Optimization

Accelerate your network

Speedometer icon

TCP is the most widely used protocol in the Internet, but, like other transport protocols, when networks are not perfect, it tends to transmit at a lower speed than what the network allows. The Bequant TCP Optimization functionality, makes sure that TCP traffic flowing through it reaches optimal speeds, resulting in faster downloads and uploads.

1.1

The challenge

Transport protocols are often the bottlenecks.

Transport protocols (like TCP, the most common, or QUIC) use algorithms to find the optimal  speed at which data is sent on each connection. To avoid collapsing the Internet, they are designed to send at a lower speed when they detect congestion. However, they often detect congestion incorrectly  in non-congested connections going over wireless links, lossy networks, or when latency is high. As a result, in those non-perfect (but very common) networks, they end up transmitting at a significantly lower pace than what the network would allow.

TRANSPARENT TCP PROXY

Bequant increases the speed experienced by network users.

The Bequant BQN platform will act as a transparent proxy for every TCP connection in the network, which will increase their speed in two ways. First, because as a proxy, contents will effectively appear closer to clients, and closer always means faster in Internet. Second, because our enhanced TCP will still send at the optimal speed in non-perfect networks, thanks to its automated learning algorithms.

The solution

The BQN Platform uses a transparent TCP Proxy to improve performance.

Visualization of a transparent TCP Proxy

The Bequant BQN works as an in-line transparent TCP proxy (as defined in RFC 3135), to perform TCP Optimization, making data appear closer to TCP clients, which results in a faster delivery. While this kind of proxy has been used in many years in satelite and cellular networks - Bequant has made this advanced technology available for all networks, and improved it using the most advanced automated learning algorithms.

Improve your performance.

Faster TCP Stack

Detect congestion with a faster TCP Stack.

The Bequant TCP stack detects congestion based on the measured delivery rate, as described in our patent portfolio. Our improved congestion detection algorithm allows our TCP to be more aggressive when there is no congestion and to back off in real congestion, being able to carry out this discrimination in challenging environments: with shallow buffers, wireless links, packet losses or large network delays.

Different Environments

Results in Different Environments.

Our TCP Optimization has been in operation for years in over 250 ISP and enterprise networks around the world. The following graph shows the average speed of all Netflix downloads in very different networks, from Wireless ISPs to fibre and cable networks. In each case, over a one-week period, we measured the speed of Netflix downloads accelerated by our application and Netflix downloads that were not being accelerated, and compared the results.

Since deploying BQN, the amount of support calls complaining about low speedtest.net results and buffering when streaming via internal wifi dropped tremendously.

Overall, we have a much happier customer base.
