Channel Bonding

Multiple connections, maximum speed

Channel bonding is a method for utilizing multiple Internet connections for increased throughput and redundancy. Our implementation uses a cloud server component to seamlessly combine all the data transferred across your various Internet connections.

First off, lets touch on the basics

Get ready to learn the differences between packets and sockets as well as why the Internet is just a “series of tubes.”


A networked computer system that handles requests for data
Servers index, send and receive data across the Internet.

When you request a webpage (such as this one) your browser connects to the appropriate server which finds and delivers the necessary files.


A single end-to-end connection to a file on the Internet
A socket is like a tube for information from a server to you.

Each of the various components of this webpage such as the text, images, videos, etc were delivered by a server to your computer over individual sockets.

If a socket is a tube, packets are the liquid flowing through it.

The image to the right was first broken up into thousands of individual packets then delivered through a single socket to your computer and reassembled by your web browser.

Your computer and the Speedify application collectively act as the “Client” and work together to route all your Internet traffic to the correct destinations.

Now lets put the pieces together

Channel bonding makes it possible to spread individual packets amongst multiple Internet connections. By splitting all your web traffic at the packet-level even large single socket transfers such as VPNs, streaming movies, and uploading and downloading files can be given a major speed boost!

This is accomplished by first using the Speedify client software to establish a connection to a Speed Server in the cloud which acts as a middleman between you and the rest of the Internet. The Speedify client software then works in tandem with the Speed Server to intelligently divide your Internet traffic and deliver the combined speed of all available Internet connections.

Channel bonding also offers robust failover capabilities, so even if you unplug one of your Internet connections during an important upload or download your transfer will keep on transferring!

Let’s compare other aggregation methods

Load Balancing

A load balancer runs locally on your PC and spreads sockets amongst multiple Internet connections to increase overall performance. The big caveat here though is that applications need multiple sockets to see big improvements, as no individual socket can be sped up beyond your fastest available Internet connection.

Web browsing and BitTorrent transfers generally utilize lots of sockets, so load balancers work well with them. But, they can’t speed up streaming content, VPNs, or large uploads/downloads as each of these activities happen over a single socket.

Here is a handy table to highlight which activities work well with each service
