure is surely an extension of typically the Hypertext Transfer Process . It is employed for secure conversation more than a computer community and it is widely utilized on the Internet. In HTTPS, typically the communication protocol is usually encrypted using Transport Layer Security or, formerly, Protected Sockets Layer . The protocol will be therefore also referenced to as HTTP over TLS, or HTTP over SSL.
The main motivations with regard to HTTPS are authentication in the accessed site, and protection regarding the privacy in addition to integrity in the changed data whilst in transit. HTTPS secures web sites when users are providing sensitive details like credit card amounts or other individual information. The process offers multiple layers of data protection including data honesty, encryption, and authentication. It protects against man-in-the-middle attacks, and the bidirectional encryption of communications between a client and server protects typically the communications against eavesdropping and tampering. Used, this provides the reasonable assurance that one is contacting the intended site without interference coming from attackers.
AS2
AS2 is a specs about how to transportation structured business-to-business information securely and dependably over the Web. Security is attained by using electronic certificates and security. AS2 is actually a regular used to transfer Electronic Data Interchange messages along with other data in the current. The AS2 process facilitates the capacity to exchange AS2 EDI messages in addition to other types regarding data over the particular HTTP or HTTPS protocol.
MTF
Managed file transfer refers to an application or a service that manages typically the secure transfer regarding data from one personal computer to another via a network . MFT software is marketed to corporate corporations as an option to using ad-hoc file transfer remedies, such as FTP, HTTP, and other people.
Protect Your Files with Industry-Leading MFT Software
