Maximize Your Bandwidth
Resilio Connect combines several technologies to optimize the data transfer rate:
UDP-based, WAN optimization to overcome latency and packet loss
Peer to peer (P2P) networking moves data in parallel to all locations
Differential sync engine - only moves the data that changed
Data compression - cuts the amount of data that is sent
By overcoming packet loss and latency, moving data in parallel, and reducing the amount of data sent over the wire, Resilio utilizes 100% of the available bandwidth and increases the overall throughput 2-10x compared to other products.
Why P2P Helps?
The P2P architecture greatly improves file transfer times. By better utilizing idle network connections, the effective bit rate is improved. By spreading CPU and disk IO activity over multiple endpoints, we prevent data transfer bottlenecks. In a typical deployment, we increase the overall file transfer speed by a factor of 2-10x.
Impact of Distance and Connection Type
When calculating data transfer rates, it’s important to understand that long-distance connections bring high latency and some loss. Similar behavior happens to network transfer times when connecting over Satellite or 4G/LTE - the round trip time could be as bad as 2,000 msec. Resilio Connect utilizes 100% of the available bandwidth in your network independent of distance, latency, or loss. Legacy transfer protocols degrade by 50-90% over lossy or latent networks.
Why TCP/IP Doesn't Work Well?
When using TCP/IP the sender waits for acknowledgment from the receiver. The time it waits is defined by the TCP Window. In a high-latency network (high rtt), acknowledgments are not received in a timely manner, which in turn makes the sender spend more time idle and not sending any new packets.
For example, a 1 Gbps line with 150 ms delay (latency), will behave like an 80 Mbps line when using TCP/IP. TCP thoughts is 12x lower than the available bandwidth.
Data Size and Data Transfer Time
Your data transfer time depends on many factors: internet speed, latency, loss, network disconnects, and of course file sizes. When sending very large files (many gigabytes or terabytes), it is important to control the size of the file chunks sent over the wire. On a stable connection, sending large chunks is more efficient. On the other hand, if the connection isn't stable, sending small chunks will prevent unnecessary data retransmission and provide an overall higher transfer speed.
“We are a collaborative studio who work extensively with international partners and in particular studios in Mauritius, Singapore and Indonesia. In its effort to exchange large amounts of files between all of these locations, the studio experimented with solutions like Aspera and Media Cloud. Ultimately, it chose Resilio Connect for its speed, flexibility and cost-effectiveness.”

Move Large Files Fast with Resilio
File transfer with Resilio is simple, automatic, and secure. It is the best way to send files to remove employees or collaborate with partners and vendors. In addition, it can handle any file size over any network.
"For us, the main thing was fast transfer of data and obviously maintaining the integrity of all the data that we sync to our offices. And definitely the cost is very important. We were happy to find a solution where we could use our in-place architecture to keep down the cost."

Reduce Sync and Transfer Times
Resilio's proprietary file transfer technology will get the most out of the network bandwidth you have. Give it a try. It is faster than anything you have tried before.
Try Resilio's Universal File Delivery
Resilio unifies file transfer from edge to core to cloud. It works across any device and location. Resilio gives IT teams control over enterprise-wide file transfer by centrally monitoring and visualizing all data transfers across the organization.
“Resilio Connect enables us to reliably distribute our code, specifically new language models in a fraction of time. These copy jobs now take an hour, down from eight. Best of all, once Resilio Connect was installed, it just works: We never need to manually intervene in any way.”
