An Alternative Solution to Solve Your Large File Transfer Challenges

Data transfer has played an important role for enterprises to conduct business with its customers, partners and suppliers while acting as its foundation in mining data value. However, the emergence of the Big Data era has spawned a massive amount of data, while various data types and interactive scenarios have become increasingly complex, the efficiency and security of data transfer is also facing its challenges. If enterprises desire to continue extract value and create opportunities, the foremost priority is to tackle data transfer.

Challenges:

● While the amount of data has skyrocketed, the transfer efficiency is still poor;

● Data types are diverse and traditional transferring methods are difficult to guarantee its integrity;

● Network environment is complex while the cases of data loss and leakage are increasing;

● Cross-regional and long-distance teamwork has increased, but high latency and high packet loss rate have also become prominent.

The key to solving the challenges above is to find a first-class data transfer engine. This would eminently support enterprises to build a high-speed, secure, and stable environment for data transfer, which brings an edge to lead in a data-driven development.

The Great TCP Bottleneck

Transfer protocol is the foundation beneath every data transfer, in which TCP is the most commonly used IP transport layer protocol. Compared to other protocols, TCP is able to provide a more reliable service for establishing connections between specific network systems and applications.

Originally developed in the early 1970s when networks were still local and data files were small, TCP served as the basic protocol which enabled data to move efficiently and reliably within the local area network (LAN) with very small bandwidth. To maintain this reliability, TCP ensures that the application data transmitted in a single TCP connection arrives at the receiver’s application in the same sequence as when it was sent. Therefore, TCP uses an algorithm to establish the connection between the sender and receiver, creating transfer requests in turn, and splitting the data into packets, which are then sent separately through the network without the need for acknowledgement until reaching its definition limit. (This operation is known as TCP windowing).

The sliding window protocol is used by TCP to define the data buffer. Figure 1 below is a simplified diagram that demonstrates how TCP sends out small packets over the network and how TCP windowing controls how much data can be transmitted without acknowledgement. As the packets are delayed, TCP will then slow down the transfer rate with a smaller window size, which further limits the number of unacknowledged packets allowed.

TCP algorithm is proved to be effective when data transfer occurs over a short distance while the network is not congested. However, when the round trip time (RTT) of packet transfer is inevitably increased by distance, both the performance and efficiency shall be affected. Especially under the scenarios of long-distance, transnational transfer, the transfer of large files and massive small files will expose the drawbacks of TCP protocol:

● Low transfer efficiency, end-to-end transfer requires sequence acknowledgement, the data processing is slow;

● Increase of data loss rate and latency when large files are transmitted;

● Extreme congestion control throttling which results in unnatural throughput loss;

● TCP cannot guarantee its reliability, its file check mechanism is imperfect.

In essence, TCP cannot be defined as a reliable transfer in the true sense of the word. Especially under the pressure of data volume and distant transfer, TCP is unable to guarantee the efficiency of transfer and yet it may expose enterprises to data security threats.

Raysync – A Brand New Transfer Protocol

Raysync’s high-speed transfer protocol is a core transfer technology developed by Shenzhen Yunyu Technology Co., Ltd. based on the UDP transfer protocol. This breakthrough technology does not simply optimize or accelerate data transfer but it takes a leap forward in the transfer technology to completely eliminate the underlying bottleneck while overcoming the limitations of traditional network and hardware. Raysync is able to fully make use of network bandwidth thus provides an ultra-low latency, high speed and end-to-end output service. The transmission rate can be increased by nearly 100 times, achieving over 96% of bandwidth utilization rate while easily adhering to the security, controllability and stability requirements for TB-level large files and massive small files transfer.

Transport Layer: A Black Tech that Overthrows the TCP Protocol

The TCP transfer protocol does provide a reliable data transfer under ideal conditions, but with its fixed throughput bottleneck, a prominent and serious condition would occur due to high packet loss and latency caused by a long-distance network transfer.

Raysync guarantees reliability in the application layer with an innovative method that eliminates drawbacks such as low efficiency in TCP, packet loss, processing errors and unstable transfer rate. To ensure 100% reliability, Raysync adopts the best mechanism that accurately identifies and passes on the actual packet loss condition on the transfer channel.

Application Layer: Best Alternative to FTP

The FTP transfer protocol has been used for more than 40 years, but it is also a fact that the efficiency of FTP file transfer has been far less than the growth rate of data in the face of today's complex file exchange requirements. FTP is even worse in the file management tasks that enterprises urgently need today.

In order to transfer files while maintaining security through FTP, this requires complex scripts, continuous maintenance, and even other applications to assist. All of which may cause time and money losses to enterprises by varying degrees.

Basing upon UDP’s high-speed transfer protocol, Raysync breaks through the bottleneck of large file transfer which satisfy enterprises’ needs by building an intelligent transfer platform that processes and integrates massive data at an unprecedented speed.

Financial Industry

Challenges:

Most financial institutions expand and develop through their branches, but this often leads to fragmentation of data and application environment. And when "organizational performance" becomes the priority of business development, it is necessary for them to collect a vast number of operation logs and integrate the data to improve the efficiency of business development.

Solutions:

● Raysync’s admin console allows financial enterprises to quickly collect operation logs, monitor transfer logs, manage user groups, configure file permissions, etc. to promote the rapid improvement of its organizational performance.

● In the meantime, the AES-256+TLS encryption algorithm also plays an important role in the whole process, providing top-level security for the financial industry.

Medical & Health Industry

Challenges:

The problem of isolated data islands has long plagued the health industry, potentially hindering the data analysis to improve the overall quality of medical and health services. In the meantime, the issues with transfer and data storage that is directly related to customers’ sensitive data and massive data generated from genetic research have also impeded the development of the medical and health industry.

Solutions:

● Raysync’s large file transfer solution helps to integrate the data across different islands and systems, providing a unified data set for medical and health providers, researchers, and institutions. This is extremely convenient for the stakeholders to collect and analyze data to accelerate the leveraging of Big Data.

● In order to tackle the issues of transferring sensitive data, Raysync adopts standard bank-level encryption and an effective file management system to provide a secure environment for users retrieving the data and the data itself.

With the evolution of information technology continuing at a rapid pace, enterprise data transfer is no longer a simple matter. Especially in such complex market conditions, enterprises should not only consider whether the transfer technology is powerful enough but should also take high-quality service guarantees into consideration when choosing the right solution.
