UDP, or User Datagram Protocol, is used to transfer large files across the internet. While the Transmission Control Protocol (TCP) is the more known and used protocol, it falls short when it comes to transferring large files at fast speeds in comparison to UDP. UDP is commonly used for transferring files for:
Both of these protocols break down large data sets into individual packets that are sent across the internet. They hop from one node to the next until they end up at their destination. Once the packets have arrived, the data set is reconstructed and the file is back to its original state.
Some file transfer protocols like HTTP, HTTPS, and FTP use TCP, which does not perform well in difficult network conditions. Some protocols that use UDP include DNS, VoIP, and DHCP.

While UDP is more lightweight than TCP and requires no dedicated connection, there are still some disadvantages of UDP. Some of these drawbacks include:
IBM Aspera fills the gaps left by TCP and UDP in providing reliable, high-performance file transport. It eliminates the fundamental bottlenecks of TCP- or UDP-based file transfer technologies like FTP and others.
Using standard UDP in the transport layer, it achieves decoupled congestion and reliability control in the application layer. Through that, Aspera retransmits precisely the real packet loss on the channel. Data that is lost in transmission is retransmitted at a rate that matches the available bandwidth inside the end-to-end path with zero duplicate retransmissions.
Using FASP adaptive rate control, Aspera uses measured queuing delay as the primary indication of network congestion with the aim of maintaining a small, stable amount of queuing in the network. This allows FASP to work at high performance while responding to congestion along the transfer path.
