NetEqualizer uses built-in, connection-level equalizing technology to dynamically control traffic based on real-time network usage. This automated approach allows network administrators and operators to maintain high levels of customer satisfaction without purchasing additional bandwidth or becoming quality of service (QoS) experts.

This unique technology is in contrast to the many other static, manually controlled bandwidth-management tools on the market today.

NetEqualizer appliances are flexible, scalable and cost-effective "smart" bandwidth-control products designed for corporate, educational and service-provider networks. They are plug-and- play, allowing network administrators and operators to quickly and easily bring network traffic into balance without having to build and manage extensive policies (rules) and without having to make changes to the existing network infrastructure.

When the network is congested, NetEqualizer’s fairness algorithm acts like a traffic cop and automatically provides priority for latency-sensitive business applications, including voice, web browsing, and email. Low-priority tasks, such as large downloads, are slowed down so the priority tasks receive all the bandwidth they need.

Because NetEqualizer is direction independent, one unit per link will insure a smooth flow in both directions.

How Equalizing Technology Balances Traffic

Each connection on your network constitutes a traffic flow. Flows vary widely from short dynamic bursts, such as when searching a small website, to large persistent flows as when performing peer- to-peer file sharing.
NetEqualizers "equalizing" technology adds latency to low-priority tasks so high-priority tasks receive sufficient bandwidth. By adding latency to the acknowledgment packet, we control the traffic in the inbound and outbound directions. If the flow is still using too much bandwidth, NetEqualizer increases the "penalty" and adds more latency based on the answers to these questions:

• How persistent is the flow?
• How many active flows are there?
• How long has the flow been active?
• How much total congestion is currently on the trunk?
• How much bandwidth is the flow using relative to the link size?

This all is done automatically, requiring no routine maintenance.
