Fiber/Cable/ADSL ISPs

Bequant is a traffic acceleration system that has greatly improved the experience of our customers. In the WiFi network it optimizes images and video (YouTube, Instagram, Facebook, Netflix, ...) maximizing the quality and the speed. It is also highly recommended in fiber links. Very easy to deploy: zero problems, zero maintenance, just connect it and you see the difference from day one

Overview

The Bequant TCP Acceleration (BTA) in the Bequant BQN product overcomes TCP performance issues in fiber networks and domestic WiFi access, to provide tangible improvements in the quality of experience (QoE). Better QoE increases customer satisfaction and loyalty and raises the operator reputation, leading overall to higher revenues.

TCP has difficulties to reach fiber high speeds, specially when combined with a WiFi wireless access at customer premises. The BTA tackles these performance issues and raises the effective speed with real applications closer to the high nominal speed of fiber access.

The Bequant DPI functionality provides information about what services are being used by subscribers. That information can also be used to identify specific services and to control their speed when there is congestion, using the Bequant Bandwidth Managment (BBM) functionality.

Acceleration Results

This section describes the acceleration obtained with all the live traffic in a fiber ISP network. The performance of each individual TCP transfer (downlink and uplink) is registered and the accelerated results are compared with the non-accelerated ones to obtain the acceleration percentage (the increase in average speed). Additionaly, you can also look at our Netflix results in different kinds of ISPs.

This chart shows a comparison of the downlink mean speeds for different services.

This chart shows a comparison of the uplink mean speeds for different services.

Bandwidth Savings Results

The following graph shows the results of limiting the speed of streaming video, identified by the Bequant DPI functionality, to 2 Mbps per user in a cellular mobile network. The 2 Mbps limitation was enforced during even hours of the day, while no limitation was set on odd hours of the day, and the total volume of traffic sent every hour, for the whole network, was measured for four days. It can be seen that the overall volume of traffic was significantly lower (around 15% lower), and that the peaks in traffic were also lower when limiting to 2 Mbps. All these results were obtained with no customer complaints due to quality.

In an ISP, a higher speed limitations is required, from 3 to 6 Mbps, since subscribers can use high definition TV sets where lower resolutions are more noticeable. It may also make more sense to enforce this speed limitation only during peak hours, and to include software update services to the controlled applications during those times.

Deployment

The Bequant software runs on Bequant Nodes (BQN), which are transparently deployed as a bump-in-the-wire between the edge router/switch and the next router/switch towards the Internet. The BQN supports PPPoE and it can also be deployed between the Edge router/switch and the users.

The BQN only needs to be on the path of the traffic to optimize and it is compatible with other network elements such as traffic policers or shapers. It can also be deployed between clients and the edge router/switch, for example. The BQN supports PPPoE and VLAN traffic seamlessly.
