Bandwidth
Management

Manage your network

The BQN platform allows you to enforce bandwidth limitations in a flexible and economical way, with the most advanced queueing technology in the market, which will deliver the best possible Quality of Service (QoS) and Quality of Experience (QoE).

2.1

The challenge

Interactive flows suffer from congestion and speed limitations.

When speed is limited, network packets have to wait in queues to be delivered, which increases network latency and can create packet losses. As a result, the network Quality of Experience may be severely degraded, especially for interactive applications, like on-line games and teleconferences, which are very sensitive to latency and losses.

The solution

Minimizing latency by providing independent queues and prioritizing interactive flows.

Limit rates without impacting online gaming and teleconferences

Our unique multi-queue technology guarantees an independent queue for each connection, without any sharing (unlike competing solutions). Multiple independent queues ensure that interactive data do not have to wait in queues with heavy traffic, like video streaming. Moreover, interactive queues are prioritized. In this way, interactive applications will not notice the rate limitation, even in congestion situations.

Subscriber flows

Flexible and economical bandwidth management.

The BQN platform allows you to implement sophisticated  subscriber speed plans, with additional rate limitations for specific applications (identified via DPI), as a function of the traffic congestion situation, and taking into account different access network parameters. All this in an efficient software implementation, delivering up to 150 Gbps in a 1U off-the-shelf server, and easily integrated with billing and subscriber management systems via RADIUS or REST API. We can thus enforce subscriber rate plans at a lower cost than alternative solutions.

1.4

Latency measurements

Reduces latency
and packet losses.

The technology actively reduces the size of queues, including non-interactive ones, enforcing CoDel for UDP queues, or, even better, acting as a transparent proxy for TCP (which can directly control the sending speed at the source server). This results in a significant reduction in latency and packet losses.

GRAPH EXPLAINED
The graph shows latency measurements, and how they went down by 20% when our Bandwidth Management started to enforce the subscriber rate plans.

We have used Bequant to implement the speed limitation of our subscribers, and we have obtained a significant reduction of latency and greatly reduced costs, as we need fewer PPPoE servers in our network. In summary, better quality at a lower cost.
