The client app doesn’t need to be installed, but simply run. ExpeDat setupĮxpeDat is a server component that works together with a client app (available for macOS, Windows, Linux) and allows end users to connect. The transfer is fully encrypted and integrates very well into the ELEMENTS platform. Their MTP protocol that powers this solution is based on UDP and is able to adjust flow and correct transmission losses in real-time. However, one simpler and considerably less expensive solution is ExpeDat from Data Expedition, Inc. Some of the best-known players in this market are IBM Aspera and Signiant. UDP (User Datagram Protocol) is a communications protocol primarily used to establish low-latency connections between applications over the internet.Īlthough UDP is often associated with connectionless services like DNS or video streaming protocols like RTP, a number of companies have used it as the basis for implementing modern algorithms that can fill up even the fastest internet paths.
The best way to achieve high-performance transfer speeds is to leave TCP behind and use a more modern protocol build. But unless you are network engineer, and willing to constantly retune your network stack, you’re probably stuck with whatever defaults are in your operating system. There are many ways to tune TCP for better performance on a particular path, including more than a dozen algorithm variants in common use.
This feast-or-famine behaviour makes it hard for TCP to scale and can leave a lot of bandwidth unused. During the data recovery, TCP slows down considerably only to quickly flood the network again. When a packet doesn’t reach the receiver, TCP only has limited time to recover the data or else it is forced to stop the transmission entirely. Network congestion may occur when a sender overflows the network with a large number of packets which leads to a degraded quality of service through packet delay and packet loss. This is when TCP can start to break down. Today, modern technologies can provide far higher amounts of data and put more pressure on the network. But fifty years ago, CPUs and storage weren’t nearly as fast as they are now, and network congestion was mostly a theoretical problem. TCP (Transmission Control Protocol), the internet’s main transmission protocol has been around since 1974. Just like raising the ceiling doesn’t make you taller, simply having a faster internet connection doesn’t guarantee faster transfer speeds. However, they do require more than just a faster internet connection. Believe it or not, these kinds of workflows are possible even today. Just imagine a world in which all content is quickly delivered to the office over the internet – straight from the set, without the need to juggle SSDs and memory cards. With blisteringly-fast internet speeds becoming the norm, internet transfers are playing an increasingly important role in post-production workflows.
