Traffic Shaping

Continuous Computing has extensive insight into Deep Packet Inspection (DPI) and Packet Processing. We understand the necessity for network equipment providers to incorporate traffic management and traffic shaping into their 3G / HSPA+ and WiMAX / Long Term Evolution (LTE) infrastructure quickly and cost-effectively.

DPI / Packet Processing is strategic for Continuous Computing; we have 13 DPI / packet processing wins and we serve three of the top four traffic management providers.

We invested early (and heavily) in ATCA DPI / packet processing platforms to deliver application-ready FlexTCA platforms that support packet processing-based functions.

Because of this foresight, we are the market leader in ATCA DPI / packet processing.

What’s more, the thought leaders within our engineering and product line management teams have written extensively about the specific requirements of, and opportunities for, traffic management and traffic shaping:

• Lethal Cocktail: Internet Traffic Offloading & Traffic Shaping Do Not Mix Well
• Use DPI to Increase Mobile Subscriber ARPU Despite Flat-Rate Plans
• Why Do 3G and LTE Need DPI?
• Bringing DPI into Wireless Networks
• DPI: Managing Data Traffic in LTE Networks
• Achieving Higher Performance in a Multicore-based Packet Processing Engine Design

To illustrate our system-level approach to addressing Traffic Shaping key requirements, let’s drill down a layer.

Adaptive Traffic Shaping

Unlike wireline networks such as FTTx, DSL or cable, mobile broadband presents new challenges due to the physical limitations of the radio interface.

Wireless networks must operate within defined radio interface and spectral restrictions, so carriers cannot “throw more fiber” at the problem. Managing traffic is thus a critical requirement for network operators.

Continuous Computing’s patent-pending Adaptive Traffic Shaping architecture is designed to deliver DPI / packet processing-based policy and service control for the core network.

The Adaptive Traffic Shaping architecture is capable of analyzing traffic and allocating services, bandwidth and priority based on a number of configurable parameters including user, application type, time of day and service level.

Uniquely, the Adaptive Traffic Shaping architecture leverages user information from the Radio Access Network (RAN) to determine if a specific base station is becoming congested. This added dimension allows for policies that take account of base station traffic, enabling shaping and congestion management based on air interface loading as well as traditional GTP tunnel ID / user-based load balancing.

The incorporation of RAN status information is not a feature typically found in traditional policy enforcement solutions and is therefore a key differentiator of the patent-pending Adaptive Traffic Shaping architecture.
