Wireless ISPs

Before Bequant we were constantly getting complaints like “my Netflix is buffering” or “I am running slow” even though the customers were receiving their full allotted bandwidth. In the last two weeks since implementing the Bequant solution we have not received a single complaint! What a relief. It has been worth every penny. It is a great solution for the shortcomings inherent in the WISP industry.

The testing of this TCP optimization technology has been satisfactory, obtaining very good results in several scenarios of packet loss, such as with interference or low SNR, and also without interference and high subscriber density that place the network close to full capacity. All this translates to a substantial improvement in customer experience in video and online TV, achieving perfect visualization in adverse scenarios and a remarkable quality improvement in adaptive scenarios. Browsing is also a strong point, with an acceleration over 50% in loading times of big pages

Overview

The Bequant TCP Acceleration (BTA) overcomes TCP performance issues in wireless networks to significantly increase the network speed experienced by users. This improves the quality of experience (QoE), the customer satisfaction and loyalty and the operator reputation, yielding higher revenues.

A WISP network topology sometimes requires more than one wireless link, and a home WiFi very often is added as well. This path with multiple wireless hops is more complex and difficult for TCP traffic to adapt to. The BTA has a highly optimized TCP stack that excels in such difficult scenarios.

The BTA improves the fairness between traffic flows during network congestion (the equitable distribution of the total network capacity among all the competing traffic flows) improving the overall network behavior at full capacity. The BTA also resolves retransmitted traffic locally to the WISP network, which reduces interconnection traffic.

Acceleration Results

This section shows the acceleration obtained with all the live traffic of a WISP network with licensed-band wireless links. 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 average speeds over a week, with consistent acceleration effect in all network conditions. The image was generated in real time by the BQN online WEB interface, and provides 9 graphs for different categories depending on the download size and internet RTT.

Deployment

Bequant software runs on Bequant Nodes (BQN), which are transparently deployed as a bump-in-the-wire between the access gateway router and the Internet gateway router.

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/QoS policers or shapers. The BQN supports PPPoE and VLAN traffic seamlessly.
